It's been several years since I've run SPICE myself, but I'm finding it increasingly needed even for a RTL/gate-level engineer. Could anyone recommend some really good SPICE books, which aren't just a reference but show you how to do things? You can post your recommendations and advice here as comments. The "things" I'd be most interested in doing would be characterizing digital standard cells and analyzing IC interconnect.
I looked at Amazon.com and didn't find a lot of books like this (no "SPICE for Dummies"?), but these two look interesting. Before I or my company spends a chunk of change, do you know these titles and how useful they are?
