Bottom-Up Methodology: In this approach, we first identify small blocks that are available to us and use them to construct a big block. Module pipeline_adder_16bit(clk,reset,a, b, cin, sum, cout) ![]() Figure 20 shows a circuit for a full adder, which has the inputs a, b, and e, and produces the. The Verilog Code of 16-bit Pipeline Adder: `timescale 1ns/1ns Writing Verilog code for Full adder using Behavioral model was explained in great detail.for more videos from scratch check this link. represent them as vectors in the Verilog code, as shown. The Verilog code of 16 bit pipeline adder is given below. The full adder also gets a carry generated from the previous adder. Every adder gets single bits from both inputs and generate a bit of carry and a bit of sum. To implement this in Verilog we used 4-bit Carry Select Adder Slice as adder slice in Verilog implementation of pipeline adder. where generateNbitAdderi is takent from the begin: statemen of the for loop and makes instances unique by adding loop iteration number. The next picture shows the entire schematic of the full adder and its corresponding truth table. The general block diagram of a Pipeline Adder is shown below. This is a sequential adder, unlike combinational adders like Ripple Carry Adder, Carry Skip Adder, Carry Look-ahead Adder etc needs a storage element and clock. A pipeline adder is a one of the fast adder using the principle of pipelining. ![]()
