The verilog-ams specification adds on to the verilog, (IEEE-1364-2001 or IEEE-1364-2005), versions. I will be testing cross workability with Icarus Verilog of the same spec year.
I'm not sure yet which verilog-ams version we will use to match up with netlist verilog, and not sure about needing to read the IEEE verilog specs – they're not freely available. Acellera.org free publishes Verilog-AMS Language Reference Manual, Release 2.3.1 last changed June 1, 2009.
It may be that running a quick sanity test of netlists with icarus verilog will catch blunders as well as reading IEEE-1364-2005.
