EDACafe Weekly Review August 16th, 2012

In our latest blog entries, Synopsys mixed-signal customers talked about their verification flow. Those posts described known aspects of mixed-signal environment (such as for example behavioral modeling). I wanted to highlight today a slightly different usage of Synopsys mixed signal solution among some of our customers. Using performance and ease of use of CustomSim-VCS, DFT verification engineers are able to get a considerable speedup in their simulations.

Of course, when I am referring to DFT, I am not talking about Fourier Transform, but Design For Test 🙂

Rambus is one of those customers. Working closely with Synopsys, they presented a paper on this approach. The goal was to use CustomSim-VCS to drastically improve DFT  logic and timing verification cycle-time and coverage.

In this interview, Bing Chuang from Rambus and Sumit Vishwakarma  from Synopsys share their  insights about using CustomSim –VCS  for DFT Logic and Timing Verification, the flow they architected  and the improved coverage and performance they were able to get.

Mixed-signal Design: a new how-to guide from CDNS
August 15, 2012  by Peggy Aycinena

 

This week, Cadence announced availability of the 400-page Mixed-Signal Methodology Guide written by Jess Chen, Michael Henrie, Monte Mar, Mladen Nizic, et al, edited by EDA DesignLine’s Brian Baily.

Cadence says the book is targeted at both chip designers and CAD engineers, and “focuses on current and future advanced mixed-signal design challenges and solutions.” The company also says the book is “critically acclaimed and much anticipated,” which is a little confusing; if the book is much anticipated, how could it already be critically acclaimed?

Nonetheless, the availability of the book on Lulu.com – an on-demand self-publishing website – makes the text easy to purchase and reasonably priced: $69.00, marked down from $115 if you buy it by August 31st. The question is not one of price, however, but of usefulness: Where else are you going to get information on mixed-signal design if you want to get it out of a book?

If you go to Amazon, for instance, what can you find? Below is a small sampling of what’s currently available. Sorry for the tedious assignment, but if you scan through the contents of each book you’ll see there’s quite a bit of overlap, and there’s also quite a bit of differentiation. Looking at the first 4 selections on the list, and then comparing them to the 2012 Cadence publication, you may actually conclude that this new book by Chen et al is indeed bringing something very useful to the discussion of mixed-signal design, albeit with a focus on Cadence tools.
