"WebBasically your code ignores the input A because you are assigning it to a non-existent variable. Secondly, your second code uses a bit shift ( >> ), not an arithmetic shift ( >>>) so will not perform sign extension (see below). The result your second module calculates is exactly the correct result for the hardware you have described. " - Bit shifting in verilog
