Module 2.1 Gate-Level/Structural Modeling UNIT 2: Modeling in Verilog. - ppt download: PORTS A module definition contains an optional list of ports. (If the module does not exchange any signals with the environment, there are no ports in the list). Consider a 4-bit full adder that is instantiated inside a top-level module Top. The module fulladd4 takes input on ports a, b, and c_in and produces an output on ports sum and c_out. I/O Ports for Top and Full Adder module fulladd4(sum, c_out, a, b, c_in); //module with a list of ports module Top; / / No list of ports, top-level module in simulation
