# Filename:     Makefile

#

# Project:      Zip CPU -- a small, lightweight, RISC CPU soft core

#

# Purpose:      This makefile builds the final verilator simulation of the

#               zipsystem.  Specifically, it builds the final C++ portion

#       of the simulator, and thus the final simulator executable.

#

#       This simulator depends upon the libelf library.

#

# Creator:      Dan Gisselquist, Ph.D.
