WebAssume that you have two 8-bit 2's complement numbers, a [7:0] and b [7:0]. These numbers are added to produce s [7:0]. Compute whether a (signed) overflow has occurred. Now my answer to the asked value of overflow was. assign overflow = ~ (s [7]&a [7]&b [7]); While the correct answer shown was. WebThe 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 …
