Closing Coverage in HLS

Closing Coverage in HLS
by Alex Tan on 10-08-2018 at 12:00 pm

Coverage is a common metric with many manifestation. During the ‘90s, both fault and test coverage were mainstream DFT (Design For Testability) terminologies used to indicate the percentage of a design being observable or tested. Its pervasive use was then spilled over into other design segments such as code coverage, formal… Read More


High-Level Synthesis for Automotive SoCs

High-Level Synthesis for Automotive SoCs
by Mitch Heins on 09-15-2017 at 7:00 am

Some of the world’s most complex Systems-on-Chip (SoCs) are being developed for automotive applications. These SoCs have heterogeneous architectures with a variety of processors and accelerators that do real-time image processing for assisted and autonomous driving applications. The Bosch Visiontec team, in Sophia Antipolis,… Read More


Xilinx is a Software Company

Xilinx is a Software Company
by Paul McLellan on 09-10-2015 at 7:00 am

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


High Level Synthesis. Are We There Yet?

High Level Synthesis. Are We There Yet?
by Paul McLellan on 06-16-2015 at 7:00 am

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

NVIDIA and Qualcomm Talk about High Level Synthesis, Samsung on Low Power for Mobile
by Daniel Payne on 05-31-2015 at 4:00 pm

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


Shorten the Learning Curve for High Level Synthesis

Shorten the Learning Curve for High Level Synthesis
by Daniel Payne on 01-27-2015 at 4:30 pm

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


High Level Synthesis update from #51DAC

High Level Synthesis update from #51DAC
by Daniel Payne on 06-27-2014 at 8:00 pm

Every since Synopsys dominated the logic synthesis market in the 1980’s we’ve had something called HLS – High Level Synthesis, meaning something higher than what Design Compiler can understand as input. At DACthis year I met with Mark Milligan of Calypto to get an update on what’s new with HLS. I first… Read More


Calypto: the View From the Top

Calypto: the View From the Top
by Paul McLellan on 03-05-2014 at 10:37 pm

At DVCon today I talked to Sanjiv Kaul, the CEO of Calypto. Just as a reminder, Calypto have 3 products, SLEC (sequential logical equivalence checking, also called sequential formal verification), PowerPro (sequential RTL level power reduction) and Catapult High Level Synthesis (that they took over from Mentor in 2011 in a complicated… Read More


6 reasons Synopsys covets C/C++ static analysis

6 reasons Synopsys covets C/C++ static analysis
by Don Dingee on 02-20-2014 at 5:00 pm

By now, you’ve probably seen the news on Synopsys acquiring Coverity, and a few thoughts from our own Paul McLellan and Daniel Payne in commentary, who I respect deeply – and I’m guessing there are many like them out there in the EDA community scratching their heads a little or a lot at this. I’m not from corporate, but I am here… Read More


Cadence Acquires Forte

Cadence Acquires Forte
by Paul McLellan on 02-05-2014 at 4:46 pm


Cadence today announced that it is acquiring Forte Design Systems. Forte was the earliest of the high-level synthesis (HLS) companies. There were earlier products. Synopsys had Behavioral Compiler and Cadence had a product whose name I forget (Visual Architect?), but both products were too early and were canceled. Cadence … Read More
