Design complexities in reset, like everything else in big SoC designs, has become incredibly complex, for all sorts of reasons. Long, long ago reset was something you just did once, when you turned the power on. Turn on, then hold reset for some amount of time until everything is in a known starting state, and off you go. Nice and simple.… Read More


Design Perspectives on Intermittent Faults

Design Perspectives on Intermittent Faults

Faults

Bugs are an inescapable reality in any but the most trivial designs and usually trace back to very deterministic causes – a misunderstanding of the intended spec or an incompletely thought-through implementation of some feature, either way leading to reliably reproducible failure under the right circumstances. You run diagnostics,… Read More


Low Power Verification Shifting Left

Low Power Verification Shifting Left
by Bernard Murphy on 05-08-2018 at 11:00 pm

I normally think of shift left as a way to move functional verification earlier in design, to compress the overall design cycle. But it can also make sense in other contexts, one particularly important example being power intent verification.

If you know anything about power intent, you know that it affects pretty much all aspects… Read More
