Hi,
with latest master, I get further. Now the stopping point are the non-ANSI port declarations:
module ADD2( CO, ICO, S, A, B, C, D );
input A, B, C, D;
output CO, ICO, S;
endmodule;
Produces something like:
** Error: syntax error, unexpected ',', expecting ';'
> /projects/pdks/<fancy_pdk_under_nda>/<standard_cell_type>/0v2/behav_model/<again_fancy_pdk>.v:5
|
5 | input A, B, C, D;

Hi @nickg , thanks for the fixes.
With latest master I now get up parsing the underlying "func" instance that is before the specify block:
[oille@runner4 build]$ nvc -a /projects/pdks/<pdk_under_nda>/<standard_cell_library>/0v2/behav_model/pdk_under_nda.v
** Error: syntax error, unexpected '.', expecting identifier
> /projects/pdks/<pdk_under_nda>/<standard_cell_library>/0v2/behav_model/pdk_under_nda.v:14

14 | SIMPLE_GATE_func SIMPLE_GATE_inst(.CO(CO),.ICO(ICO),.S(S),.A(A),.B(B),.C(C),.D(D));

Maybe better than posting here from proprietary PDK is referencing something public.
I tried to compile standard cell models of IHP 130 nm PDK: IHP 130 std cells model
Currently it fails with:
[oille@runner4 build]$ nvc -a ../sg13g2_stdcell.v
** Error: syntax error, unexpected '(', expecting identifier
> ../sg13g2_stdcell.v:25

25 | and (int_fwire_0, A1, A2);

Looking at that PDK, I think following features are still missing to at least parse it:
Hi,
after seeing
https://github.com/nickg/nvc/issues/808
I gave it a shot at compiling Verilog standard cell libraries I have available for a PDK that we use. I see couple of macros unsupported:Tried to put together MVP example of the cell from PDK:
Note that this has several other issues (non-ANSI port declaration, specify blocks), but its the most rudimentary cell definition I could create. Feel free to close/do whatever with the issue if it is too soon and the verilog implementation is not yet there.
