ThreeNumbersAdder

A simple project of a circuit for adding 3 numbers in VHDL.

Circuit characteristics to implement

Implement a circuit in VHDL capable of adding 3 n-bit numbers (parametric circuit) coded in 2's complements format. The inputs and output need to be synchronized and masked using registers.

Task to perform

• Descrive the circuit using VHDL;
• Create a test bench for the logical simulation;
• Synthesize the circuit;
• Run a test bench for the post-synthesis simulation;
• Circuit implementation;
• Run a test bench for the post-implementation simulation;
• Create a documentation for the circuit;

Implementation

1. Version 1 - Ripple carry adder;
2. Version 2 - Carry save adder;
