How to program a 4-bit adder in Verilog? - Hackatronic
Mar 24, 2024 · The 4-bit signals a and b are used to input two binary numbers into a 4-bit adder, which is an example of one. An adder can be expressed in Verilog using a continuous assignment with assign or an always block with a sensitivity list that includes all inputs because it is a combinational circuit.
