Verification complexity and volume has always been on the rise, taking significant amount of time, human, and compute resources. There are multiple techniques such as simulation, emulation, FPGA prototyping, formal verification, post-silicon testing, and so on which gain prominence in different situations and at different… Read More
What’s the Difference between Emulation and Prototyping?
Increasing system complexity requires constant focus on the optimal verification methodology. Verification environments incorporate a mix of: transaction-based stimulus and response monitors, (pseudo-)random testcase generation, and ultimately, system firmware and software. RTL statement and assertion coverage… Read More
Adding NAND Flash Can Be Tricky
As consumers, we take NAND flash memory for granted. It has worked its way into a vast array of products. These include USB drives, SD cards, wearables, IoT devices, tablets, phones and increasingly SSD’s for computer systems. From the outside the magic of flash memory seems quite simple, but we have to remember that this is a technology… Read More
A New Unified Power Solution at All Levels
When situation demands, multiple solutions appear with a slight lag of time. Similar is the story with estimating and optimizing power at SoC level. In the SoC era, power has become a critical criterion long ago, and there are tools available for power analysis and optimization. However, with more mobile and IoT (Internet of Things)… Read More
Cadence 2015 Q2 Results
Let’s start by getting the financial stuff out of the way. Revenue was $416 million; non-GAAP operating margin was 28%; non-GAAP EPS was $0.27; and operating cash flow was $122 million (up at lot, it was just $47M in Q1 and $69M in Q2 of 2014).
The thing that the financial types are most interested in are the changes to Cadence’s… Read More
How Emulation Enables Complex Power Intent Modeling
As the number of CPU, GPU, and IP is growing in an SoC, power management is becoming more and more a complex task in itself. A single tool or methodology may not be enough for complete power management and verification of an SoC. In an SoC, there can be multiple modes of operations involving hardware and software interactions, different… Read More
Tackling Layout Gradient Effects in 16 nm FinFET using Layout Automation
My first exposure to automating IC layout was back in the 1980’s at Intel where I coded a layout compiler to auto-generate about 6% of a graphics processor chip. The need to use automation for IC layout continues today, and with the advent of FinFET technology there are some new challenges like layout gradient effects that … 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
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
Next Generation Formal Technology to Boost Verification
With growing complexities and sizes of SoCs, verification has become a key challenge for design closure. There isn’t a single methodology that can provide complete verification closure for an SoC. Moreover creation of verification environment including hardware, software, testbench and testcases requires significant … Read More
