A Comparison of Formal and Simulation for a Simple, Yet Non-Trivial Design - Part 1

by Tudor Timi on Verification Gentleman
teaser image I've talked a lot about constrained random verification on the blog, but now it's time to branch out to formal verification. As a fun first post on the topic, I thought we could do a comparative study. We can take a design and write two verification environments for it, one using formal verification and the other using simulation, based on UVM. Once we're done, it should be very interesting to be able to look at them side-by-side and to do an analysis.I thought long and hard about which one ...

How we used differential testing to rapidly find and fix missed optimisation opportunities in LLVM's RISC-V backend

by Luís Marques on lowRISC: Collaborative open silicon engineering
At this October 2020 LLVM Developers’ Meeting I presented a poster about how, with a surprisingly simple tool, we were able to rapidly identify, isolate, and fix a range of missed optimisation opportunities in LLVM’s RISC-V backend. The tool works by generating random C programs, compiling each program with both Clang and GCC (targeting RISC-V) and comparing the assembly generated by both compilers. If it estimates that Clang/LLVM generated worse code than GCC then it saves that case ...
