# 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 ncurses library.
#
#	Useful targets of this makefile include:
#
#	zippy_tb (default)
#		This is the test bench program / simulator that is built by
#		this directory.
#
#	test
#		Runs the simulator on a test program found in the trunk/sw/zasm
#		directory.  That program needs to be built via 'make test' in
#		that directory before this make test will work.  Changes to the
#		test itself will require a 'make test' in trunk/sw/zasm as well
#		as 'make test' in this directory.
#
#		The test itself consists of two tests.  The first, the "step"
#		test, tests whether the test works via "step"ing the CPU.
#		This would be the interface to the CPU were the CPU placed in
#		a device.
#
#		The second test is an internal test which works by just running
#		the CPU without step instructions.
#
#		In either case the test is over upon reaching either a HALT
#		or a BUSY instruction.  A HALT instruction indicates success,
#		BUSY a failure.
#
#	stest
#		Runs the test in "step" mode as described above.
#
#	itest
#		Runs the test file in interactive mode.  The CPU will not 
#		execute any instructions without user interaction.  This is
#		useful for actually debugging the test.  The other two modes
#		are useful for quickly determining that the CPU does (or
#		doesn't) work.
#
#	dhrystone
#		Runs a hand-optimized version of the dhrystone benchmark.  
#		Using the instructions at the top of the dhrystone assembly
#		file, you should be able to convert the result to DMIPS or even
#		DMIPS/MHz.
#
#	div_tb
#		A raw test bench to test the divide unit separate from the
#		rest of the CPU.  This test will fail with a failed assert()
#		if unsuccessful, or complete with no error (but lots of
#		debugging output) if successful.  To actually run this test,
#		you'll need to run ./div_tb (no arguments necessary).
#
#	pdump
#		zippy_tb can be configured to produce a profile output that is
#		very useful when debugging the Dhrystone benchmark.  (It is
#		so configured by default.)  This file will be name pfile.bin.
#		pdump is a very simple program designed to read this file and
#		produce some (very raw) information from it.  To use this,
#		type pdump and the name of the executable file, such as 
#		../asm/zipdhry.z, and examine how many times each instruction
#		was executed, and how many stalls took place between each
#		instruction and the next.
#
#	clean
#		Removes all products of compilation--specifically zippy_tb,
#		pdump and div_tb.
