FlexMesh min

With the increasing density of electronics in product enclosures, combined with a broad range of operating frequencies, designers must be cognizant of the issues associated with the radiation and coupling of electromagnetic energy.  The interference between different elements of the design may result in coupling noise-induced… Read More


Calibre DFM Adds Bidirectional DEF Integration

Calibre DFM Adds Bidirectional DEF Integration

Siemens EDA DFM flow

GDS and LEF/DEF each came about to support data exchange in different types of design flows, custom layout and place & route respectively. GDS (or stream format) was first created in the late 1970s to support the first generation of custom IC layout tools, such as Calma’s GDSII system. Of course, the GDS format has been updated… Read More

The Question That Has Guided My Analog Mixed Signal Career

I remember it like it was yesterday. I was sitting at lunch with good friend Scott Santandrea, explaining my struggles to get traction with the sales channel for the Analog to Digital Converter product line I was managing. My business line had been spending a lot of resources developing high-performance 24-bit delta sigma and 20-bit

2020 Retrospective. Innovation in Verification

2020 Retrospective. Innovation in Verification
by Bernard Murphy on 01-20-2021 at 6:00 am

innovation min

Paul Cunningham (GM, Verification at Cadence), Jim Hogan and I launched our series on Innovation in Verification at the beginning of last year. We wanted to explore basic innovations and new directions researchers are taking for hardware and system verification. Even we were surprised to find how rich a seam we had tapped. We plan… Read More


Automotive SoCs Need Reset Domain Crossing Checks

Automotive SoCs Need Reset Domain Crossing Checks
by Tom Simon on 01-19-2021 at 6:00 am

reset domain crossing verification

When the number of clock domain crossings (CDCs) in SoCs proliferated it readily became apparent that traditional verification methods were not well suited to ensuring that they were properly handled in the design. This led to the creation of new methods and tools to check for correct interfaces between domains. Now, in automotive… Read More

Siemens EDA is Applying Machine Learning to Back End Wafer Processing Simulation

There’s a lot to unpack in the title of this post. First, Siemens EDA is the new name for Mentor, a Siemens Business. The organization continues to operate as part of Siemens Digital Industries Software.  The organization has released a white paper that describes research done with the American University of Armenia. The work examines… Read More

CDC, Low Power Verification. Mentor and Cypress Perspective

CDC, Low Power Verification. Mentor and Cypress Perspective
by Bernard Murphy on 01-13-2021 at 6:00 am

CDC Low Power

Clock domain crossing (CDC) analysis is unavoidable in any modern SoC design and is challenging enough to verify in its own right. CDC plus low power management adds more excitement to your verification task. I wrote on this topic for another solution provider last year. This time I want to intro an interesting twist on the problem,… Read More
