If you think of Xilinx the word that immediately comes to mind is FPGA. After all they were one of the pioneers of the space. FPGAs are a means of implementing hardware, and the main implementation methodology is RTL-based. This compares to writing software and compiling it for a microprocessor, which is the main software implementation… 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
Designing an IDCT for H.265 using High Level Synthesis
Math geeks know all about Inverse Discrete Cosine Transforms (IDCT) and a popular use is in the hardware architecture of High Efficiency Video Coding (HEVC), also known as H.265, the new video compression standard and widely used in consumer and industrial video devices. You could go about hand-coding RTL to create an IDCT function,… Read More
High Level Synthesis. Are We There Yet?
High level synthesis (HLS) seems to have been part of the backdrop of design automation for so long that it seems to be one of those things that nobody notices any more. But it has also crept up on people and gone from interesting technology to keep an eye on to getting genuine adoption. The first commercial product in the space was behavioral… Read More
NVIDIA and Qualcomm Talk about High Level Synthesis, Samsung on Low Power for Mobile
Since 1978 I’ve seen many trends in the semiconductor design world: transistor-level IC design, gate-level design, RTL coding, High Level Synthesis (HLS) and IP re-use. We’ve witnessed the growth in design productivity enabling chips starting with just thousands of transistor all the way up to billions of transistors… Read More
Verifying the RTL Coming out of a High-Level Synthesis Tool
With High-Level Synthesis (HLS) the first benefit that comes to my mind is reduced design time, because coding with C or SystemC is more efficient than low-level RTL code. What I’ve just learned is that there’s another benefit, a reduction in the amount of functional simulation required. One HLS customer was able … Read More
Xilinx’s 16nm UltraScale+ FPGA is Revolutionary
Well a very belated Happy New Year dear reader. I must admit, it has been a very long winter and it has caused the Miller’s to rethink this vital question. “What in the world are we doing living in NY”. So we are moving, and hopefully this is my last ‘real’ winter as we headed down south. To perhaps alleviate some of the winter blues from … Read More
High Level Synthesis Gets Stronger
High Level Synthesis (HLS) tools have been around for at least two decades now, and you may recall that about one year ago Cadence acquired Forte. The whole promise of HLS is to provide more design and verification productivity by raising the design abstraction from RTL code up to SystemC, C or C++ code. With any acquisition it is natural… Read More
Shorten the Learning Curve for High Level Synthesis
When chip designers moved from a gate-level design methodology to coding with RTL there was a learning curve involved, and the same thing happens when you move from RTL to High Level Synthesis (HLS) using C++ or SystemC coding. One great shortcut to this learning curve is the use of pre-defined library functions. I just heard about… Read More
Xilinx the EDA Company
Like you I cannot believe 2015 is upon us. 15 years ago I remember the Y2K panic. I remember watching the news and noticed the liberal media (they were liberal back then too) just waiting for the first fail somewhere. Ended up like Geraldo at the opening of Al Capone’s Vault. Remember that one? As I persist on with this word salad may I … Read More
