Analog IC Verification – A Different Approach

Analog IC Verification – A Different Approach
by Daniel Payne on 05-04-2013 at 5:33 pm

Analog design seems to suffer from a huge gap when it comes to testing and verification. While some of this gap is natural – after all, often the only way to verify whether a particular design is working is to look at actual simulation waveforms – it still seems like a lot can be done to bring process into this sphere of the… Read More

Analog and Mixed-Signal (AMS) designers are facing more challenges than ever, so where can they go to get some relief? One place is a half-day seminar scheduled for May 16th in Bridgewater, New Jersey. SemiWiki has teamed up with Tanner EDA, Abbot Labs and SoftMEMS to present topics of:

  • True collaborative design enabled through

A Programmable Electrical Rule Checker

A Programmable Electrical Rule Checker
by Daniel Payne on 04-29-2013 at 11:21 pm

IC designers involved with physical design are familiar with acronyms like DRC (Design Rule Check), LVS (Layout Versus Schematic) and DFM (Design For Manufacturing), but how would you go about checking for compliance with ESD (Electro Static Discharge) rules? You may be able to kludge something together with your DRC tool and… Read More


Challenges of 20nm IC Design

Challenges of 20nm IC Design
by Daniel Payne on 04-29-2013 at 11:38 am

Designing at the 20nm node is harder than at 28nm, mostly because of the lithography and process variability challenges that in turn require changes to EDA tools and mask making. The attraction of 20nm design is realizing SoCs with 20 billion transistors. Saleem Haider from Synopsys spoke with me last week to review how Synopsys… Read More


10 to 100X faster HDL Simulation Speeds

10 to 100X faster HDL Simulation Speeds
by Daniel Payne on 04-24-2013 at 10:44 am

Speed, capacity, accuracy – these are the three major EDA tool metrics that we pay attention to and that enable us to design and verify an SoC. Talk to any design or verification engineer and ask if they are satisfied with the time that it takes to simulate their latest design, or to verify that it meets spec and is functionally… Read More


Variation-aware IC Design

Variation-aware IC Design
by Daniel Payne on 04-15-2013 at 4:18 pm

We’ve blogged before about Layout Dependent Effects (LDE) on SemiWiki and how it further complicates the IC design and layout process, especially at 28nm and lower nodes because the IC layout starts to change the MOS device performance. There’s an interesting webinarfrom Cadence on Variation-aware IC Design, … Read More


Two New TSMC-Cadence Webinars for Advanced Node Design

Two New TSMC-Cadence Webinars for Advanced Node Design
by Daniel Payne on 04-15-2013 at 3:43 pm

Foundries and EDA vendors are cooperating at increasing levels of technical intimacy as we head to the 20nm and lower nodes. Cadence has a strong position in the EDA tools used for IC design and layout of custom and AMS (Analog Mixed-Signal) designs. They have created a series of webinars to highlight the design challenges and new… Read More


SoC Power Integrity Challenges

SoC Power Integrity Challenges
by Daniel Payne on 04-08-2013 at 4:46 pm

At DAC in 2012 I visited a few dozen EDA companies and blogged 32 articles, however I didn’t get to see what Apache Design (now a subsidiary of ANSYS) had to say. I did have 20 minutes today to watch their latest video on SoC Power Integrity Challenges and decided to share what I learned. If you want to watch the video at Tech Online,… Read More


RTL Restructuring

RTL Restructuring
by Daniel Payne on 04-04-2013 at 2:34 pm

Hierarchical IC design has been around since the dawn of electronics, and every SoC design today will use hierarchy for both the physical and logical descriptions. During the physical implementation of an SoC you will likely run into EDA tool limits that require a re-structure of the hierarchy. This re-partitioning will cause… Read More
