Analog FastSPICE eXTreme

When Analog FastSPICE was first introduced in 2006 it changed the landscape for high performance SPICE simulation. During the last 14 years it has been used widely to verify advanced nanometer designs. Of course, since then the most advanced designs have progressed significantly, making verification even more difficult. Just… Read More

Mentor SerDes Simulation

Over the years SerDes (serializer/deserializer) based connections have proliferated into just about every connection within and among computing systems. Years ago, parallel interfaces were the most common method of moving data, but issues of signal integrity, synchronization and power simply became too much for the required… Read More

Mentor and Azure

Most EDA tools started out running on mainframe computers, then minicomputers, followed by workstations and finally desktop PCs running Linux. If your SoC design team is working on a big chip with over a billion transistors, then your company likely will use a compute farm to distribute some of the more demanding IC jobs over lots… Read More


Device Noise Analysis, What Not to Do for AMS IC Designs

Device Noise Analysis, What Not to Do for AMS IC Designs
by Daniel Payne on 07-24-2015 at 12:00 pm

AMS IC designers have a lot to think about when crafting transistor-level designs to meet specifications and schedules, so the most-used tool in their kit is the trusted SPICE or FastSPICE circuit simulator to help analyze timing, power, sensitivity and even device noise. I just did a Google search for “device noise analysisRead More

I’m looking forward to the 2013 TSMC Open Innovation Platform Ecosystem Forum to be held Oct. 1[SUP]st[/SUP] in San Jose. One paper in particular that has my attention is titled, “An Efficient and Accurate Sign-Off Simulation Methodology for High-Performance CMOS Image Sensors,” by Berkeley Design Automation & … Read More


CDNS V. BDA: Motion to Dismiss

CDNS V. BDA: Motion to Dismiss
by Paul McLellan on 05-02-2013 at 1:00 pm

The Cadence-BDA saga continues with Berkeley Design Automation today filing a motion to dismiss. You can read the full motion HERE. My previous blog “Cadence Sues Berkeley Design Automation” with 30+ comments is HERE.

The first problem BDA brings up is that the DMCA claim by Cadence is so vague that it doesn’t… Read More


Hot Topic – CMOS Image Sensor Verification!

Hot Topic – CMOS Image Sensor Verification!
by Daniel Nenni on 04-29-2013 at 7:30 pm

Mobile applications require CMOS image sensor devices that have a low signal-to-noise ratio (SNR), low power, small area, high resolution, high dynamic range, and high frame rate. CMOS image sensor imaging performance is noise limited requiring accurate noise analysis on the pixel array electronics and column readout circuitry.… 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

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
