Thanks for the article, Jim, and Mike for the comment. Indeed also for me after 30 plus years of being in the semiconductor business, custom IC design still is an extremely interesting challenge. Best, Thomas at topvu.com.
Very interesting article.
"Optimal Sampling and Design-Specific corners" - reminds me of one of the ideas I came up with while I was at Antrim. There is a patent for this that belongs to Cadence now.
My notion was to enable synthesis of analog circuits by extracting only the most critical parameters that are strongly correlated to an objective specification. Once the parameter-to-spec relationship was extracted, it was converted to a behavioral model, eliminating the need for full circuit simulation when the parameters, or the spec, was changed.
I'm wondering if this approach would lend itself to what you referred to as "Optimal Sampling and Design-Specific corners"
