# Simulating a Reference Design

## Overview

Details how to simulate a reference design using the provided waveform **.wcfg** file.

## Instructions

Use the following steps to simulate the reference design:

1. Start Vivado and load the project (see [Loading a Reference Design](./loading_ref_proj.md))
2. Select *Simulation->Run Simulation* from within Vivado.  

This will:
 * Start the Vivado simulator,
 * Load the waveform **.wcfg** file and
 * Display the selected signals.
3. Click on *Run All*
4. The simulation will run until completed.

Update the desired signals in the waveform and rerun as necessary.

**Note:** All reference designs come with a simulation waveform **.wcfg** file.
