# Simulation script for testing stat_mod.vhd

# Note: this file assumes you have held to the interface proposed 
# in Homework 2.  

# This do file also assumes your resolution is set at 1 ns

# For small components, a simple force .do file allows you to easily 
# simulate your design.  As your designs become more complex, a testbench
# is usually created such that you do not have to manually force the input
# signals to be as you wish.
