Array of generalized interfaces

There are 2 problems I’d like to solve.

  1. A parametrizable array of interfaces.

Let’s say I define an array of interfaces and pass them to a module instance:

module top;

base_interface [7:0] my_ifs;

super_dut #(NUM_IFS=8) dut (
.ifs (actual_ifs[NUM_IFS-1:0])
);

endmodule

That’s legal SV, right?

  1. “derived” interfaces

Suppose I have 10 different interfaces. In principle I’d like to have a “base interface” from which each is derived. Then I could use the code in #1 and get a “parametrizable generalized interface”. But SV doesn’t support the notion of “child” interfaces the way it supports derived classes.

Is there a way to implement such a concept?

Couldn’t you implement an interface that’s the union of all 10 interfaces, and make that the “base” interface? That gets a bit messy, but it seems like it would work.

Any way to do it more cleanly?

Thanks!
