Verilog supports the use of a bit-wise operator. You can’t synthesize it with regular Verilog unless it’s by a power of two, which uses a right shift. A right shift truncates the result, so we lose the fractional part: However, with fractional numbers, we can do accurate division by a constant using multiplication. For example, to divide by 2 we multiple by 0.5: Back in Q4.4: 0011.1100. Z = - Z; end. Simulation result verified the correct operation of the multiplier which 14 multiplies by 11 getting 154 at the output of the multiplier. We can solve this problem with the shift operator.
