Addressing Power at Architectural and RTL Levels

Addressing Power at Architectural and RTL Levels
by Paul McLellan on 11-03-2013 at 4:30 pm

Major power reductions are possible by reducing power at the RTL and system levels, and not just at the gate and physical level. In fact, as is so often the case in design, changes can have much more impact when done at the higher level, even given that at that point in the design there is less accurate feedback about changes. Later the… Read More


Using HLS to Turbocharge Verification

Using HLS to Turbocharge Verification
by Paul McLellan on 10-16-2013 at 8:23 am

One of the benefits of using high-level synthesis is obviously the ease of writing some algorithms in SystemC since it is at a higher level than RTL (that’s why we call it high-level synthesis!). But a second benefit is at the verification level. Since a lot of the verification gets done at the SystemC level, less needs to be done at … Read More


What Applications Implement Best with High Level Synthesis?

What Applications Implement Best with High Level Synthesis?
by Daniel Payne on 07-26-2013 at 3:12 pm

RTL coding using languages like Verilog and VHDL have been around since the 1980’s and for almost as long a time we’ve been hearing about High Level Synthesis, or HLS that allows an SoC designer to code above the RTL level where you code at the algorithm level. The most popular HLS languages today are C, C++ and SystemC.… Read More


The fixed and the finite: QoR in FPGAs

The fixed and the finite: QoR in FPGAs
by Don Dingee on 07-22-2013 at 1:00 pm

There is an intriguingly amorphous term in FPGA design circles lately: Quality of Results, or QoR. Fitting a design in an FPGA is just the start – is a design optimal in real estate, throughput, power consumption, and IP reuse? Paradoxically, as FPGAs get bigger and take on bigger signal processing problems, QoR has become a larger… Read More


Calypto 2013 Report

Calypto 2013 Report
by Paul McLellan on 07-05-2013 at 5:48 am

Each year Calypto runs a survey of end-users. This year’s survey and report has two parts, power reduction and high level synthesis (HLS).

The topics covered are:

  • survey methodology and demographics
  • top methods used to reduce power
  • engineering time spent on specfiic RTL tasks to reduce power
  • plans to deploy RTL power reduction

Forte Rises
by Randy Smith on 04-23-2013 at 3:00 am

Over the past few months there has been a bit of back-and-forth concerning the 2012 market data indicating that Forte Designs Systems had taken over the top spot (by revenue) in the high-level synthesis (HLS) market (see stories hereand here). Having worked in this segment for Synfora as VP of Marketing, and as a consultant to AutoESL,… Read More


Mentor catapults Calypto

Mentor catapults Calypto
by Paul McLellan on 08-26-2011 at 10:36 am

Mentor has transferred its Catapult (high level synthesis) product line, including the people, to Calypto. Terms were not disclosed but apparently it is a non-cash deal. Calypto gets the product line. Mentor gets a big chunk of ownership of Calypto. So maybe the right way to look at this is as a partial acquisition of Calypto.

It … Read More
