#
# 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 and ncurses libraries.
#
#       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).
#
#       mpy_tb
#               A raw test bench to test the multiply instructions within the
#               cpuops (ALU) unit separate from the rest of the CPU.  For more
#               details, look at the usage statement wtihin mpy_tb.
#
#       pfcache_tb
#
#       zipmmu_tb
#               Like div_tb, this is another raw component test bench.  In this
#               case, zipmmu_tb tests whether or not the MMU works when
#               separated from the rest of the CPU.
#
#       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.
