Description
It would be worth writing properties for the top-level Ibex interfaces and then trying them out on Yosys. @rswarbrick has been working on properties around the icache using Yosys so has already done some of the work here.
From prior experience simple properties around protocol checking can find a surprising number of bugs (e.g. properties on correct behaviour on the data interface could unearth things that are broken with the writeback stage).

Research direction
Start by reviewing the top-level Ibex interfaces and the existing icache properties that have been tried with Yosys. Define protocol properties for the interfaces and run them through Yosys; done means the properties cover the intended correct behavior and produce useful verification results.
