OVPsim beats QEMU in fidelity in CPU simulation - its determinism and speed were pretty impressive. OVPsim configurability is a big advantage as well. We were able to configure low-level CPU features, thanks to comprehensive documentation. I was also enthusiastic about the machine description file. It was easy to connect a missing interrupt signal we needed.

Flexibility within a framework of compatibility is the essential foundation of the RISC-V ISA.
The RISC-V P extension defines a rich set of integer SIMD/DSP instructions operating on existing integer registers to support complex data processing within the constraints of real-time applications. However, the hardware specification is just the start - adoption and success depend on the software ecosystem, which is supported with the reference models and test suites from Imperas.
