#
#
 
#       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.
