Configuration Environment is Make-or-Break for IC Verification

Configuration Environment is Make-or-Break for IC Verification
by Tom Simon on 12-10-2020 at 10:00 am

IC Verification Environment

All semiconductor design work today rests on the three-legged stool of Foundries, EDA Tools and Designers. Close collaboration between the three make possible the successful completion of ever more complex designs, especially those at advanced nodes. Perhaps one of the most critical intersections of all three is during physical… Read More

Smoother MATLAB to HLS Flow

Smoother MATLAB to HLS Flow

A better design path from MATLAB 1 min

It hard to imagine design of a complex signal processing or computer vision application starting somewhere other than in MATLAB. Prove out the algorithm in MATLAB, then re-model in Simulink, to move closer to hardware. First probably an architectural model, using MATLAB library functions to prove out behavior of the larger system.… Read More

PCIe Verification IP

PCI Express (PCIe) has become an important communication element in a wide range of systems. It is used to connect networking, storage, FPGA and GPGPU boards to servers and desktop systems. It has progressed a long way from its initial parallel bus format. Its evolution to a serial point to point configuration has been accompanied… Read More


The Practitioners View of DAC – Design, IP and Embedded

The Practitioners View of DAC – Design, IP and Embedded
by Mike Gianfagna on 12-07-2020 at 10:00 am

The First DAC

Next year will mark the 58th year for the Design Automation Conference. It’s hard to wrap your head around the fact this event dates back to 1964, when rock ‘n roll was new, cars were big and computers were even bigger. In its early days, the event was called the Design Automation Workshop. Pictured above is the cover of the very first… Read More


Curvilinear FPD Layout and Schematics

Curvilinear FPD Layout and Schematics

layout ladder min

You are likely reading this blog using a Flat Panel Display (FPD), because they are so ubiquitous in our desktop, tablet and smart phone devices. Today I’m following up from a previous article. A quick recap of the unique design flow for FPD is shown below:

What follows is the second part of a Q&A discussion with Chen Zhao… Read More


A Fast Checking Methodology for Power/Ground Shorts

A Fast Checking Methodology for Power/Ground Shorts
by Tom Dillinger on 12-01-2020 at 10:00 am

Figure 4

The most vexing problem for physical implementation engineers is debugging errors due to power-ground “shorts”, as reported by the layout-versus-schematic (LVS) physical verification flow.  The number of polygons associated with each individual grid is large – an erroneous connection between grids results in a huge number… Read More


ML plus formal for analog. Innovation in Verification

ML plus formal for analog. Innovation in Verification
by Bernard Murphy on 11-30-2020 at 6:00 am

innovation min

Can machine learning be combined with formal to find rare failures in analog designs? ML plus formal for analog – neat! Paul Cunningham (GM, Verification at Cadence), Jim Hogan and I continue our series on research ideas. Here an idea from analog simulation sampling. Feel free to comment.

The Innovation

This month’s pick… Read More


Cadence is Making Floorplanning Easier by Changing the Rules

Cadence is Making Floorplanning Easier by Changing the Rules
by Mike Gianfagna on 11-25-2020 at 8:00 am

Mixed placement floorplan

SoC designs are getting more complex, resulting in a higher level of difficulty to get anything done. This trend is well-known. What I want to focus on here is how to deal with the issue of complexity. There are many approaches to taming this problem — faster algorithms for one, and improved algorithm efficiency or the ability to run… Read More


EDA Tool Support for GAA Process Designs

EDA Tool Support for GAA Process Designs
by Daniel Nenni on 11-23-2020 at 6:00 am

GAA FinFET

With the announcement of early PDK availability for the 3nm GAA process node, designers are extremely interested in the characteristics of the new “gate-all-around” transistor structure and how it compares to the existing FinFET device.  The GAA transistor has been denoted as a (horizontal) nanowire or nanosheet.

I will talk… Read More
