Virtualizing ICE

Virtualizing ICE
by Bernard Murphy on 07-25-2017 at 7:00 am

The defining characteristic of In-Circuit-Emulation (ICE) has been that the emulator is connected to real circuitry – a storage device perhaps, and PCIe or Ethernet interfaces. The advantage is that you can test your emulated model against real traffic and responses, rather than an interface model which may not fully capture… Read More


Webinar: Ansys on Multi-Physics PDN Optimization for 16/7nm

Webinar: Ansys on Multi-Physics PDN Optimization for 16/7nm
by Bernard Murphy on 07-22-2017 at 12:00 pm

On the off-chance you missed my previous pieces on this topic, at these dimensions conventional margin-based analysis becomes unreasonably pessimistic and it is necessary to analyze multiple dimensions together. People who build aircraft engines, turbines and other complex systems have known this for quite a long time. You… Read More


IP Diligence

IP Diligence
by Bernard Murphy on 07-20-2017 at 12:00 pm

I hinted earlier that Consensia would introduce at DAC their comprehensive approach to IP management across the enterprise, which they call DelphIP (oracle of Delphi, applied to IP). I talked with Dave Noble, VP BizDev at Consensia to understand where this fits in the design lifecycle.


IP management means a lot of different things.… Read More


Why Ansys bought CLKDA

Why Ansys bought CLKDA
by Bernard Murphy on 07-18-2017 at 7:00 am

Skipping over debates about what exactly changed hands in this transaction, what interests me is the technical motivation since I’m familiar with solutions at both companies. Of course, I can construct my own high-level rationalization, but I wanted to hear from the insiders, so I pestered Vic Kulkarni (VP and Chief Strategist)… Read More


Checking Clock Gating Equivalence the Easy Way

Checking Clock Gating Equivalence the Easy Way
by Bernard Murphy on 07-14-2017 at 7:00 am

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


Rob Bates on Safety and ISO26262

Rob Bates on Safety and ISO26262
by Bernard Murphy on 07-12-2017 at 7:00 am

Most of us would agree that safety is important in transportation and most of us know that in automotive electronics this means ISO26262 compliance. But, except for the experts, the details don’t make for an especially gripping read. I thought it would be interesting to get behind the process to better understand the motivation,… Read More


Cadence Explores Smarter Verification

Cadence Explores Smarter Verification
by Bernard Murphy on 07-10-2017 at 7:00 am

Verification as an effectively unbounded problem will always stir debate on ways to improve. A natural response is to put heavy emphasis on making existing methods faster and more seamless. That’s certainly part of continuous improvement but sometimes we also need to step back and ask the bigger questions – what is sufficient … Read More


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

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


Safety EDA

Safety EDA
by Bernard Murphy on 06-23-2017 at 7:00 am

It takes courage and perhaps even a little insanity to start a new EDA venture these days – unless you have a decently differentiated value proposition in a hot market. One company that caught my eye, Austemper, seems to measure up to these standards (though I can’t speak to the insanity part). They offer EDA tooling specifically… Read More


Can AI be Conscious?

Can AI be Conscious?
by Bernard Murphy on 06-21-2017 at 7:00 am

A little self-indulgence for the season, to lighten the relentless diet of DAC updates. I found a recent Wired article based on a TED talk on consciousness. The speaker drew a conclusion that consciousness was not something that could ever be captured in a machine and was a unique capability of living creatures (or at least humans).… Read More
