WebJan 12, 2024 · Verilog Code for Half Subtractor. To write the Verilog code, first, we need to analyze the logic diagram of half- subtractor. Especially when we are considering structural modeling. We can see three logic gates being used in the circuit. An XOR gate, an AND gate, and a NOT gate. So we’ll structurize these particular modules. WebJul 1, 2024 · There are four digits in the inputs, so we need four steps. For each step, we shift the left-most digit of the dividend A into ACC, then compare it with the divisor B. If ACC is greater or equal to B, then we subtract B from ACC and add 1 to the quotient QUO. This is easiest to see by working through the example:
