Portable Stimulus Shines at DVCon

By tomacadence | 4 Mar 2017

For me, this week was almost entirely consumed with the Design and Verification Conference and Exhibition ( DVCon ) at the familiar DoubleTree in San Jose. The hotel has replaced its chandeliers with shiny new space-age fixtures, but otherwise, I felt at...

Bare Metal Tests and Hardware-Software Co-Verification

By tomacadence | 23 Jan 2017

One interesting question that arises from time to time is whether the Cadence® Perspec ™ System Verifier can verify software as well as hardware. The question is simple enough, but the answer is more complex. There are at least two versions of “yes...

Bugs, Problems, Issues, and Features

By tomacadence | 4 Jan 2017

There’s no better way to demonstrate the value of a verification tool than to find a killer bug in the customer’s design. When the verification engineer looks up from the screen and says, “Wow – we might never have found that!” we EDA vendors are equally...
