## Filename: sw/Makefile
##
## Project: A multiply core generator
##
## Purpose: This is the main Makefile for the multiply core generator.
## It builds the software to build a multiply core, and possibly
## a couple of test cores.
##
## Targets include:
## all Builds the multiply core only
##
## bldmpy Builds the multiply core
##
## test Builds a variety of multiply cores in the rtl/
## directory
