Re: gEDA-user: Edif net format

["CN" <mis4@xxxxxxxxxxx>]

Steve,


Here ivl appears to do that. I ran the included sqrt-virtex.v with -tfpga -parch=virtex, and here is part of the output (see the first and last lines below):


(net N913 (joined (portRef O (instanceRef U30)) (portRef I1 (instanceRef U48))))

(net N914 (joined (portRef O (instanceRef U32)) (portRef I0 (instanceRef U48))))

(net N915 (joined (portRef O (instanceRef U29)) (portRef I1 (instanceRef U47))))

(net N916 (joined (portRef O (instanceRef U31)) (portRef I0 (instanceRef U47))))

(net N917 (joined (portRef O (instanceRef U28)) (portRef I1 (instanceRef U46))))

(net N918 (joined (portRef O (instanceRef U30)) (portRef I0 (instanceRef U46))))


Let me know if you need any additional info.


Cordially,

CN

That's not allowed by EDIF. (At least not EDIT 2 0 0, which is what I

have the documentation for.) Icarus Verilog doesn't do that, does it?
