Description

The guys at Antmicro have been working on their Surelog+UHDM+Yosys flow and it seems that it can now build Ibex with vanilla Yosys plus their stuff as a plugin.

It would be neat if we could try running this in CI. We'd get early warning if we made a change that broke their frontend (possibly a sign of a genuine Verilog error) and we'd also get instant kGE estimates.

We'll need to decide which version of the software to track and how to "install" it. Maybe the right approach would be for Antmicro to generate a docker image containing the tool, so we could consume that?

We'll also need to figure out how to run stuff. A GitHub action? Some sort of Azure integration?

Research direction

No files or tests are named. Start by reviewing the existing CI setup and the Ibex synthesis flow, then resolve the tool version, installation method, and CI execution environment with Antmicro. Done means CI runs the Surelog/UHDM/Yosys flow and provides build-failure warnings and kGE estimates.
