3
# Filename:     Makefile
4
#
5
# Project:      Zip CPU -- a small, lightweight, RISC CPU soft core
6
#
7
# Purpose:      This makefile builds the final verilator simulation of the
8
#               zipsystem.  Specifically, it builds the final C++ portion
9
#       of the simulator, and thus the final simulator executable.
10
#
11
#       This simulator depends upon the libelf and ncurses libraries.
12
#
13
#       Useful targets of this makefile include:
14
#
15
#       zippy_tb (default)
16
#               This is the test bench program / simulator that is built by
17
#               this directory.
18
#
19
#       test
20
#               Runs the simulator on a test program found in the trunk/sw/zasm
21
#               directory.  That program needs to be built via 'make test' in
22
#               that directory before this make test will work.  Changes to the
23
#               test itself will require a 'make test' in trunk/sw/zasm as well
24
#               as 'make test' in this directory.
25
#
26
#               The test itself consists of two tests.  The first, the "step"
27
#               test, tests whether the test works via "step"ing the CPU.
28
#               This would be the interface to the CPU were the CPU placed in
29
#               a device.
30
#
31
#               The second test is an internal test which works by just running
32
#               the CPU without step instructions.
33
#
34
#               In either case the test is over upon reaching either a HALT
35
#               or a BUSY instruction.  A HALT instruction indicates success,
36
#               BUSY a failure.
37
#
38
#       stest
39
#               Runs the test in "step" mode as described above.
40
#
41
#       itest
42
#               Runs the test file in interactive mode.  The CPU will not
43
#               execute any instructions without user interaction.  This is
44
#               useful for actually debugging the test.  The other two modes
45
#               are useful for quickly determining that the CPU does (or
46
#               doesn't) work.
47
#
48
#       dhrystone
49
#               Runs a hand-optimized version of the dhrystone benchmark.
50
#               Using the instructions at the top of the dhrystone assembly
51
#               file, you should be able to convert the result to DMIPS or even
52
#               DMIPS/MHz.
53
#
54
#       div_tb
55
#               A raw test bench to test the divide unit separate from the
56
#               rest of the CPU.  This test will fail with a failed assert()
57
#               if unsuccessful, or complete with no error (but lots of
58
#               debugging output) if successful.  To actually run this test,
59
#               you'll need to run ./div_tb (no arguments necessary).
60
#
61
#       mpy_tb
62
#               A raw test bench to test the multiply instructions within the
63
#               cpuops (ALU) unit separate from the rest of the CPU.  For more
64
#               details, look at the usage statement wtihin mpy_tb.
65
#
66
#       pfcache_tb
67
#
68
#       zipmmu_tb
69
#               Like div_tb, this is another raw component test bench.  In this
70
#               case, zipmmu_tb tests whether or not the MMU works when
71
#               separated from the rest of the CPU.
72
#
73
#       pdump
74
#               zippy_tb can be configured to produce a profile output that is
75
#               very useful when debugging the Dhrystone benchmark.  (It is
76
#               so configured by default.)  This file will be name pfile.bin.
77
#               pdump is a very simple program designed to read this file and
78
#               produce some (very raw) information from it.  To use this,
79
#               type pdump and the name of the executable file, such as
80
#               ../asm/zipdhry.z, and examine how many times each instruction
81
#               was executed, and how many stalls took place between each
82
#               instruction and the next.
83
#
84
#       clean
85
#               Removes all products of compilation--specifically zippy_tb,
86
#               pdump and div_tb.
