HLS Optimizations You Can't Do By Hand

By SeanDart | 10 May 2019

In my previous blog post , I talked about the Quality-of-Results (QoR) that are achievable using High-Level Synthesis tools like Stratus HLS and the fact that exploration of multiple RTLL architectures is often the feature that enables HLS users to beat hand-coded RTL flows in terms of QoR. That article raised the notion that "project schedule" is a critical factor when judging comparative QoR, and it often gets left...

2018 Annual HLS Survey Results

By dpursley | 13 Dec 2018

Earlier this year, we performed the annual high-level synthesis (HLS) industry survey to get an idea of the industry’s expectations of HLS. As in last year’s survey , approximately half of the responses were from current HLS users, and half were from non-users. This year’s anonymous survey focused on HLS usage and expectations. As usual, I’ll walk through the questions one by one below, but first let me give you what...

ECO with Stratus HLS and the Digital Implementation Flow

By dpursley | 12 Dec 2018

For years chip designers have dealt with ECO’s when their source code was written in RTL. But the move to high-level synthesis (HLS) means that their source code is now one step further removed from the gate level netlist. This naturally leaves a question, “What if I need an ECO on my Stratus project?” First and foremost, it’s important to understand that ECO’s are less common in the HLS flow. I’ll explain why in a...

QoR with High-Level Synthesis. Can it really be better than hand-coded RTL?

By SeanDart | 2 Aug 2018

Whenever we talk to potential customers about Stratus HLS , we usually mention that many users get better quality of results (QoR) with a Stratus HLS flow than they did simply writing RTL by hand. Often, we are greeted with looks of skepticism or downright disbelief. We are usually asked the honest question: Can Stratus HLS really achieve better QoR than we can get using traditional RTL coding? I assure you that...

A Decade of Building CODECs with High-Level Synthesis

By SeanDart | 9 Jul 2018

Over the past decade, we have seen a dramatic increase in the size of common video formats. Addressing this has required an evolution in the performance and complexity of video codecs, all the way from MPEG-2 to H.265. When designing hardware for these CODECs, high-level synthesis (HLS) has been a very common implementation tool of choice, due to the huge productivity gains provided by HLS and the ability of designers...

High-Level Synthesis: The Secret Is Out

By dpursley | 12 Jun 2018

Gone is the day when companies (our customers) kept their use of high-level synthesis (HLS) quiet, a secret advantage over their competitors. As HLS usage became more widespread, the secret is out , and now the HLS community is talking and sharing experiences with each other. Take CDNLive , for instance. This year, HLS discussions are happening at the CDNLive shows worldwide. Since it’s extremely unlikely any of you...

Wind of Change in Hardware Design

By dpursley | 21 Feb 2018

After months of freezing temperatures in Pittsburgh, a 78 degree wind hit me as I stepped out of the office yesterday. While I’m sure it will be cold again by the time this blog gets published, yesterday made me think about how things are changing. In the 2017 annual HLS survey , we confirmed that wireless is the fastest growing market segment for high-level synthesis (HLS). That wasn’t much of a surprise, because...

Functional Correctness—The Forgotten Benefit of HLS

By dpursley | 6 Nov 2017

I like to ask questions, because you learn a lot that way. In fact, I did a survey earlier this year and learned that high-level synthesis users’ experiences are exceeding the non-users’ expectations, and that HLS is being used for a wider variety of design types than even I knew. Recently I asked one of my favorite questions, and got an answer I truly didn’t expect. My favorite question to ask new HLS users: “What...

Faster and Smarter

By MeeraC | 5 Oct 2017

At the Cadence VIP dinner at Korea CDNLive last month, Paul Cunningham spoke about the state of the EDA industry, especially in the digital and signoff world. It all comes down to the productivity gap between the design diversity and complexity rising faster than the design schedules and other limited resources. This is our fundamental challenge. To overcome those challenges, designers must approach the challenge...

Designing for Low Power… Begin at the Beginning

By dpursley | 1 May 2017

So you have your RTL written, and it’s time to optimize to reduce power. If that’s your plan, you are likely leaving power on the table. It’s not that you can’t get a lot of savings with existing RTL synthesis tools (you certainly can!), but the biggest bang for the buck comes from early design decisions. Next time… start sooner! In fact, experts (not me, real experts ) estimate that optimal architectural (pre...

Making Hardware Design Great Again in 2017

By dpursley | 22 Feb 2017

Ok, I admit it… that title is a blatant attempt to grab your attention. But it should also make you think. As a hardware designer, is your job great? Is it what you thought you’d be doing when you decided to become a designer? Is it, dare I say, fun? Or, like I hear so many times especially from those designing embedded integrated circuits , are you too bogged down in the muck of cranking out hardware implementations...
