I’ve written several articles on High-Level Synthesis (HLS), designing in C, C++ or SystemC, then synthesizing to RTL. There is unquestionable appeal to the concept. A higher level of abstraction enables a function to be described in less lines of code (LOC). Which immediately offers higher productivity and implies less bugs… Read More

I wrote recently about Siemens EDA’s philosophy on designing quality in from the outset, rather than trying to verify it in. The first step is moving up the level of abstraction for design. They mentioned the advantages of HLS in this respect and I refined that to “for DSP-centric applications”. A Stanford group recently presented… Read More

A better design path from MATLAB 1 min

It hard to imagine design of a complex signal processing or computer vision application starting somewhere other than in MATLAB. Prove out the algorithm in MATLAB, then re-model in Simulink, to move closer to hardware. First probably an architectural model, using MATLAB library functions to prove out behavior of the larger system.… Read More

Presenters took a trip down memory lane at DAC this year by having a panel discussion on HLS (High Level Synthesis) spanning from 1974 to 2020, and that time period aligns with when I first graduated from the University of Minnesota in 1978, starting chip design at Intel, then later transitioning into EDA companies by 1986.

HLS PPA results

Last week Mentor hosted a virtual event on designing an AI accelerator with HLS, integrating it together with an Arm Corstone SSE-200 platform and characterizing/optimizing for performance and power. Though in some ways a recap of earlier presentations, there were some added insights in this session, particularly in characterizing… Read More

The DVCon conference and exhibition finished up in California just as the impact of the COVID-19 pandemic was ramping up in March, but at least they finished the conference by altering the schedule a bit. Umesh Sisodia, CEO at CircuitSutra Technologies presented at DVCON on the topic, Using High-Level Synthesis to Migrate OpenRead More

Custom AI acceleration continues to gather steam. In the cloud, Alibaba has launched its own custom accelerator, following Amazon and Google. Facebook is in the game too and Microsoft has a significant stake in Graphcore. Intel/Mobileye have a strong lock on edge AI in cars and wireless infrastructure builders are adding AI capabilities… Read More

dvcon 2020

Learning is a never-ending process for design and verification engineers, so outside of reading SemiWiki you likely want to attend at least a few events per year to keep updated, learn something new, attend a workshop, or even present something that has made your IC project work much better than before. Sure, DAC is always a great… Read More

SLEC verification

Formal verification has made significant inroads in RTL and gate-level verification because it provides complementary strengths to conventional dynamic verification methods; using both provides higher levels of coverage and confidence in the correctness of an implementation. I haven’t heard as much about formal use in … Read More


Webinar: From HLS Component to a Working Design

Webinar: From HLS Component to a Working Design
by Daniel Payne on 10-15-2019 at 10:00 am

Overview

Complex algorithms do not exist in a vacuum. After HLS is used to create an RTL component, to be useful, it needs to be integrated into a larger system. This means connecting it to other components, a processor, and even software. Once integrated, the system needs to be verified. The verification of the complete environment… Read More
