Pipelined Multiply and Accumulator

This 4-stage pipelined Multiply-and-Add module is designed with ready-valid handshaking for reliable data processing.

Overview

The module performs result = (in_a * in_b) + in_c in a pipelined manner over four stages:

1. Register Inputs: Capture in_a, in_b, and in_c.
2. Multiplication: Compute in_a * in_b.
3. Addition: Add stored c value from the previous cycle.
4. Output Stage: Provide the final result.

1. Log all the data in the clock edges
2. Compare values expected vs calculated
