GDSII and LEF min

For IC designs there are many data formats used throughout the logical and physical design process, and one of those file formats is called LEF, an acronym for Library Exchange Format, created by Tangent, an early EDA company with Place and Route tools that was acquired by Cadence way back in March 1989. LEF generation times can become… Read More


Cadence adds a new Fast SPICE Circuit Simulator

SPICE spectrum. Fast SPICE

In the early years of Cadence their growth was bolstered through many well-timed acquisitions, however over the last several years I’ve noticed a distinctively different trend where they have internally developed EDA tools. I had a Zoom call with Jay Madiraju from Cadence, who markets their newly announced Fast SPICE … Read More

The annual Siemens Digital Industries Software user group event was held virtually on May 26th, which made it easy to attend from my home office, although selecting from the list of speakers was a challenge, because they offered 475 sessions, wow. My focus is EDA, so I listened to Joseph Sawicki, the Executive Vice President, IC … Read More

fractal CrossFire min

We’re living in an era of good growth for semiconductor design companies, and it’s no secret that each new SoC that comes along contains hundreds of IP blocks, so IP design re-use is just an accepted way of getting to market more quickly with lower risks. But how do we really know that all of the new IP is really correct? … Read More

Accellera FSWG min

I’ve written before about how the automotive industry adheres to functional safety (FS) as defined in the ISO 26262 standard, along with other SemiWiki bloggers. That standard certainly defines the What part of FS, however it doesn’t mandate how you meet the standard, what tools you should be using, file formats … Read More

fault injection state space min

I love to read articles about autonomous vehicles and the eventual goal of reaching level 5, Full Automation, mostly because of the daunting engineering challenges in achieving this feat and all of the technology used in the process. The auto industry already has a defined safety requirements standard called ISO 26262, and one… Read More


Formal Verification Approach Continues to Grow

Formal Verification Approach Continues to Grow

formal history min

After a few decades of watching formal verification techniques being applied to SoC designs, it  certainly continues to be a growth market for EDA vendors. In the first decades from 1970-1990 the earliest forms of formal tools emerged at technical conferences, typically written by University students earning their Ph.D.s, … Read More

Engineers love to optimize their designs, but that implies that there are models and stimulus to automate the process.  Process engineers have TCAD tools, circuit designers have SPICE for circuit simulation, logic designers have gate-level simulators, RTL designers use logic simulation, but what is there for the system architects… Read More

power intent checks min

My first transistor-level IC design job was with Intel, doing DRAM designs by shrinking the layout to a smaller process node, and it also required running lots of SPICE runs with manually extracted parasitics to verify that everything was operating OK, meeting the access time specifications and power requirements across PVT … Read More

Defacto SoC Compiler

I read the semiconductor press, LinkedIn and social media (Twitter, Facebook) every morning along with an RSS feed that I setup, staying current on everything related to using EDA tools to make the task of SoC design a bit easier for design teams. A recent press release announced a tool called SoC Compiler, so my curiosity was piqued… Read More
