How Fast (and accurate) is Your SPICE Circuit Simulator?

How Fast (and accurate) is Your SPICE Circuit Simulator?
by Daniel Payne on 12-06-2011 at 6:17 pm

In my dad’s generation they tweaked cars to become hotrods while in EDA today we have companies that tweak SPICE circuit simulators to become crowned speed champions. The perennial question though is, “How fast and accurate is my SPICE circuit simulator?”… Read More


Circuit Simulation and Ultra low-power IC Design at Toumaz

Circuit Simulation and Ultra low-power IC Design at Toumaz
by Daniel Payne on 10-06-2011 at 4:31 pm

I read about how Toumaz used the Analog Fast SPICE (AFS) tool from BDA and it sounded interesting so I setup a Skype call with Alan Wong in the UK last month to find out how they design their ultra low-power IC chips.


Interview

Q: Tell me about your IC design background.
A: I’ve been at Toumaz almost 8 years now and before that at Sony… Read More


AMS Verification: Speed versus Accuracy

AMS Verification: Speed versus Accuracy
by Daniel Nenni on 10-03-2011 at 9:16 pm

I spent Thursday Sept. 22 at the first nanometer Circuit Verification Forum, held at TechMart in Santa Clara. Hosted by Berkeley Design Automation (BDA), the forum was attended by 100+ people, with circuit designers dominating. I spoke with many attendees. They were seeking solutions to the hugely challenging problems they … Read More


When analog/RF/mixed-signal IC design meets nanometer CMOS geometries!

When analog/RF/mixed-signal IC design meets nanometer CMOS geometries!
by Daniel Nenni on 09-13-2011 at 9:22 am

In working with TSMC and GlobalFoundries on AMS design reference flows I have experienced first hand the increasing verification challenges of nanometer analog, RF, and mixed-signal circuits. Tools in this area have to be both silicon accurate and blindingly fast! Berkeley Design Automation is one of the key vendors in this … Read More

Nanometer Circuit Verification Forum
by Daniel Nenni on 08-29-2011 at 2:33 pm

Verifying circuits on advanced process nodes has always been difficult, and it’s no easier with today’s nanometer CMOS processes. There’s a great paradox in nanometer circuit design and verification. Designers achieve their greatest differentiation when they implement analog, mixed-signal, RF and custom … Read More

Intro
Simon Young, Product Marketing manager at BDA gave me an update at DAC last week on their circuit simulator, Analog Fast SPICE (AFS).

Notes

Quarterly release: 2011 Q2 now

Speed Improvements: Still 5 to 10X speed improvement over other SPICE tools

Multi-Threading – 2 to 4 X improvement using 4 to 8 cores.

Device Noise – three … Read More
