# Purpose: This makefile builds the final verilator simulation of the
|
# Purpose: To direct and simplify the build of a variety of simple test
|
# zipsystem. Specifically, it builds the final C++ portion
|
# programs which will use one (or both) of the ZipCPU simulators.
|
# of the simulator, and thus the final simulator executable.
|
#
|
#
|
# Targets include:
|
# This simulator depends upon the ncurses library.
|
#
|
#
|
# helloworld
|
# 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.
|
|
#
|
|
# 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.
