I should point out here that these simulator specific models
may in fact be loadable VPI or PLI modules with a wrapper. This
is for example how the Denali models work. If there is interest
in getting these working with Icarus Verilog, the place to start
is with the vendor. Prod them specifically about Icarus Verilog.
I was able to for example get out of Denali that they use PLI
to interact with Verilog simulators and *would* be interested
in working with me on getting them working with Icarus Verilog,
but wanted to see some pull from customers first.
So the moral is that it may make some sense to ask the model
vendor directly. They just *might* be open to cooperation,
especially if you are a customer spending money on them.
