There are three main ways to instantiate and connect modules:

  • The first two are by ordered list and by name, as in Verilog.
  • The third is by named ports.

If the names of the ports of a module match the names and types of signals in an instantiating module, the lower-level module can by hooked up by name. For example:

module lower ( output [4:0] myout; input clk;
input my_in;
input [1:0] my_in2;
... ...
//in the instantiating level.
lower my_inst (.myout, .clk, .my_in, .my_in2);
