Peggy said EDA tools are overpriced? Huh! How about giving me a quality product that doesn't crash so often! Makes Microsoft Office look like mission-critical software. [a pet peeve of mine which I hope to expand on in a future post]

Keeping the Day Job
Dan Lyons, more famously known as Fake Steve Jobs, wrote Growing Rich by Blogging Is a High-Tech Fairy Tale for his "day job" at newsweek.com.
It gives insight and some figures on the financial opportunities for bloggers. To cut to the chase: there's not a lot of opportunity! Certainly that's not why I blog, though it's nice to imagine the claimed average earnings of $5,060 per year.
It also gave me more insight into Dan Lyons, the person. As often happens, I liked the "fantasy person" Fake Steve Jobs better. I was disappointed to read that getting rich was a big reason for his launching the Fake Steve Jobs blog, which I found absolutely hilarious. Mark me naive for wishing he just wanted to share his creative gift with all of us. You do have a humourous gift, Dan. May you find a way to re-launch it and make a good living while you're at it.

FREE Utility Grab-Bag
Therefore, I'm highlighting a few useful commands or utility packages that an engineer might use regularly. I plan to follow this up with a post on useful free EDA packages. My "go-to" utilities are
- screen
- think of it as "text VNC". lightweight and low bandwith. Hey, most of what we do in VNC is textual anyway, right?
- putty
- rock-solid terminal client to access *nix from Windows
- truecrypt
- free industrial-strength encryption. Because you'd hate to have your USB drive or notebook PC data fall into the wrong hands.
- xargs
- *nix command to process a list (e.g., of file names) piped from another command

Getting Kids Excited about Chip Design
I was at the San Jose Tech Museum of Innovation yesterday to see their US-exclusive Leonardo exhibit. It really drives home what a genius Leonardo da Vinci was. He seemed to know everything knowable as of 1500, and the exhibits make it clear that he was a god of mechanical engineering (among many things).
If he were around today, with what's available with electrical and electronic engineering, imagine what he would have created! Who is the da Vinci of our day?
Besides this featured exhibit, the kids I brought and I explored the other Current Exhibits. I was excited to find displays on semiconductor design and manufacturing in the Silicon Workshop.
The design section is sponsored by Cadence and the EDA Consortium, and has hands-on activities showing what I knew to be logic design and physical design. I was excited to explain to the children how a few simple logic gates could be interconnected to control what actions would start the model car, turn on its lights, etc. And I think they enjoyed it, too.
Ask me again in ten years whether this influenced the kids at all to pursue science or engineering. I think it is a good attempt. Props to Cadence and EDAC for creating this to show what we do and inspire the next generation.

AMD Cuts a Harbinger?
The story
AMD to slash 1,100 jobs, cut executive salaries (Reuters)
has variously been reported as "just a layoff", or, in this headline, layoffs + executive salary cuts. But if you read the article, the salary cuts apply to everyone who survives the layoff. Exempt employees, which includes engineers and other professionals, will get a 10% pay cut.
Ouch! People would prefer a cut to being laid off, but 10% could be quite a challenge for those who've been good consumers and not such good savers. I'm concerned that these measures will become more common as the economy continues to struggle.
As an aside, the article curiously mentions voluntary pay reduction measures for employees outside North America. What's a "voluntary pay reduction"? Does it mean "sacrifice for the greater good", or "volunteer or else something worse might befall you"?

Top 20 predictions for semis in 2009
Maybe rather than yet another blog post of 2008 review and 2009 predictions, I'll just flag provocative ones like EETimes.com's Top 20 predictions for semis in 2009 by Mark LaPedus.
Some of my favorite points:
That's a lot of quoting, but there's even more good stuff in the article. The author definitely "names names" of which companies may fail and which will prevail.

Important Technology Developments of 2008 - Seeking Alpha
Happy New Year, dear readers! This time of year, it's irresistable to look back over the last year, and perhaps venture some forecasts for the coming one. Before I try to put together my own list, here's a list of The 10 Most Important Technology Developments of 2008 that covers technology broadly (not just semiconductors).
Most of the technologies cited are still nascent. While the iPhone is already significant, it's going to be quite a while before we see memristors in our chips. And I'll have to go look up graphine, since I've never heard of that for chip fabrication.

Choice Careers
Would you advise smart young people to go into Engineering? It's a question our profession often ponders.
Consider the alternatives.
Why not use one's attention to detail to become an attorney?
Why not use one's mathematical prowess to go into finance?
Become a "rocket scientist", a "master of the universe".
I hadn't looked seriously at Wall Street careers, but the compensation described in
The Reckoning - On Wall Street, Bonuses, Not Profits, Were Real - Series - NYTimes.com
is truly staggering:
The bonanza redefined success for an entire generation. Graduates of top universities sought their fortunes in banking, rather than in careers like medicine, engineering or teaching. Wall Street worked its rookies hard, but it held out the promise of rich rewards. In college dorms, tales of 30-year-olds pulling down $5 million a year were legion.
Admittedly, now isn't the best moment to go into finance. Wall Street financiers are going to have to lay low for a while, lick their wounds, and make some pay for the Ponzi scheme(s) that will come out. But in the end, won't it come roaring back? From a monetary perspective, won't it always be more lucrative to be close to where money is changing hands, rather than cooped up in an R&D lab designing the next big thing? I'm not saying it's right, but that seems to be the way it is.

Last EDA Vendor Standing?
Man, there's some ugly financial results being reported by almost all EDA companies lately. Take a look at Sramana Mitra's financial review.
And poor LogicVision is facing a measly $10M takeover offer, as John Ford covers in Merry Christmas… We want your company
Ms. Mitra surveys the current situation of EDA companies in the provocatively titled EDA: Bring Costello Back?. The title of the post alludes to Cadence's vacancy at the top, of course. For those of you too young to remember, Joe Costello was the charismatic and highly energetic CEO of Cadence from its founding through 1997. It's fun to reminisce about EDA's heyday and colorful characters, but it's probably wishful thinking that he'd want to come back and try to revive Cadence's business.
Meanwhile, John Cooley has a list of 47 candidates for Cadence CEO. What do you think about that list? I get his point, that he strongly believes the new leader should be an EDA veteran. But 47 names? Too unfocused. It's almost like he's name-dropping all the EDA executives he knows.
In my opinion, the best candidate might be a proven CEO or top executive of an EDA start-up, or an autonomous General Manager of an EDA company division. The candidate should be strong technically and have a track record of managing and growing the business. Not "just a Sales guy", or some VP who dropped into the company after it was already up and running. Perhaps a founder of the company, with passion and real leadership. Let's hope they find a great leader, both for the industry and the sake of chip designers everywhere.
Let's hope we don't end up with one company dominating the industry. That would be insufferable, like Ernestine the Operator's (monopoly) Telephone Company
How To Be World Class
Amidst the constant news of the struggling macroeconomy and generally bleak news in EDA and related industries, it'd be a good idea to focus on doing something positive.
How To Be World Class is a brief review of the talked-about book Outliers, which I hope you'll find inspirational.

‘Golden’ timing signoff
Ruben Molina of Extreme DA has a well-written article, ‘Golden’ timing signoff – does it correlate to Spice?. Certainly, one cannot argue that we treat SPICE simulation results as "golden" (for a given set of PVT conditions). At the same time, device-level SPICE is a lot harder to work with than gate-level tools such as static timing analyzers. Therefore, as he says, designers looking to qualify a tool may take the easy way out and compare the new tool to the de facto standard, even if the accuracy of the standard tool isn't well understood. SPICE should be the arbiter.
I sometimes feel sorry for new tool vendors going against a well-established "gorilla". They design the fastest, most accurate tool that they can, and then find customers complaining that it doesn't match the idiosyncracies of older tools. To add insult to injury, the aspiring tool vendor may have to add in "compatibility mode" features that produce less accurate or less sensible results, just to correlate to the tool the want to displace.
This has happened in EDA for a long time. Remember when Cadence's Verilog-XL was THE simulation standard? Upstarts, including Chronologic with VCS, couldn't just implement the Verilog spec. Customers forced them to mimic every quirk of Verilog-XL. It was the arbiter, much to competitor's frustration.
In the case of timing tools, it behooves tool vendors to offer a qualification flow. For example, to compare to SPICE, the tool should be able to select timing paths, write out accurate & valid SPICE decks, and make it easy to run the simulations by pointing to the SPICE tool and library models. In this way, it lowers the barrier for customers to compare against the "right" standard, instead of the easy one.

Password Arms Race
I get the feeling that companies with customer web sites are viewing "password ridiculousness" as a measure of how valuable their site content is. Come on, it's just a knowledge base! If the user gets the password wrong after three tries, lock them out. Other than that, why make the password like a nuclear launch code?

Remote Software Debug?
I'm not a professional software engineer (just another Perl hacker), but this seems that it ought to be possible. I just don't know how to pull it off.
