WitrynaThe Verilog bitwise operators are used to perform a bit-by-bit operation on two inputs. They produce a single output. They take each bit individually and perform a boolean algebra operation with the other input. The table of bit wise operators is shown below: Refer to this page for a refresher on what each of these truth tables looks like.
