Although Yosys calls it "formal verification", industry calls it "static functional verification", and I (coming from software) would call it "model checking with a SAT solver" or "property testing". Kami would be true "formal verification".

Privately, I expressed this concern for confusion with Yosys developers and they agree, so I think nMigen should be more careful in its use of "formal" also.

This affects 0.1 as we have nmigen.formal which needs to be renamed.

Renamed to nmigen.asserts, because that module contains Assert, Assume and related items. Essentially, I am calling it "nMigen Assertions", similar to "SystemVerilog Assertions" aka SVA.
