Re: [Iverilog-devel] Fwd: Support for experimental logic states

[Cary R. <cy...@ya...>]

 Hi Daniel,
Could you describe what you are trying to do in a bit more detail? For example what is X polarity and how do you want to use it?

Conceptually adding new logical states is possible and could likely be done in a manner that would be mostly transparent to existing functionality.

Also if you are interested in efficient logic functionality, way too long ago I started experimenting with creating a general purpose library that supports all the Verilog operators for either 2 or 4 state logic. Unfortunately I have had no time to work on it for years though it has a bunch of functionality completed and I have many more ideas floating around in my brain regarding how it could be added to Icarus.

Knowing what you are trying to do in more detail should allow us to understand and better describe how Icarus could be used to satisfy your goals.

The VHDL target is fairly limited in what it supports, and hasn't been 
maintained for many years, so I wouldn't recommend it.
