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
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
A Most Significant Man
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
Chip On Wafer On Substrate (CoWoS)
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
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?
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
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:
- Device detection and extraction with Calibre LVS and Calibre PERC
- Interconnect RLC extraction with Calibre xRC, Calibre xACT-3D
Automating Complex Circuit Checking Tasks
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
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
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
