Electro Static Discharge (ESD) is a fact of life for IC designs and has been ever since electronics were first created and then started failing because of sudden, large currents flowing through the design caused by human, processing or machine contact. It’s just too expensive to layout an IC today, fabricate it, test for … Read More

Power Modeling and Simulation of System Memory Subsystem
One great benefit of designing at the ESL level is the promise of power savings on the order of 40% to 70% compared to using an RTL approach. Since a typical SoC can contain a hierarchy of memory, this kind of power savings could be a critical factor in meeting PPA goals. To find out how an SoC designer could use such an ESL approach to power… Read More
Catching IC Manufacturing Defects With Slack-Based Transition Delay Testing
Test engineers are often the unsung heroes in the semiconductor world, because they have the tough job of deciding if each IC is good or bad, while taking the least amount of time on a tester and ensuring that the tests are actually finding and uncovering all manufacturing and process variation defects. Simple stuck-at fault models… Read More
Modeling and Analysis of Single Event Effects (SEE)
Single Event Effects (SEE) are important because we depend upon our consumer, industrial and aerospace products to work reliably. Protons, electrons, neutrons, or alpha particles may perturb the MOS or bipolar device operation in either a destructive or non-destructive fashion. Galactic cosmic rays are one source of these… Read More
An Approach to Clock Domain Crossing for SoC Designs
Blogger Pawan Fangaria wrote about Clock Domain Crossing(CDC) a few weeks ago, and so I followed up tonight and watched a webinarabout CDC presented by Ravindra Anejaof Atrenta. An RTL design engineer would ultimately want a CDC verification tool that offers:
- Fast throughput and thoroughness
- Ability to debug and fix the source
Analog FastSPICE Update at DAC
Tuesday night over dinner at DAC I was able to chat with Ravi Subramanian, CEO of Berkeley DA, recently acquired by Mentor Graphics back on March 21st. This acquisition provided Mentor with an Analog FastSPICE circuit simulator to round out its collection of simulators.… Read More
RTL Signoff Update from #51DAC
In the early days of Customer Owned Tooling (COT) the signoff was done at the GDS II, or physical level. Today, however we see the trend of RTL signoff instead because of the EDA tools and methodology available. At DACearlier this month I met with Piyush Sanchetiof Atrenta to get an update on what’s new with RTL signoff.… Read More
Virtual Prototype Update from #51DAC
EDA industry pundit Gary Smithhas been talking about the electronics industry adopting an ESL tool flow for decades, so it was my pleasure to speak with Bill Neifertof Carbon Design Systemsat DAC this month because his company has been offering both tools and models that enable a virtual prototyping design flow.… Read More
High Level Synthesis update from #51DAC
Every since Synopsys dominated the logic synthesis market in the 1980’s we’ve had something called HLS – High Level Synthesis, meaning something higher than what Design Compiler can understand as input. At DACthis year I met with Mark Milligan of Calypto to get an update on what’s new with HLS. I first… Read More
Standard Cell, IO and Hard IP Validation update
Every SoC team uses libraries of cells to get their new product to market quicker: Standard Cells, IO Cells and Hard IP blocks. One immediate question that comes to my mind is, “How clean are these cells?” Validating your cell libraries first makes sense, and will ensure that there are fewer surprises as your chip gets… Read More
