An output reg foo is just shorthand for output foo_wire; reg foo; assign foo_wire = foo. It's handy when you plan to register that output anyway. I don't think input reg is meaningful for module (perhaps task). input wire and output wire are the same as input and output: it's just more explicit.

WebMar 31, 2024 · We can describe our DUT using one of the three modeling styles in Verilog – Gate-level, Dataflow, or Behavioral. For example, module and_gate (c,a,b); input a,b; output c; assign c = a & b; endmodule We have described an AND gate using Dataflow modeling. It has two inputs (a,b) and an output (c). Webwire elements are simple wires (or busses of arbitrary width) in Verilog designs. The following are syntax rules when using wires: 1. wire elements are used to connect input and output ports of a module instantiation together with some other element in your design. 2. wire elements are used as inputs and outputs within an actual module declaration.
