Repo for AVR instruction set test and implementation in VHDL
This project targets the AT90S4414 device. In order to run assembly simulator for this device, you need to install AVR Studio 4? (verifying this now). Newer versions deprecate support.
Once you have GHDL and osvvm installed, run commands from the Makefile:
make import
Test memory access unit (mau):
make mau_tests
Test general purpose registers:
make avr_reg_tests
For simulation, this code uses GHDL. Install GHDL from pre-built binaries (available online), or, alternatively, build from source.
apt update
apt install -y gnat
git clone git@github.com:ghdl/ghdl
cd ghdl
git checkout v0.37.0
./configure --prefix=/usr/local
make
Then, install the built code. I prefer to use checkinstall to wrap packages, but you can also just directly do make install.
You will also want to install gtkwave to visualize the tests:
apt install gtkwave
After doing all this, go through Quick Start Guide to learn basics: https://ghdl.readthedocs.io/en/stable/using/QuickStartGuide.html
See this link: https://ghdl.readthedocs.io/en/stable/building/PrecompileVendorPrimitives.html?highlight=osvvm
Summary of instructions:
- Clone osvvm repo to a folder on your computer
- modify config.sh file of ghdl to point to the ossvm cloned repo for osvvm source
- run compile-osvvm script in ghdl. This script will compile osvvm and put an osvvm folder in your current folder. Run this in root
See the above link for original source docs that will (hopefully) be kept up to date.
