I'm specifically interested in this, yes. That would at the worst
give me an opportunity to get the parsing/elaboration of Verilog-A
worked out by using a code generator that generates gnucap
plugins. That would be good for you (gnucap gets a plug-in devel
tool) and for Icarus Verilog. So even if the Icarus Verilog run
time never gets analog support, there is use for the analog
syntax.

It might also be interesting for the vvp run time to farm off
handling of analog kernels to gnucap, if vvp can get back from
gnucap information about analog events that it needs to feed the
vvp scheduler. I haven't settled on whether that would be better,
or if it would be better to keep the analog kernel processing
in threads of the vvp process itself. Lots of thought yet to be
done here.

Now this is getting pretty fancy.
