I don't see anywhere in the BNF how you can specify the drive strength for
a plain module instantiation.
Both XL and VCS accept this, yet it isn't documented anywhere.
What should be done with this? Erratta?

<p>module adam( Y, A, B);
parameter tr = 1;
parameter tf = 1;
parameter m = 1;
input A, B;
output Y;
<p>initial begin
$display("The parameters are %0d %0d %0d.", tr,tf, m);
end
// Here are valid drive strength parameters!!
nor (strong0, strong1) #( tr, tf) G1(Y, A, B);
endmodule
