## 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:
##
##      zipsys_tb (default)
##              This is the test bench program / simulator that is built by
##              this directory.  This is based upon the ZipSystem.
##
##      zipbones_tb (default)
##              This is the test bench program / simulator that is built by
##              this directory--save that this ones uses the ZipBones.
##
##      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
##              zipsys_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 zipsys_tb,
##              pdump and div_tb.
