Hi Billy,
The code below works for me. You will get a warning from the UVM, but that is a symptom of the factory and parameterized classes - you can ignore it.
In the snippet:
case (i)
0: begin
$display("Making 7");
//c = p7::type_id::create("p7", this);
c = parameterized_class#(7)::type_id::create("p7", this);
end
1: begin
$display("Making 1000");
//c = p1000::type_id::create("p1000", this);
c = parameterized_class#(1000)::type_id::create("p1000", this);
end
endcase
there are TWO possible solutions. One is the code as you wrote it. The other code is a non-parameterized wrapper around the parameterization (the commented out lines creating a 'c'). The wrappers are the class definitions 'p7' and 'p1000'. Personally, I don't prefer the wrapper. I prefer the code the way you wrote it.
Best regards,
