The demand for information is growing at an unprecedented rate. Our insatiable appetite for communication, computing and downloading, is driving this demand. With emerging technologies, such as cloud computing and the internet of things, not to mention the 300 hours of video being loaded to YouTube every minute, this trend … Read More

FPGA Prototyping: From Homebrew to Integrated Solutions
Years ago, when FPGA prototyping started, there were no solutions that you could go out and buy and everything was created as a one-off: buy some FPGAs or an FPGA-based board, and put it all together. It was a lot of effort, nobody really knew in advance how long it would take, there was very limited visibility for debug and the whole … Read More
All Models Are Wrong, Some Are Useful
“All models are wrong, some are useful.” This remark is attributed to the statistician George Box who used it as the section heading in a paper published in 1976.
Just for fun I looked up a few semiconductor statistics from 1976. Total capital spending was $238M in Japan and $306M in US and…that’s it, there was nobody else back then … Read More
Mongoose: The Making of Samsung’s Custom CPU Core
Samsung is seemingly ready to move to a new milestone in its brief but exciting system-on-chip (SoC) history: a custom CPU core codenamed Mongoose. It’s going to be based on ARMv8 instruction set and is expected to outperform the Exynos 7420 application processor that Samsung unveiled this year. There are some media reports… Read More
Thermal Reliability and Power Integrity for IC Design
When I designed DRAM chips at Intel back in the 1970’s we didn’t really know what the die temperature would be before taping out silicon, instead we waited for packaged parts to come back and then did our thermal measurements. IC designers today don’t have that luxury of taping out their new SoC without having … Read More
Replacing the British Museum Algorithm
In principle, one way to address variation is to do simulations at lots of PVT corners. In practice, most of this simulation is wasted since it adds no new information, and even so, important corners will get missed. This is what Sifuei Ku of Microsemi calls the British Museum Algorithm. You walk everywhere. And if you don’t walk to… Read More
Moving up Verification to Scenario Driven Methodology
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
Explore Your Interconnect the ICScape Way
One of the surprises at DAC for ICScape was to be listed on Gary Smith’s list of companies to see. Surprised, since ICScape had never presented their products to him. They were listed under design debug. They don’t have a single product that really falls under that description, but rather a family of tools under the ICExplorer… Read More
Congratulations Dr. Walden C. Rhines!
A funny thing happened at the Design Automation Conference last June in San Francisco. I was browsing the Kaufman award winner mug shots in the EDAC booth and noticed that Wally Rhines was NOT a winner. You can see them HERE. Immediately in disbelief I said to myself: Self, how can this be? Joe Costello, Aart de Geus, and some other guys… Read More
