As a bonus, the well-produced DAC 2009 video features company executives in a music video with cheesy parodies of some classic rock songs. I'm amused, but Al Yankovic need not worry.

I got to wondering -- which tool has the biggest lock on a major piece of the EDA tool constellation? (I originally wrote "monopoly" instead of "franchise", but don't want to connote market manipulation.) From my perspective, three come quickly to mind
You may have other ideas, and I'd love to hear other nominations. Of these three, I think a good case can be made for Design Compiler having the strongest position. The other tools have large market shares, but also competition determined to make inroads.
Who might chip away at the synthesis gorilla? The old and new rivals are Cadence RTL Compiler and Oasys Real Time Designer. Just published on ESNUG is this "marketmonial" (I need a word for a marketing-inspired testimonial): DeepChip.com: "An Oasys RealTime Designer vs. SNPS DC-Topo/DC-Graphical benchmark . A couple of things that I especially like about Oasys' approach:
Time will render the verdict, and the EDA battlefield is littered with past attacks on DC's franchise, but we need competition in all tool areas to continue advancing the state of the art.
Intel, if you need reliable designs to support your latest CPUs, there used to be a variety of companies in the chipset business.
January 2011 had more than its fair share of bad news for Intel, culminating in a very expensive recall of their newest chipsets because of a design defect. Most of the press coverage focused on the financial hit, but us design engineers are dying to know "what happened?". What's most interesting is that the problem isn't a defect that manifests itself right away, but one the causes the component to deteriorate over time. At first, I thought "electromigration". But the best speculation/analysis I've seen this early has been from Mike Demler, who shares his theories in Price for a new SATA I/O $700M. A complete AMS verification? Priceless! and If ever EDA needed a ($700M) proof point on their value....
If that's the root cause of this problem, it's another data point showing fraying at the edges of our tried and true EDA suites: tools are not available or mature to help with analyzing reliability, materials, packaging, etc.
Update: Thanks to a link from Steve Leibson, I came across this very specific description and analysis of the problem.
If you followed the Consumer Electronics Show news at all last week,
you heard a lot about ARM, ARM, ARM.
Mindshare-wise, it would appear to have Intel on the defensive.
(I wonder how Intel feels about selling off their StrongARM now?)
I plan to learn more about ARM's architecture and products. For today's history lesson, Birth of a world beater features one of the original ARM designers.
I'm curious to learn the technical merits of the ARM architecture. Is it inherently superior? Or is the main advantage the scads of software eco-system available, with low-power coming from standard implementation and process tricks?
Technical superiority and business success don't always go hand-in-hand, anyway.
I've attend HOTChips before, and I was amused how all the microprocessor experts
there bemoaned x86's incredible success, even though they knew it was inferior to
[insert your favorite CPU here];.
x86 was just good enough to survive, and had been in the right place at the right time.
Is now the time for ARM?
Early in my career, I got to visit the IBM Burlington fab when they were introducing a brand-spanking-new technology called "CMOS". Little did I know that would be my last chance to set foot in a semiconductor fab. So, I'm always fascinated to see how things look today. Some things I learned:
Created by several fellow EDA bloggers,
this is an intriguing new EDA/Chip Design site
worth visiting and contributing to.
I know that several bloggers and old ASIC hands wanted to put together an open community for sharing opinions and experiences, and this is the most substantive effort to date. (I tip my hat to John Ford's now-defunct "DFT Digest" site, which was a pioneer in this area.)
Could you figure out the answer? To my frustration, I couldn't, without peeking at a few of the comments. It makes perfect sense now. Not a bad puzzle!
I've read Nick's newsletter for a long time and recommended it, his web site, and his book to many people. What I like is that much of it is more sensible and less trite than so many of the job-seeking rules of thumb that you read. I don't agree with him 100%, and some of his advice seems hard to implement, such as refusing to disclose your current salary. But, he has good reasons and it's all worthy of your consideration.
I hope you are enjoying the holiday season and wish you interesting projects and prosperity in 2011!
Past history is crystal clear and his description spot on. His assessment of current and future value-add is plausible and thought provoking. Sounds dire for many silicon-centric companies, though. Will you be a survivor? What does it say for the fortunes of the EDA industry? His answer seems to be focus on system/software, complemented by C-based hardware design.
Beyond 22nm, many things get exotic. Extreme UV (EUV) has been the next big lithography change for ages -- is it finally required for 15nm? FINFETS, Carbon Nanotubes, and Stacked Die, Oh My! We're not in Kansas any more.
But this is much more focused than a merchant ASIC business. FPGA itself is more like a Standard Product, with high volumes and lots of benefit from using advanced processes. Altera and Xilinx are the most leading-edge customers for the established foundries. It'll be interesting to see Intel's motives beyond just "further monetizing the fab".
It's exciting to see GPU Computing gaining traction and accolades for certain highly parallel applications. I'm anxiously looking forward to GPU Computing helping to solve EDA problems. So far, there's been some nibbling around the edges and algorithms experimented with, but I'm not aware of production EDA products based on GPU. Yet. What EDA applications would most benefit from massively parallel processing, such as is offered by a GPU?
Does the same thing happen with EDA software? The state of the EDA business in Asia is something I only know from the occasional rumor. How widespread is EDA piracy? How common is it to "crack" FlexLM? And, is EDA software already heavily discounted in Asian markets?
The last point most concerns American workers. Not only are American competing from a higher wage/cost-of-living, but what if the essential tools of our trade are cheaper overseas, as well? Strike two!
Though I'm not sure I'd always like to be his employee, it is pleasing to be his customer. Customers willing to pay a stiff premium are the sincerest form of flattery.
As my readers know, I find SNUG to be the most valuable conference for hands-on IC design engineers. I always leave with a list of new ideas to try back at work.
Why not launch your publishing career and boost your reputation by showing the cool stuff you've worked on?
Top themes:
Product-wise, Aart emphasized their custom design competitor to Virtuoso, which I don't find super exciting. It's always nice to have a more modern implementation of a workhorse tool, but not earth shattering. Synopsys bread and butter tools, which pay the paychecks, didn't get much air time.
I think some of the market share claims could be misinterpreted (90% of 32 nanometer chips), but that's standard fare for the ways vendors advertise this.
Prof. Horowitz's solution is provocative and plausible, though not a "slam dunk". I'd like him to quantify how much his approach would reduce the total cost of nanometer semiconductor design. Also, how applicable is it to domains beyond processors? Isn't it very difficult to create an "architecture generator" for each domain? For another perspective, here's a blog post reviewing the talk.
Companies on the list relevant to EDA/ASIC engineers:
SURPRISE: EDA cost per transistor is coming down the same learning curve as all the other input costs like materials, chemicals, labor, etc. (above) and it has been doing so throughout semiconductor history.
What is Wally Rhines' prescription for increased EDA value-add (and profits)? EDA vendors
... must incorporate the embedded software development and system analysis costs into their design tools and flows. To the extent this is accomplished, there isn’t a cost problem and the 30%+ per year per transistor cost reduction can be achieved. That’s why EDA companies first became involved in embedded software in the mid 1990’s. That involvement will grow as EDA companies take on more responsibility for the total design challenge and its costs. It’s just part of the evolution of roles in the semiconductor industry. (Walden C. Rhines is chairman & CEO, Mentor Graphics Corporation.)
Although in the short term there are still plenty of us fighting it out for nanometer-scale timing (and now power) closure, the focus on software and systems is plausible for the long term. We must find quantum leaps in productivity to take advantage of Moore's law in semiconductors.
You can see other trip reports and interesting links in the delicious.com sidebar of my blog, where I post EDA and Semiconductor links.
With one notable exception. Did you notice that his list doesn't feature a certain EDA company that's hard to overlook? That's right, Synopsys. He doesn't feature one Synopsys product in his list! That's a curious oversight to me. While I do think that much of EDA innovation comes from smaller companies, Synopsys does hold its own in innovation compared to Cadence or Mentor, but those companies did have featured products in John's list. Are John and Synopsys having a spat, or is he getting ready to roll out his exclusive must-see Synopsys list?
John Cooley is the original user's voice in EDA, and his DeepChip web site and mailing list continue to have the biggest following. I used to think of John as "the Michael Moore of EDA" -- a rabble-rouser, confronting the dominant companies and their executives, and sticking up for the little guy.
He still has that image, but I've come to realize that the in-depth tool evaluations that he posts aren't always the innocent sharings of chip engineers that they appear to be. There's definitely an element of the EDA vendors' PR machines in some write-ups. That's OK, as long as you take them as such. If these articles are really EDA vendor white papers or press releases, at least they're written in a language that speaks directly to the challenges we face in chip design. With that caveat, here's a list of his latest nuggets:
The blogosphere is afire with commentary on Cadence's acquisition of Denali, including
Though I'm not a financial analyst, I do have reasonable familiarity with the stock market. And, being the thrifty guy that I am, I'm having trouble to justify Cadence's valuation of Denali. Pulling a quote from Gabe's analysis post, Denali had trailing twelve-month revenues of $43 million, implying a 6.3x EV/sales. Priced at over 6X Sales! For a company that's been around a number of years, and while it has a healthy business, is not forecast for hyper-growth? How do companies justify such valuations? (I'm asking sincerely--perhaps there's an analysis angle that makes this look like a good bet.)
The more I read, the more I scratch my head about whether this is a good venture for Cadence. Gotta give them credit for trying something outside the EDA product box, though. It seems they are gunning for Synopsys DesignWare IP business, and using Denali to give themselves a jump start.
Caveat: I haven't read Cadence's "EDA360 Manifesto", so I may not fully appreciate the cleverness of their overall strategy.
Though as an implementation guy, I don't use Denali products, the first things that sprang to mind are:
Off the top of my head guess list of bigger deals: CCT (Cadence), Ambit (Cadence), Avant! (Synopsys). Maybe ViewLogic (Synopsys), Verisity (Cadence).
On a more somber note, let's hope that Cadence is able to preserve the technology and brain trust that was able to make Denali a well-established mid-level EDA vendor. Cadence has had mixed success in managing acquisitions, with some apparently not paying off (Ambit) and others holding up well (Verplex).
In the interest of preserving history, I'll list their picks here.
I always thought it curious that Apple supposedly pulled off such an ambitious chip with their first major in-house development. Pundits assumed that it was done with the help of Apple's P.A. Semi acquisition, but P.A. Semi had been focusing on the "Power" architecture, not ARM.
I love technology history more than the average person, but I am dumb-founded that with all the software engineering development, object-oriented design, and graphical user interface work that's happened over the decades, we are relying on a language designed before many practicing engineers were born! (People may complain about Verilog HDL's crustiness, but it's "only" 25 years old.)
Though software engineering is not my principal occupation, I do enjoy programming and languages. I know "C" well enough to quickly shoot myself in the foot, but think Java is a far more elegant language. It's sort of like I've heard that Python is a better scripting language, but everyone still uses Perl.
Anyone have explanations for why "C" remains so popular? Isn't this a significant reason why computers have so many security holes? When you hear about "buffer overrun" and "malicious code execution", think "C" pointers! I can see using "C" for embedded systems if resources are very limited, but otherwise, I'm truly surprised by this survey.
The conference featured record attendance (over 2,100) and a good balance of user papers on verification, implementation, signoff, and low-power design.
Some additional details, not quite as juicy, follow in How Apple’s A4 chip lets iPad run cooler, save battery life. I was most surprised at the claim from "a very trusted source" that PA Semi didn’t do the A4. It was the existing VLSI team. Could it be true? All other speculation I read was that this was the fruit of Apple's investment in PA Semi. (Although PA Semi was working on PowerPC designs, and the iPad's A4 is almost surely ARM-based.)
Update: Business Week's A4 story. I was never expecting Intel to be a contender for the iPad design win. And how does an analyst already estimate the cost of the A4 chip and the iPad's bill of materials? Has anyone got their hands on one outside of Apple?
As good tech consumers, we all have our opinions about the features, price point, and odds of it changing the world. Steve Jobs called it "magical". (Fake Steve says he uses neuro-linguistic programming.)
But I digress. What's the significance for chip-design engineers? Though we won't have the details from a full teardown for another couple of months, Apple did announce that they've designed the central chip in the iPad, dubbing it the "A4". Early coverage of A4 includes
It's intriguing that Apple has consciously decided to build an advanced chip design organization, since they are a consumer electronics company. There are comparable alternatives for single-chip mobile device computers, including the Qualcomm Snapdragon and NVIDIA Tegra. What's Apple's angle in doing it themselves? Is it just their obsessive need for secrecy? Or will they somehow integrate differentiating functions that justify the large investment and risk of running a chip design operation? It flies against the industry trend (which PC manufacturer designs its own chips?), but let's see how this plays out. I'm not foolish enough to dismiss Steve Jobs' ability to Think Different.

A short but encouraging news article at X-bit labs, TSMC’s Problems with 40nm Process Technology Largely Over, reports that TSMC has solved its widely-rumored yield problems with its leading-edge 40nm process. Hallelujah! This would be great news for TSMC, their customers, their customers' customers, ...
An interesting side note is the claim that at present only ATI, graphics business unit of Advanced Micro Devices, Altera and NVIDIA Corp. use TSMC 40nm process technology. Really, only three production users of 40nm? Apparently the design pipeline is getting stretched out over many generations, including 65nm on up to 130nm. Ah, I miss the good old days of 130nm design.
(Tip o' the hat to Daniel Nenni for the "tweet" tip.)

The other is ominous for the long-term: Is Moore's Law near its end? - Now Hear This! - Blog on EDN. But really, running out of steam in less than five years? Be sure to read the comment stream, as there are some good additions there.
My perspective is that a near-term uptick is certainly overdue. By all indications, the US economy is starting to recover, and with it, consumer spending on electronics will get a nice boost. There's certainly a lot of innovation being shown at the Consumer Electronics Show this week.
As for Moore's Law, I think it keeps working as long as we're using planar CMOS. If we have to transition to fundamentally different materials, or 3D structures, all bets are off.
Can you tell I had to reset my SolvNet password today? Does Synopsys really hate customers this much? My feelings haven't changed since I last changed my password.
I'd like to to wish you all very happy holidays, however and wherever you celebrate them. With the recovering economy, may we all have a happy and prosperous 2010.
It's hard to imagine greater evidence of a tremendous impact on computer science than authoring the most cited paper in all of computer science as well as in EDA. Remarkable! Before you follow the links, can you guess the subject of the paper?

Now I read Tech layoffs continue, despite signs of economic improvement and it makes me feel my prior observations are the exceptions to the rule. What's your sense of the current job market?

When I'm out and about doing chores or exercising, chances are I'll be listening to my iPod. But more often than not, I'm listening to podcasts rather than music. Listening to podcasts is an efficient way of "reading on the go". You can catch up on the latest news stories, political opinions, or investment ideas.
Those are my interests; you can find a podcast on practically any topic.
Have you listened to podcasts? Which are your favorites? In our field of semiconductor engineering, there's not a wealth of content. But here are some of my favorite engineering/technology podcasts to get you started.
It's easiest to subscribe through iTunes, but there are other ways using the RSS feed and a "podcast catcher" program. Happy listening!

What's your perception of the ASIC/EDA jobs market? My take is that it's pretty weak, but a number of companies are "selectively hiring". I had a couple of friends leave their struggling design services firm, and they were able to land jobs at established growing companies within a couple of months. On the other hand, there are plenty of engineers who have been looking for many months.
One differentiator is that hiring favors leading-edge experience (e.g., expert P&R and design closure of 65 or 45nm chips), or knowledge (e.g., advanced degree with an emphasis on an emerging hot area).
With the depressed job market, this isn't the best time to wonder about this, but I'm perplexed at the lack of US-born chip design engineers. Of course, it stems from the lack of US-born engineering graduates. This leaves me scratching my head--engineering jobs are not THAT bad. As a matter of fact, they're one of the fastest ways to earn a very good paycheck out of college, with intellectual challenge to boot.
A downside is that engineering isn't the most secure career around. There are regular risks of downsizing or technological obsolescence. It's not a cushy career, but how many are in this age of globalization?
If you want a secure career, at least medicine and law are "less outsourcable". However, if you really want societal respect, security, and a guaranteed comfortable retirement, I recommend becoming a fireman.
In the US, we are so fortunate to attract many of the best and brightest scientists and engineers from the rest of the world. There can be complaints about "H-1B abuse", but there needs to be a system that allows the country to benefit from the great contributions possible from immigrants with advanced degrees.
While I'm not there yet, friends and I do wonder where all the full-career engineers are. Look around you -- do you see many 50-something engineers? I don't, and I wonder. Do they all transform into real estate agents? Or should I worry about a future as a Walmart greeter?

Back before "nanometer design", there was "deep submicron design", and ASIC synthesis users became very concerned about interconnect effects on timing. The first attempt to deal with this was through "Links to Layout", and especially a whole slew of custom wireload model (CWLM) strategies. If you look at SNUG programs a number of years ago, there were more CWLM papers than you could shake a stick at.
A major advance in accounting for interconnect effects was when synthesis tools started to perform "virtual layout" as part of the optimization-estimation-timing analysis loop. The most notable tool to do this was Synopsys Design Compiler Topographical. My colleagues and I did evaluations of DCT starting with 90nm designs, and data indicated better correlation and generally a better netlist for Place & Route.
As we progress from 90nm to 45nm and below, physical considerations are becoming ever more sophisticated. The latest examples are
While "getting physical" has the feeling of more accuracy and general goodness, TNSTAAFL. Though I hope for better quality of results and predictability, I see the following drawbacks
Over the coming months, advanced synthesis users will be putting these latest tools through their paces with real designs. And we'll start to learn whether the added complexity and cost leads to better implemented designs. If not, we can always go back to our old friend the wireload model, trying to get to P&R quickly, where the rubber really (not virtually) meets the road.
Update: I stumbled upon a detailed reply/rebuttal over on the Cadence Logic Design blog! Jeffrey Flieder, thanks for writing this. I very nearly overlooked it.
My pre-DAC post
Looking Forward to DAC
laid out what I hoped to investigate by visiting exhibitors, namely
Well, despite my best-laid plans, I wasn't able to check all these items on my list in two days of roaming the exhibits floor. In some cases (i.e., Asynchronous Design), I didn't find an appropriate vendor. In other cases, my schedule or the vendor's appointment constraints didn't allow me to gather the information. But DAC was a great opportunity to see many vendors, and by careful plan or happy accident, I was able to visit many interesting companies. I'll group my vendor impressions into these categories:
And to top it all off, I just about ran into Joe Costello on the DAC floor. (He was suspiciously near the Synopsys booth at the time.) It should be great to have Joe back in the EDA industry. I like and respect Aart de Geus a great deal, but Joe Costello can add motivation and excitement back to an industry that's feeling tired.
One of their tools is a Datapath Compiler, which is one of the few commercial solutions for maximum performance datapath design. Other companies have come and gone (Arcadia is long gone; Arithmatica wasn't at DAC), but Micro Magic apparently has numerous real success stories. (Their customers seldom allow themselves to be named.)
I spoke to a few vendors in this space, but I wouldn't dare pretend to have a good grasp on where the field is at. Several journalists and bloggers are writing "now is the time for ESL synthesis", but I have yet to meet the designers using it or even enthusiastic to get into it. It's puzzling to me. There apparently are specific domains with considerable success, such as wireless and image or video processing. And there are specific geographic areas adopting it first, namely Japan. But for the mainstream ASIC designer, I don't yet see it catching on.
I liked what I heard in a brief visit with Imera, which develops hardware+software solutions to allow secure remote debug of software (e.g. EDA tools). In my work, there is constant antagonism between the EDA vendor, whose engineers claims they cannot debug their software beyond their walls versus the EDA customer, which doesn't want the "company jewels" of full-chip RTL or netlists to ftp over to the EDA vendor. Imera has solved the problem with a distributed debugger and networking solution that allows the R&D engineer to debug from the vendor side, while the EDA tool is running on the design data at the customer's site. Sounds like it would resolve the stalemate and allow us to get on with the problem-solving.
I had not attended DAC since 2006. It was a little disorienting because of all the changes in the industry and the conference itself. Attendance was way down from boom times. For the first time, I had an "exhibits only" pass, which allowed me to go up every day and visit the exhibits floor but not the technical program. After Free Monday, the floor was much less crowded, and it was a pleasure to walk right up to any vendor and get all my questions answered. One irritating practice of several vendors was to not have any open demos, but to require a one-hour appointment to be scheduled for a closed-door meeting. I found this quite inconvenient for any sort of spontaneous discovery, and as a result both vendors and I missed out on some worthwhile discussions.
I was glad I attended DAC. I obtained information that will help me in my job, and met old and new friends. I wish for the sake of the organizers and the exhibitors that attendance had been stronger, but the economy was a strong tide to fight. Let's hope that tide is turning and the 47th DAC in Anaheim will celebrate a growing vital EDA industry.
If you're at DAC and haven't yet overdosed on "Social Media", please stop by Tweet, Blog or News: How Do I Stay Current? this afternoon. I'll be on the panel, sharing ideas for how to wade into this trend in the most efficient way. Listen, ask questions, and say Hi.
Denali Software is a great supporter of DAC. They teamed up with Atrenta and Springsoft to start the I Love DAC program and provide dozens of complimentary Exhibits passes for the conference. They also ran good-natured competitions for EDA's Next Top Blogger and EDA's Community Superheroes. Congratulations to Karen Bartleson of Synopsys for winning the Top Blogger distinction, and Joy Matsumoto from Cadence for her great efforts to support charitable causes.
DAC begins its second full day in San Francisco, and I encourage you to take advantage of the opportunity. I was up there yesterday and found a great variety of vendors, panels, and other events to check out. In the morning, crowds were pretty sparse, but there was a definite pick-up in the afternoon. In particular, there was a lot of congestion around the prominent Synopsys booth, next to a well-visited Standards area.

That said, I'd encourage everyone to venture out beyond the comfort and safety of the big EDA vendors! If anything, I de-emphasize visits to the top vendors, because one can follow their announcements and arrange meetings any time of the year. But DAC is a unique opportunity to see a great variety of vendors, from the "second tier" specialist that you're not quite familiar with to the Mom & Pop startup that just rolled out their shingle for their first DAC. To make this discovery more purposeful, I flip through the Exhibitor descriptions in the DAC program and highlight the booths of companies that sound remotely interesting. That way, you can avoid wasting time by ping-ponging between North and South halls. Go for it!
On a lighter note, on Sunday I made my way to San Francisco for an EDAC reception. Before that, I explored Golden Gate Park (stunning!) and snapped a few pictures.

The next best thing to being at DAC is to watch the "tweets" posted by attendees--
Caltrain provides service on the San Francisco Peninsula. Here's their schedule. If you catch one of the "baby bullet" express trains, it's less than an hour from San Jose to San Francisco. Fares from San Jose are
| One Way | $7.75 |
| Day Pass | $15.50 |
From the Caltrain station in San Francisco, you'll need to get to Moscone Center. In previous years, DAC ran a shuttle for this, but I don't see any notice of it this year. You can either walk or take the city bus. It's only a one-mile walk, so I plan to try this and count the back and forth as my exercise for the week. Google has a nice map showing both the walking route and links to bus schedules, if you prefer. View Larger Map
As a pleasant surprise, there's quite a bit of activity and emerging excitement in the area of synthesis, just in time for this year's DAC.
Oasys Design Systems has come out of stealth mode with rather incredible performance claims.
It's exciting to hope for a revolution in synthesis. Put me in the "show-me" camp. It's (relatively) easy to meet 80% of what Design Compiler can do, but there are many features and tricks developed by DC over the years, making it a hard tool to displace. Synopsys has certainly seen strong competition, including from Ambit BuildGates (acquired by Cadence) and most recently by Get2Chip (now Cadence RTL Compiler). What often happens is not that king DC is overthrown, but that the competition lights a fire under Synopsys and their tools will improve at a much faster pace than market dominance would dictate.
What's interesting about Oasys are the tremendous claims about capacity and run time, and the emphasis on physical synthesis, combining logic synthesis with placement and optimization. The company also has impressive board members, including Sanjiv Kaul (former implementation GM at Synopsys) and, re-appearing to EDA after a long hiatus, Joe Costello (charismatic and successful former Cadence CEO).
For several years, EDA industry analyst Gary Smith has been calling for the ascent of ESL (Electronic System Level) design. He was already called an ESL evangelist back in 2006! It's been the next big thing for a while now. It seems to follow the industry's progression from transistors to gates to RTL, but RTL remains the mainstream design method.
In the context of design implementation, ESL implies synthesis at a more abstract level than RTL. This year, there appears to be considerably more buzz, and not just from Gary. See, for example, recent posts by John Cooley and Richard Goering.
Key players include
My apologies for any I've overlooked--I'm learning about this field. One point of concern is that there isn't a consensus on design language/dialect, which varies by vendor over C, C++, SystemC, and proprietary languages/extensions. That can impede adoption. It was Design Compiler that established the de facto standard for Verilog RTL synthesis subset, and this provided a common point for customers (and competitors) to converge on.
It's nice to see continued innovation in this critical area of IC design, and merits further investigation.
As most everyone is aware, the big conference in the chip design software world,
DAC, runs July 26-31 in San Francisco.
I'm looking forward to it and plan to be up there most days.
Some prognosticators have posted their "must-see" lists.
(Gary Smith, John Cooley
laying out the law for aspiring vendors) and there will be more to come.
Rather than calling out specific companies, I'll share some of technologies that I'll be looking to learn more about.
Update: check out Richard Goering's interview with EDA luminary Kurt Keutzer on this topic.
Don't believe everything you read.
There's an insightful behind the scenes exposé
on DeepChip about a technology web site that turns out to be a marketing venue for a group
of EDA start-ups.
Nothing wrong with that, but the disclosure of who's behind it took some digging and
questioning to tease out.
Of course, one would be naive to assume this doesn't happen elsewhere in the media. Even Mr. Cooley's beloved DeepChip, with its purported user-generated content, can be gamed. When you read a glowing endorsement of an EDA tool, ask yourself questions such as
Nothing beats the testimonial of someone you know and trust, other than your own hands-on evaluation.

Over the years, DAC has become more user friendly. The panels in particular are often informative and sometimes provocative. I find that I'm getting more and more out of DAC.
This year, there's an explicit "User Track" at the conference. I'd like to share a description of the User Track while presenting the first guest post on John's Semi-Blog. Please enjoy!

46th DAC New Initiatives ChairToday’s connected world makes it possible for you to work from everywhere. Yet, there’s only one place where you can learn how your peers successfully applied design tools to chip design and where you can exchange valuable experiences: the new User Track at this year’s DAC.
The three-day User Track features 40 presentations that run in parallel with regular technical sessions. Speakers include expert designers from Cisco, ClueLogic, Fujitsu, IBM, Infineon, Intel, Qualcomm, Samsung, STMicroelectronics, Sun, Texas Instruments, Virtutech, Xilinx and others.
Identifying Front-End Challenges
Power planning and verification continues to be hot. A team from NEC will detail an automated flow to pre-characterize the power consumption of a set of basic components starting from their behavioral description in C, down to their power estimation at the gate-level netlist. A team from Cisco will describe the use of a power noise analysis tool to analyze system power integrity. Engineers from Texas Instruments will illustrate how they used an EDA tool to integrate complex multi-power/voltage domain design. Intel engineers will present a flexible, high-level power management modeling and simulation framework for power architects. And, a team from STMicroelectronics and ST-Ericsson will outline an exploratory and refinement-based power planning system. Also, Intel engineers from India and Israel will offer a novel direction for using abstract executable models to verify power management protocols.
Tackling Backend Challenges:
In the Practical Physical Design session, a team from Intel will discuss how they tackle ECOs as late logic changes delay the process and register arrays occupy more than half of all transistors of modern designs. Qualcomm designers will describe how they build their semi-custom methodology and STMicroelectronics engineers will outline e how they use the IP-XACT standard from Spirit to enable IP reuse.
Accurate power supply and substrate noise analysis remains a challenge, and practitioners from Qualcomm, IBM, Samsung and Kobe University will show how they attack the problem. Texas Instrument designers will show how to analyze blocks for reuse in multiple metal stacks. Intel engineers will highlight their approach to assessing design feasibility early in the process to avoid problems later.
A team from Stanford University, Rambus and Netlogic describes a way to tackle analog reuse as it becomes as important as reuse is in digital design. A group from Cadence and several Taiwanese universities will describe their approach to integrate MEMs in mixed-signal designs. Engineers from NXP and Magwel tackled the problem of analyzing substrate noise and will present their results in 90nm process technology. With complex circuits often needing an integrated approach to physical and electrical verification, a team from SysDsoft and Mentor describes how they accomplished this on their designs.
In addition, join us for an Ice Cream Social Wednesday from 1:30pm-3pm where 42 posters will offer an opportunity for you to mingle with other EDA tool users.
Access to the User Track is included with the full-conference registration. Or, register separately for the User Track and get access to the keynotes, in addition to the User Track. For more details, visit: www.dac.com. We look forward to seeing you in San Francisco.

Not only is the video entertaining, but it's a bona fide piece of EDA history. It's also worthwhile to reflect on the promise of Frameworks, still unfulfilled in EDA: seamlessly integrated multi-vendor tool flows. Well, at least it's job security for CAD engineers.
And, at the party itself, watch the show and vote for EDA Idols!
John also posted that the very popular "Free Monday" deal is coming back as well. Here's what his email described:
From: Bob Gardner [bobg=user domain=edac.org]Hi, John,
Please inform your readers that EDAC has decided to sponsor the return of "Free Monday" to DAC this year. If they want to take advantage of this "Free Monday" registration, your readers must go to:
http://www.deepchip.com/FreeMonday.html
and complete all four pages of the registration. On the THIRD page they'll find a newly added "Free Monday Exhibits" option -- they MUST check this box to get this special registration.
On the forth page they should see a web receipt with their unique bar code confirmation on it. They must print this entire page.
To enter the DAC Exhibit Hall on Monday, July 27th, the engineer must present a paper copy of his/her entire bar code page to the Advance Registration desk located in the North Lobby of Moscone Center.
See you at DAC, John!

As for me, I've already paid my $50 for the all-DAC exhibits pass. See you there. The buzz for DAC is heating up, so watch for more blog posts before the conference.
Rajeev founded several significant EDA companies, was apparently out-manuvered in the board room at times, and is forthcoming with what he's learned about the EDA industry and building companies.
I glanced at a few presentations and was most surprised to see predictions of the resurgence of ASIC vendors (vs. today's popular "COT" model). I'm not sure I agree, but it makes a certain amount of sense. It takes a lot of tools, people, and expertise to implement 45 nanometer chips. The proposition is that if it is possible to cleanly hand off at RTL, then the chip designer can focus on functionality, and let an implementation house focus on the tricks and traps of nanometer-scale design closure. But that's a big if, to be confident that the hand-off is of a properly constrained and realizable design!
You could find kindred spirits of any interest available for text-based correspondence and enlightenment. I solved countless software problem (including both Windows and Linux) by searching through these groups. Who could forget groups like
Oh, and the flame wars! (I remember there was a character outraged over the Ottoman Empire who sought to cancel every post containing "turkey", which swept up Thanksgiving recipes, as well.)
The beginning of the end was when Web access took off, epitomized by "AOL newbies" pouring onto Usenet without regard to the collegial etiquette that previously existed. After AOL, there was overwhelming growth of users, which strained the scalability of worldwide discussion forums. Finally, the death knell: Spam. When I peek at Usenet groups today, they're full of the most crude and amateurish spam. It appears that posts are not run through filters as is all of our email, and this makes the noise/signal ratio unbearable.
R.I.P., Usenet. You were one of the forefathers of what we enjoy today through the Web, forums, IM, and social networking.
