How to get a module to display it's own instance name?

[Mike Sendrove]

Hi:
Is it possible to get a testbench model (in this case, a RAM, but that's
irrelevant) to report its own instance name using a $display or similar
construct? I assume there's some sort of parameter built in to the language,
but I can;t for the life of me find it.
I am currently using VCS and nc/xl simulators.
Many thanks,
Mike

$display("%m")

A %m in a $display format will print the full hierarchical name of the
scope in which it appears (generally a module instance). The %m does
not use up one of the arguments to the $display, since it is not printing
one of them.

%m will do it:

module a ();
b b ();
endmodule

module b ();
initial
$display("My instance name is %m"); // My instance name is a.b
endmodule
