Webinar: Synopsys on Clock Gating Verification with VC Formal

Webinar: Synopsys on Clock Gating Verification with VC Formal
by Bernard Murphy on 07-06-2017 at 12:00 pm
Categories: EDA, Events, Synopsys

Clock gating is arguably the mostly widely-used design method to reduce power since it is broadly applicable even when more sophisticated methods like power islands are ruled out. But this style can be fraught with hazards even for careful designers. When you start with a proven-correct logic design and add clock gating, the logic… Read More

Every SoC that connects to an analog sensor or device requires AMS (Analog Mixed-Signal) circuit simulation for design and verification, so this year at #54DAC the organizers at Synopsys hosted another informative AMS panel session over lunch time on Monday. What makes this kind of panel so refreshing is that the invited speakers… Read More

Synopsys PrimeTime PX, popularly known as PT-PX, is widely recognized as the gold standard for power signoff. Calculation is based on a final gate-level netlist reflecting final gate selections and either approximate interconnect parasitics or final parasitics based on the post-layout netlist. The only way to get more accurate… Read More

CCIX Protocol Push PCI Express 4.0 up to 25G

CCIX Protocol Push PCI Express 4.0 up to 25G

The CCIX consortium has developed the Cache Coherent Interconnect for Accelerators (X) protocol. The goal is to support cache coherency, allowing faster and more efficient sharing of memory between processors and accelerators, while utilizing PCIe 4.0 as transport layer. With Ethernet, PCI Express is certainly the most popular… Read More

Any sufficiently advanced technology is indistinguishable from magic, as the saying goes. Which is all very well when the purpose is entertainment or serving the arcane skills of a select priesthood, but it’s not a good way to grow a market. Then you want to dispel the magic aura, make the basic mechanics more accessible to a wider… Read More

Is ARC HS4xD Family More a CPU or DSP IP Core?

Is ARC HS4xD Family More a CPU or DSP IP Core?
by Eric Esteve on 06-02-2017 at 4:00 pm
Categories: IP, Synopsys

When I had to define the various IP categories (processor, analog & mixed-signal, wired interfaces, etc.) to build the Design IP Report, I scratched my head for a while about the processor main category: how to define the sub-categories? Not that long ago, it was easy to identify a CPU IP core and a DSP IP core. As of today, if a DSP… Read More

Webinar: Getting to Accurate Power Estimates Earlier and Faster

Webinar: Getting to Accurate Power Estimates Earlier and Faster
by Bernard Murphy on 05-24-2017 at 7:00 am
Categories: EDA, Events, Synopsys

Power has become a very important metric in modern designs – for mobile and IoT devices which must live on a battery charge for days or years, for datacenters where power costs can be as significant as capital costs, and for increasingly unavoidable regulatory reasons. But accurate power estimation on a design must start from an … Read More

CDC Verification for FPGA – Beyond the Basics

CDC Verification for FPGA – Beyond the Basics
by Bernard Murphy on 05-23-2017 at 12:00 pm
Categories: EDA, FPGA, Synopsys

FPGAs have become a lot more capable and a lot more powerful, more closely resembling SoCs than the glue-logic we once considered them to be. Look at any big FPGA – a Xilinx Zynq, an Intel/Altera Arria or a Microsemi SmartFusion; these devices are full-blown SoCs, functionally different from an ASIC SoC only in that some of the device… Read More

Building Better Digital Content Protection

Building Better Digital Content Protection

Categories: IP, Synopsys

Back in college my roommates figured out that the TV cable coax wire was still connected to our apartment. As a result, I was able to watch the Richard Pryor movie Silver Streak about 30 times without a cable box, however the screen was partially jumbled from the simple content protection used back then. This was possible by aggressively… Read More

The great thing about competition in free markets is that vendors are always pushing their products to find an edge. You the consumer don’t have to do much to take advantage of these advances (other than possibly paying for new options). You just sit back and watch the tool you use get faster and deliver better QoR. You may think that… Read More
