Symphony Pro for mixed-signal verification

It’s the second day of DAC, and the announcements are coming in at a fast pace, so stay tuned to SemiWiki for all of the latest details. As a long-time SPICE user and industry follower, I’ve witnessed the progression as EDA vendors have connected their SPICE simulators to digital simulators, opening up a bigger world… Read More


How 16nm and 14nm FinFETs Require New SPICE Simulators

How 16nm and 14nm FinFETs Require New SPICE Simulators
by Daniel Payne on 02-07-2016 at 7:00 am

About 35 years ago the first commercial SPICE circuit simulators emerged and they were quickly put to work helping circuit designers predict the timing and power of 6um NMOS designs. Then we had to limit our circuit simulations to just hundreds of transistors and interconnect elements to fit into the RAM and complete simulation… 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


Transceiver Verification of a 20nm Altera FPGA Device

Transceiver Verification of a 20nm Altera FPGA Device
by Daniel Payne on 09-11-2014 at 6:00 pm

FPGA devices are a great way to drive silicon technology development because they contain both digital and analog IP, along with sophisticated IO cells. The highest performance IOs are transceivers, and Altera has recently designed the Arria 10 device family to include up to 96 transceivers, using a 20nm technology that can achieve… Read More


Analog FastSPICE AMS — Simple, Fast, nm-Accurate Mixed-Signal Verification

Analog FastSPICE AMS — Simple, Fast, nm-Accurate Mixed-Signal Verification
by Daniel Nenni on 11-12-2012 at 7:00 pm


Verification and AMS are top search terms on SemiWiki so clearly designers have a pressing need for fast and accurate verification of today’s mixed-signal SoCs that include massive digital blocks and precision analog/RF circuits. They need simulation performance to verify the mixed-signal functionality, and they need nanometer… Read More


A Brief History of SPICE

A Brief History of SPICE
by Daniel Payne on 08-10-2012 at 4:06 pm

SPICE is an acronym for Simulation Program with Integrated Circuit Emphasis and represents a class of EDA software used by circuit designers at the transistor-level to predict the timing, frequency, voltage, current or power of an IC or interconnect before fabrication.

In 1971 there was a tool called CANCER (Computer Analysis… Read More


Analog FastSPICE added to Tanner EDA

Analog FastSPICE added to Tanner EDA
by Daniel Payne on 05-24-2012 at 10:18 am

Last year when I visited Tanner EDA at DAC I heard about how they integrated the Analog FastSPICE circuit simulator from Berkeley DA.

This made sense to me because BDA has a good reputation for speeding up SPICE without compromising on accuracy, and Tanner users may want to mix and match tools from multiple EDA vendors.

This year they’ve… Read More
