# Feb 3, 2025 | ECE2700; HW 2 | Boehme, James --- # 1. ## Problem Statement: > Describe in Verilog, a full adder that accepts the following three one bit inputs: $x$, $y$, and the carry-in bit $c$; and it generates the following two one-bit outputs: the sum bit $sum$ and the carry-out bit $cout$. > **Part a)** For the first full-adder design, describe the $sum$ output using *structural* verilog, and the carry-out output $cout$ using behavioral verilog. > **Part B)** Describe the second full-adder design using *hierarchical* Verilog. Describe the half-adder module first using *behavioral Verilog*. Then instantiate two half adders in your full adder. > **Part C)** Create a Verilog testbench for the complete full-adder circuit. Make sure your testbench provides all input combinations for your full adder module. ## Given The logic expressions $$ sum = \bar{x}y\bar{c}_i + x\bar{y}\bar{c}_i +\bar{x}\bar{y}\bar{c}_i + xyc_i $$ $$ cout = xy + xc_i + yc_i $$ ## Find --- # Solution: ## A --- --- # 2. ## Problem Statement ## Given ## Find --- ---
