Creating Plug-and-Play IP Networks in Large SoCs with IEEE P1687 (IJTAG)

Creating Plug-and-Play IP Networks in Large SoCs with IEEE P1687 (IJTAG)
by glforte on 11-14-2012 at 2:15 pm

Until now, the integration and testing of IP blocks used in large SOCs has been a manual, time consuming design effort. A new standard called IEEE P1687 (or “IJTAG”) for IP plug-and-play integration is emerging to simplify these tasks. EDA tools are also emerging to support the new standard. Last week mentor announcedTessent IJTAG,… Read More


IJTAG, Testing Large SoCs

IJTAG, Testing Large SoCs
by Paul McLellan on 11-08-2012 at 5:57 pm

Test is the Rodney Dangerfield of EDA, it doesn’t get any respect. All designs need to be tested but somehow synthesis, routing, analog layout and the rest are the sexy areas. In my spoof all purpose EDA keynote address I even dissed it:You are short on time so slip in a quick mention of manufacturing test. Who knows anything … Read More

Most of us live perfectly good lives without distinction, fame, or note. Others rack up the honors, filling their walls and resumes with recognition of their brilliance. Like Dr. Janusz Rajski.

Rajski is the director of engineering for the test products at Mentor Graphics, an IEEE Fellow, and the inventor of embedded deterministic… Read More

Our EDA industry loves three letter acronyms so credit the same industry for creating a five letter acronym CoWoS. Two weeks ago TSMC announced tape-out of their first CoWoS test chip integrating with JEDEC Wide I/O mobile DRAM interface, making me interested enough to read more about it. At the recent TSMC Open Innovation Platform… Read More

Model Driven Development
by Paul McLellan on 10-25-2012 at 5:50 pm

Mentor has a webinar on Model Driven Development (MDD) for Systems Engineering, presented by Bill Chown. It is actually the first of 15 webinars. This first one is just over 30 minutes long and I assume the others will be too. The webinar focuses on embedded system development, which historically has largely been validated using… Read More


TSMC dilemma: Cadence, Mentor or Synopsys?

TSMC dilemma: Cadence, Mentor or Synopsys?
by Eric Esteve on 10-18-2012 at 4:49 am

Looking at the Press Release (PR) flow, it was interesting to see how TSMC has solved a communication dilemma. At first, let’s precise that #1 Silicon foundry has to work with each of the big three EDA companies. As a foundry, you don’t want to lose any customer, and then you support every major design flow. Choosing another strategy… Read More


High Frequency Analysis of IC Layouts

High Frequency Analysis of IC Layouts
by Daniel Payne on 10-03-2012 at 12:26 pm

IC designers of passive devices often use empirical approaches to perform High Frequency Analysis (HFA), however there is at least one new approach being offered by Mentor Graphics using a tool flow of:

Automating Complex Circuit Checking Tasks

Automating Complex Circuit Checking Tasks
by SStalnaker on 09-20-2012 at 7:24 pm

By Hend Wagieh, Mentor Graphics

At advanced IC technology nodes, circuit designers are now encountering problems such as reduced voltage supply headroom, increased wiring parasitic resistance (Rp) and capacitance (Cp), more restrictive electromigration (EM) rules, latch-up, and electrostatic discharge (ESD) damage,… Read More


Wiring Harness Design

Wiring Harness Design
by Paul McLellan on 09-04-2012 at 5:18 pm

In 2003 Mentor acquired a company doing wiring harness design. Being a semiconductor guy this wasn’t an area I’d had much to do with. But more than most semiconductor people I expect.

But back when I was an undergraduate, I had worked as a programmer for a subsidiary of Philips called Unicam that made a huge range of spectrometers… Read More


A Brief History of Mentor Graphics

A Brief History of Mentor Graphics
by Beth Martin on 08-20-2012 at 11:00 pm

In 1981, Pac-Man was sweeping the nation, the first space shuttle launched, and a small group of engineers in Oregon started not only a new company (Mentor Graphics), but an entirely new industry, electronic design automation (EDA).


Mentor founders Tom Bruggere, Gerry Langeler, and Dave Moffenbeier left Tektronix with a great… Read More
