Code samples: |
============= |
|
This directory contains a few test applications that can be simulated and run |
on real hardware, except for the opcode test which can only be simulated). See |
on real hardware (except for the opcode test which can only be simulated). See |
the readme file and the makefile for each program. |
|
The makefiles have been tested with the CodeSourcery toolchain for windows (that |
can be downloaded from www.codesourcery.com) and with the Buildroot toolchain |
can be downloaded from www.codesourcery.com). They should work with other |
toolchains and have been occasionally tested with the Buildroot toolchain |
for GNU/Linux. |
|
Most makefiles have two targets, to create a simulation test bench and a |
synthesizable demo. |
|
Target '*_sim' (e.g. 'hello_sim') will build the simulation test bench as vhdl |
file '/vhdl/tb/mips_tb1.vhdl'. This is the default test bench expected by the |
simulation script '/sim/mips_tb1.do'. |
Target 'sim' will build the simulation test bench as vhdl file |
'/vhdl/tb/mips_tb2.vhdl'. This is the default test bench expected by the |
simulation script '/sim/mips_tb2.do'. |
|
Target '*_demo' will build a synthesizable demo as '/vhdl/demo/mips_mpu.vhdl'. |
Target 'demo' will build a synthesizable demo as '/vhdl/demo/mips_mpu.vhdl'. |
|
The build process will produce two binary files '*.code' and '*.data' that can |
be run on the software simulator: |
The build process will produce a number of binary files that can be run on the |
software simulator. A DOS BATCH file has been provided for each sample that |
runs the simulator with the proper parameters (swsim.bat). |
|
slite hello.code hello.data |
|
Plus a listing file (*.lst) handy for debugging. |
|
Support code library: |
===================== |
|
The python script 'bin2hdl.py' is used to insert binary data on vhdl templates. |
Many of the code samples use support code from an ad-hoc library included with |
the project (src/common/libsoc). Before making any of the samples you should |
make the library ('make' with no target). That will build file |
'src/common/libsoc/libsoc.a'. |
|
|
|
Building VHDL code from templates: |
================================== |
|
The python script 'bin2hdl.py' is used by all the samples to insert binary data |
on vhdl templates. |
Assuming you have Python 2.5 or later in your machine, call the script with |
|
python bin2hdl.py --help |
