70% of today’s ASIC and SoC designs are being prototyped on FPGAs. Everybody knows that. But, did you know that automating the process of converting what could be thousands of ASIC “golden” files into FPGA-friendly versions can mean big savings in a large design?… Read More
Designing Power Management ICs
With all the focus in design on SoCs in the latest sexy process (Hi-K Metal Gate! FinFETs!) it is easy to forget all the other chips that go into a system. When we say “system on a chip” there are actually very few systems that really get everything onto a single chip. One of the big areas that usually cannot go on the latest… Read More
How to Design an LTE Modem
Designing an LTE modem is an interesting case study in architectural and system level design because it is pretty much on the limit of what is possible in a current process node such as 28nm. I talked to Johannes Stahl of Synopsys about how you would accomplish this with the Synopsys suite of system level tools. He is the first to admit… Read More
Test Compression and Hierarchy at ITC
The International Test Conference (ITC) is this week in Anaheim and I’ve just learned what’s new at Synopsys with test compression and hierarchy. Last week I spoke with Robert Ruiz and Sandeep Kaushik of Synopsys by phone to get the latest scoop. There are two big product announcements today that cover:… Read More
LSI’s Experience With Formality Ultra
LSI is an early adopter of Formality Ultra, Synopsys’s tool for improving the entire ECO flow. I already wrote about the basic capability of the tool here. ECOs are changes that come very late in the design cycle, after place and route has already been “nearly” completed. They occur either due to last minute spec… Read More
More to the story than bigger FPGA-based prototyping
Still not convinced on the value of FPGA-based prototyping systems, or using older technology? I’ve been trying to find the story beyond just bigger, badder FPGAs in a box that you pour RTL into – and found some hints in a webinar on the Synopsys HAPS-70 from earlier this year.… Read More
Why Adopt Hierarchical Test for SoC Designs
IC designers have been creating with hierarchy for years to better manage large design sizes, however for the test world the concept of hierarchy and emerging standards is a bit newer. TSMC and Synopsys jointly created a webinarthat addresses hierarchical test, so I’ve attended it this week and summarized my findings here.… Read More
♫ IMG Sitting on the DOK of the Bay…Closin’ Timin’
Scott Fitzgerald is supposed to have said “the rich are not like other people” to Ernest Hemingway (he didn’t). In the same way, processors are not like other blocks, and not because they have more gates (they don’t). However, special approaches to optimizing processors are important because the clock… Read More
Debugging Verification Constraints
In his DAC keynote last year (2012) Mike Mueller of ARM compared how much CPU was required to verify the first ARM versus one of the latest ARM Cortex CPUs. Of course the newer CPU is hundreds of times larger than the first ARM but the amount of verification required was millions of times as much, requiring ARM to construct their own datacenter… Read More
The fixed and the finite: QoR in FPGAs
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
