Multicore systems working with shared memory must support a well-defined model for consistency of thread accesses to that memory. There are multiple possible consistency models. Can a design team run memory consistency checks at RTL? Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur,… Read More
A processor ISA provides an abstraction against which to verify an implementation. We look here at a paper extending this concept to accelerators, for verification of how these interact with processors and software. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys… Read More
Roots of trust can’t prevent attacks through side-channels which monitor total power consumption or execution timing. Correcting weakness to such attacks requires pre-silicon vulnerability analysis. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO)… Read More
Instrumenting post-silicon validation is not a new idea but here’s a twist. Using (pre-silicon) emulation to choose debug observation structures to instrument in-silicon. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO) and I continue our series on research… Read More
Leveraging neural nets and CR testing isn’t as simple as we first thought. But is that the last word in combining these two techniques? Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO) and I continue our series on research ideas. As always, feedback welcome.… Read More
Fuzzing is to software verification what randomization is hardware verification. Can a fuzzing approach improve hardware security testing? Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO) and I continue our series on research ideas. As always, feedback… Read More
Agile methods in hardware design are becoming topical again. What does this mean for verification? Paul Cunningham (GM, Verification at Cadence) and I continue our series on research ideas. We’re also honored this month to welcome Raúl Camposano to our blog as a very distinguished replacement for Jim Hogan. As always, feedback… Read More
Paul Cunningham, CVP and GM of the System Verification Group at Cadence gave the afternoon Keynote on Tuesday at DVCon and doubled down on his verification-throughput message. At the end of the day, what matters most to us in verification is the number of bugs found and fixed per dollar per day. You can’t really argue with that message.… Read More
Is it possible to find and prioritize holes in coverage through AI-based analytics on coverage data? Paul Cunningham (GM, Verification at Cadence), Jim Hogan and I continue our series on research ideas. As always, feedback welcome.
This month’s pick is Using Machine Learning Clustering To Find Large Coverage … Read More
Paul Cunningham (GM, Verification at Cadence), Jim Hogan and I launched our series on Innovation in Verification at the beginning of last year. We wanted to explore basic innovations and new directions researchers are taking for hardware and system verification. Even we were surprised to find how rich a seam we had tapped. We plan… Read More
