My first DAC was in 1987 so I’ve seen our industry expand greatly over the years, and I expect that #57DAC on July 19-23, 2020 in SFO to be another exciting event to attend for semiconductor professionals from around the globe. What makes DAC so compelling for me to visit are the people, exhibitors, panel discussions, technical… Read More

Analog IC design across PVT conditions, something new
Transistor-level design for full-custom and analog circuits has long been a way for IC design companies to get the absolute best performance out of silicon and keep ahead of the competition. One challenge to circuit designers is meeting all of the specs across all Process, Voltage and Temperature (PVT) corners, so that silicon… Read More
Approaches for EM, IR and Thermal Analysis of ICs
As an engineer I’ve learned how to trade off using various EDA tools based on the accuracy requirements and the time available to complete a project. EDA vendors have been offering software tools to help us with reliability concerns like EM, IR drop and thermal analysis for several years now. Last week I attended a webinar … Read More
Why is Low Frequency Noise Measurement for ICs Such a Big Deal?
Even digital designers need to be aware of how noise impacts their circuits because most clocked designs today use a Phase Locked Loop (PLL) block which contains a circuit called a Voltage Controlled Oscillator (VCO) that is quite sensitive in operation to the effects of noise and process variation. As process node scaling continues… Read More
Three Steps for Custom IC Design Migration and Optimization
Popular companies designing smart phones, CPUs, GPUs and Memory components all employ teams of custom IC designers to create the highest performance chips that are as small as possible, and at the lowest costs. How do they go about doing custom IC design migration and optimization when moving from one process node to another one?… Read More
Low Frequency Noise Challenges IC Designs
AMS and RF IC designers have known for years that their circuits are sensitive to noise, because if you amplify noise on an input source to an amplifier circuit then your chip can start to produce wrong answers. Even digital SoC designers need to start taking notice because every SoC is filled with SRAM IP blocks, and at each shrinking… Read More
IC Designers talk about 28nm to 7nm challenges at #53DAC
IC design challenges are different at advanced nodes like 7nm, so to learn more about the topic I attended a panel luncheon at DAC sponsored by Cadence. The moderator was both funny and technically astute, quite the rare combination, so kudos to Professor Rob Rutenbar, a former Neolinear guy now at the University of Illinois. Panelists… Read More
Custom IC Design Flow with OpenAccess
Imagine being able to use any combination of EDA vendor tools for schematic capture, SPICE circuit simulation, layout editing, place & route, DRC, LVS and extraction. On the foundry side, how about creating just a single Process Development Kit (PDK), instead of vendor-specific kits. Well, this is the basic premise of a recent… Read More
IC Design and OpenAccess
EDA vendors have long used proprietary file and database formats to keep their users locked into their specific tool flow and keep any competitors from sharing in the IC design process. Along the way the actual users of EDA tools have often requested and helped to create interoperable flows so that they could mix and match multiple… Read More
Device Noise Analysis, What Not to Do for AMS IC Designs
AMS IC designers have a lot to think about when crafting transistor-level designs to meet specifications and schedules, so the most-used tool in their kit is the trusted SPICE or FastSPICE circuit simulator to help analyze timing, power, sensitivity and even device noise. I just did a Google search for “device noise analysis… Read More
