Description

In CI we run a couple of tests against simple system with co-sim checking. There is no test running/regression framework for these beyond a trivial script introduced by https://github.com/lowRISC/ibex/pull/1935

We should look at introducing a simple but more complete system to run these tests. The design of this system should consider how it might handle running the RISC-V conformance test suite.

Research direction

Start by reviewing the trivial script introduced by pull request 1935 and the existing CI tests for simple-system co-simulation. Define what a complete regression system should run and how it could accommodate the RISC-V conformance test suite; done means the co-simulation tests run through that system in CI.
