Concatenation with an equality test result does not behave as expected

[sgherbst]

Noticed that a module doesn't get instantiated in a conditional statement in a generate block when the condition uses a parameter calculated by concatenating with an equality test result. It looks like this also happens if a relational operator is used.

A.v

module A;
    parameter N = {1'b0, (1 == 1)};

    generate
        if (N == 2'b01) begin
            B b();
        end
    endgenerate
endmodule

B.v

module B;
endmodule

Command:

surelog -nocache -parse -nouhdm +libext+.v -y . A.v

Output in slpp_all/file_elab.lst

/path/to/slpp_all/lib/work/A.v

Excepted result: seeing both A.v and B.v in file_elab.lst

Surelog 1.82 macOS 12.6.6

Works like a charm, can't reproduce. Rebuild Surelog from scratch.

Thanks! Can confirm that this issue is resolved after building from the latest commit (97e3ae6). If you have a chance, would you mind creating a 1.83 release?

I take care of creating a new release 1.83 of UHDM and Surelog if you don't mind @alaindargelas ?

Sure @hzeller

Alright, tagged UHDM and Surelog with 1.83
