Synopsys hosted a lunch panel on Tuesday of DAC this year, in which verification leaders from Intel, Qualcomm, Wave Computing, NXP and AMD talked about how they are using Synopsys verification technologies. Panelists covered multiple domains but the big takeaway for me was their full-throated endorsement of the ZeBu emulation… Read More
A Functional Safety Primer for FPGA – and the Rest of Us
Once in a while I come across a vendor-developed webinar which is so generally useful it deserves to be shared beyond the confines of sponsored sites. I don’t consider this spamming – if you choose you can ignore the vendor-specific part of the webinar and still derive significant value from the rest. In this instance, the topic is… Read More
Checking Clock Gating Equivalence the Easy Way
Synopsys just delivered a Webinar on using the sequential equivalence app (SEQ) in their VC Formal product to check that clock-gating didn’t mess up the functional intent of your RTL. This webinar is one in a series on VC Formal, designed to highlight the wide range of capabilities Synopsys has to offer in formal verification. They… Read More
Webinar: Synopsys on Clock Gating Verification with VC Formal
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
ARM, Infineon, Synopsys, SK Hynix talk AMS Simulation
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
Accurate Power Sooner
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
An InFormal Chat
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
Webinar: Getting to Accurate Power Estimates Earlier and Faster
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
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
Polishing Parallelism
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
