Carbon Design Systems – Secret of Success

Carbon Design Systems – Secret of Success
by Pawan Fangaria on 02-19-2014 at 11:00 am


Last week, after learning from the press releaseof Carbonabout its rocking sustained growth with record-breaking revenue and a thumping 46% increase in bookings, I was interested to know some more details about what drives Carbon to such an amazing performance in an EDA market that is generally prone to growth of a few percentage… Read More


Happy Birthday Xilinx

Happy Birthday Xilinx
by Luke Miller on 02-14-2014 at 4:00 pm

I have never done this before, wished a company happy birthday. So here goes, Happy Birthday Xilinx! How does it feel to be 30? Looking good eh? Signing up for AARP? My family and I just sang and had cake and ice cream. They did look at me like I was nuts when I set a place at the table for a Xilinx FPGA. In all seriousness, over the years Xilinx… 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


Xilinx’s Mixed Signal FPGA

Xilinx’s Mixed Signal FPGA
by Luke Miller on 01-28-2014 at 10:00 am

Something in all the Xilinx chatter of UltraScale 20nm, 16nm, having massive amounts of Gigabit transceivers, DSP blocks, RAM, HLS, Rapid Design Closure gets lost… and that is Xilinx’s ability for Mixed Signals. I do not mean when you are talking with the wife (Remember Listen!), but a wonderful block that lives within… Read More


SLEC is Not LEC

SLEC is Not LEC
by Paul McLellan on 12-20-2013 at 3:00 pm

One of the questions that Calypto is asked all the time is what is the difference between sequential logical equivalence checking (SLEC) and logical equivalence checking (LEC).

LEC is the type of equivalence checking that has been around for 20 years, although like all EDA technologies gradually getting more powerful. LEC is … Read More


Xilinx Pulls Back the 20nm UltraScale Curtain

Xilinx Pulls Back the 20nm UltraScale Curtain
by Luke Miller on 12-12-2013 at 10:00 am

This week Xilinx has announced that “The Xilinx 20nm All Programmable UltraScale™ portfolio is now available with detailed device tables, product documentation, design tools and methodology support.”

Do you know what 20nm is? It’s small, tiny. Think about it this way, as I just learned today that one nanometer is about as long… Read More


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


Xilinx’s Vivado HLS Will Float Your FPGA

Xilinx’s Vivado HLS Will Float Your FPGA
by Luke Miller on 09-23-2013 at 8:30 pm

Very rarely does the FPGA designer, especially with respect to RADAR, think of the FPGA as a floating point processor. Just to be sure I asked my 6 year old and she agreed. But you know what, the Xilinx FPGAs float. Go try it, order some up and fill up the tub.

Anyways I purpose a duel to the avid VHDL coder. I want you to design me a Sine(x) … Read More


Verifying Hardware at the C-level

Verifying Hardware at the C-level
by Paul McLellan on 09-09-2013 at 2:25 pm

As more people adopt high-level synthesis (HLS) they start to worry about what is the best design flow to be using. This is especially so for verification since it forms such a large part of the effort on a modern SoC. The more people rely on HLS for producing their RTL from C, the more they realize they had better do a good job of verifying… Read More
