This project implements a 4-bit Parallel Adder/Subtractor in Verilog using a Ripple Carry Adder (RCA) and logic gates like XOR, AND, and NOT. The design can perform both addition and subtraction based ...

This circuit implements a 4-bit magnitude comparator using basic logic gates in Wokwi. Two 4-bit values (A and B) are entered via the DIP switch (sw1). The logic compares whether A > B and outputs the ...
