Over 40 customers have benchmarked Analog FastSPICE (AFS) on over 150 circuits versus probably every simulator out there in the last 10 months. AFS consistently beats every simulator by at least 5x when true full SPICE accuracy is the standard. Our accuracy standard is very exacting. If a customer identifies any discrepancy between Analog FastSPICE and their traditional SPICE simulator, our first step is to tighten the accuracy on both simulators. More times than not the traditional SPICE simulator waveforms move to the AFS results. Designers are amazed and immediately start wondering about their current simulator. If a discrepancy remains after setting very tight tolerances, we debug it until we find the source. We can take this approach and deliver these results in all cases because we solve the original device equations. If it is a bug in AFS, we fix it and deliver a fully regression-tested release generally within a week or two.

Most of Berkeley Design Automation’s early customers are Japanese companies because consumer IC suppliers were extremely concerned about PLL noise. Our first product was the world’s first (and still only) closed-loop, non-approximate PLL noise analyzer – called PLL Noise Analyzer (PNA). We focused that product on the Japanese market (where we have always had direct sales, BTW). Since Japanese semiconductor companies are notoriously exacting, our first 10 customers compared PNA results directly to silicon (because no other simulator can do this analysis). PNA delivers absolute accuracy to silicon to ~3dB. Running the PLL through a series of settings in silicon and PNA to “wash” out the modeling inaccuracies, PNA consistently tracks silicon to within ~1dB, i.e., if the tool says your PLL noise is getting better (or worse), then that’s what is really happening.

Berkeley Design Automation released PNA about 2 years ago with our transient engine (now Analog FastSPICE) and our RF engine (now RF FastSPICE) under-the-hood. By taking this approach we were able to prove and mature these two engines before taking them to the general market as standalone tools that work on any type of circuit. Our original PNA customers are now all Analog FastSPICE and RF FastSPICE customers as well. We announced Analog FastSPICE and RF FastSPICE at DAC last year and have had an incredible level of interest worldwide. We are rapidly signing up and announcing new customers including most recently Spansion, Atheros, Newport Media, and LG Electronics. You can expect to see many additional new customer announcements in the coming weeks and months.

Whew. Sorry for the long response, but sometimes the short answers do not give a complete picture. Thanks for your well wishes. Stop by and see us at DAC if you are there.
