Understanding the 4-bit Ripple Carry Adder: Verilog Design and Testbench Explained
In digital electronics and VLSI design, adders are fundamental building blocks used to perform arithmetic operations. Among various types of adders, the 4-bit Ripple Carry Adder (RCA) is one of the simplest and most commonly studied designs. It is widely used to add two 4-bit binary numbers and produce a 4-bit sum along with a carry-out. This…
