How to use Find Scope in Synopsys Verdi

Question

The "Find Scope..." option in Synopsys Verdi doesn't seem to be able to find anything other than top level modules. I have the Scope Type set to Module and I have tried a bunch of different variations:

1) the module name with the * wildcard before and/or after: this will find top level modules no problem, but not anything lower.
2) The path to the module separated by .
3) The path to the module separated by /
4) Variations 2 & 3 with the * wildcard.

There must be something simple I am missing, but what is it?

Answer 1

By default, Verdi treats modules compiled using -y as "library" modules, and they are not visible in the nTrace GUI.

The solution is to use the verdi -ssy command line option to gain visibility into the library modules.

Consider this scenario. I have 3 Verilog files:

1. tb.v
2. lib/foo.v
3. lib/bar.v

If I launch Verdi with the following command, it will compile cleanly, but the submodules (foo and bar) will not be visible in the GUI. Only the top-level modules are visible:

verdi tb.v -y lib +libext+.v

To gain visibility, add the -ssy option:

verdi tb.v -y lib +libext+.v -ssy

I can see all modules in the hierarchy.

tb.v:

module tb;
    foo i0 ();
    foo i1 ();
    foo i2 ();
endmodule

module tb2;
endmodule

foo.v:

module foo;
   bar b0 ();
   bar b1 ();
endmodule

bar.v:

module bar;
endmodule
