$lsi_dumpports(test.u0.u1,"dump.out2");

end

top u0 (a);

endmodule

module top(a);

input a;

middle u1 (a);

endmodule

module middle(a);

input a;

wire b;

buf(b,a);

endmodule

By using the method in this example, the port a of instance u1 is

driven from the outside, and when $lsi_dumpports checks for the

drivers it reports a code of D as desired.
