WebBitwise operators ¶ Four bitwise operator are available in verilog i.e. ‘&’ (and), ‘ ’ (or), ‘ ^ ‘ (xor) and ‘~’ (not). Further, we can combine these operators to define new operators e.g. ‘~&’ or ‘&~’ can be used as ‘nand’ operations etc. 3.8.2. Relational operators ¶

WebSep 21, 2024 · Given a dividend ‘a’ and a divisor ‘b’, the restoring division algorithm calculates the quotient ‘q’ and the remainder ‘r’ such that a = b x q + r and r < b, by subtracting b from the partial remainder (initially the MSB of a).
