Yes. But I focus on *functional* simulation, not on *structural*. My
model for my cpu is a pure software thing, not concerning on signals,
gates or event schedule. The goal is to verify my cpu on the
architecture level, to debug my cpu code in a fast and friendly
environment and to generate test cases for verilog/hardware simulation.

No. Almost every eda tools support Tcl which is easer than ruby and
good enough for these tasks.

Maybe. Ruby, Tcl, event VB script if I do my design in ms excel.

I don't have an optimistic view of it :(
