## Filename:    rtl/Makefile

##

## Project:     A Wishbone Controlled PWM (audio) controller

##

## Purpose:     To direct the Verilator build of the PWM example demo sources.

##              The result is C++ code (built by Verilator), that is then built

##      (herein) into an executable library.

##

## Targets:     The default target, all, builds the target test, which includes

##              the libraries necessary for Verilator testing.  It also builds

##      the pdmdemo target--building a C++ program which can be used to drive

##      this test via Verilator.
