It’s been the case most of the time that until we hit a bottleneck situation, we do not realize that our focus is not at the right spot. Similar is the case with power analysis at the SoC level. Power has become equally if not more important than the functionality and other parameters of an SoC, and therefore has to be verified earlier … 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
How PowerArtist Interfaces with Emulators
Last month in DAC I could see some of the top innovations in the EDA world. EDA is a key enabler for advances in semiconductor designs. Among a number of innovations worth mentioning (about which I blogged just after DAC), the integration of Mentor’s Veloce with ANSYS’ PowerArtist for power analysis of live applications caught my… Read More
Power Management Gets Tricky in IP Driven World
Today, an SoC can have multiple instances of an IP and also instances of many different IPs from different vendors. Every instance of an IP can work in a separate mode and requires a dedicated power arrangement which may only be formalized at the implementation stage. The power intent, if specified earlier, will need to be re-generated… Read More
What’s New in Functional Verification Debug
We often think of EDA vendors competing with each other and using proprietary data formats to make it difficult for users to mix and match tools, or even create efficient flows of tools. At the recent DAC event in San Francisco I was pleasantly surprised to hear that two EDA vendors decided to cooperate instead of create incompatible… Read More
Predicting Lifetime of Analog ICs
With the increase of transistors per unit area, high density interconnects and manufacturing variability at lower nodes, the electronic devices have become more vulnerable to failures. The devices that operate under extreme conditions such as automotive devices that operate at high temperatures need to be robust enough to… Read More
The Best Conversations You Missed at #52DAC!
The CEO Fireside Chats were my very favorite part of #52DAC. Dr. Walden Rhines, Lip-Bu Tan, and Dr. Aart de Geus are heroes of the EDA industry, absolutely. I saw all three Fireside Chats and the one word that I’m left with is INSPIRED! … Read More
Why silicon photonics and 2.5D design go together
Silicon photonics is one of the upstart “More than Moore” technologies designed to enable the next generation of high-performance devices. Photonic design is the art of moving and transforming signals in the form of photons, allowing the message to literally travel at the speed of light, and bringing the promise of significant… Read More
Automate those voltage-dependent DRC checks!
Because IC design and verification never gets simpler, verification engineers now have to comply with voltage-dependent DRC (VD-DRC) rules. What does this term mean, and what new challenges does it bring to the DRC task? I’d like to share what I learned during another water-cooler conversation with Dina Medhat, senior technical… Read More
Will those IO pad rings pass foundry muster?
I was talking recently to Dina Medhat, a senior technical marketing engineer at Mentor, about, of all things, IO rings. It has not occurred to me that verifying that your IO rings comply with foundry rules presents new challenges.
IO ring checking isn’t new, nor is it unique to advanced IC process nodes. However, the same forces of… Read More
