I am attempting to submit a bug report for the following: Internal Error: Sub-system: VRFX, File: /quartus/synth/vrfx/verific/verilog/veriid_elab.cpp, Line: 3543

Software

Version 18.0.0 Build 614 04/24/2018 SJ Lite Edition

 

Suspected Manifestation of the Error

I am attempting to pass an interface to a module. This error appears when I simply pass the interface rather than a modport.

interface ifc(); ... modport mp(....); endinterface: ifc   module test_i(ifc a); ... endmodule: test_i   module test_o(ifc.mp a); ... endmodule: test_o   module top(); ifc A0(); test_i T0(.a(A0)); //Crashes test_m T1(.a(A0.mp)); //Survives -- But Requires Many Changes ... endmodule: top

Apologies for my slow reply @KennyT_Intel​ ,

 

I worked around this a while ago but I will attempt to return to the revision and extract a simplified example which can be made public once I get a chance.
