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

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
HLS – Major Improvement through Generations
I am a believer of continuous improvement in anything we do; it’s pleasant to see rapid innovation in technology these days, especially in semiconductor space – technology, design, tools, methodologies… Imagine a 100K gates up to 1M gates design running at a few hundred MHz frequency and at technology node in the range of .18 to … Read More
HLS Tools Coming into Limelight!
For about a decade I am looking forward to seeing more of system level design and verification including high level synthesis (HLS), virtual prototyping, and system modeling etc. to come in the main stream of SoC design. Although the progress has been slow, I see it accelerating as more and more tools address the typical pain points… Read More
Designing Hardware with C++ and its Advantages
Very recently, I was seeing intense discussions on the need for agile hardware development just like agile software and ideas were being sought from experts as well as individuals. While in software world it has already evolved, in hardware world it’s yet to see the shift in paradigm. My point is that the end goal of agile hardware… Read More
Expansion at Calypto through Real Value Addition in SoC Design
When we get the notion of expansion of a company, it always provides a positive picture about something good happening to boost that expansion. There can be several reasons for expansion such as merger & acquisition, formation of joint venture or partnership, large customer orders and so on. However, organic expansion which… Read More
Designing the Right Architecture Using HLS
With the advent of HLS tools, general notion which comes to mind is that okay, there’s an automated tool which can optimize your design description written in C++/SystemC and provide you a perfect RTL. In real life, it’s not so, any design description needs hardware designer’s expertise to adopt right algorithm and architecture… Read More
How to Reduce Maximum Power at RTL Stage?
Of course that reduction has to stay throughout the design cycle up to layout implementation and fabrication. Since the advent of high density, mega functionality SoC designs at advanced nodes and battery life critical devices played by our fingertips, the gap between SoC power requirement and actual SoC power has only increased.… Read More
Accelerating SoC Verification Through HLS
Once upon a time there was a struggle for verification completion of semiconductor designs at gate level. Today, beyond imagination, there is a struggle to verify a design with billions of gates at the RTL level which may never complete. The designs are large SoCs with complex architectures and several constraints of area, performance,… Read More
High Level Synthesis update from #51DAC
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
