Build Status codecov

This repo lets you investigate and experiment with implementing our CGRA using new generator infrastructure. Here you will find: original Genesis2 source for top level modules, functional models, and testing infrastructure. Also, you will find common generator patterns abstracted away to make designing, testing, and programming the CGRA faster.

Usage

Once garnet is installed, you can build e.g. a 2x2 CGRA simply by doing

$ python garnet.py --help
$ python garnet.py --width 4 --height 2

For installation instructions, read on.

Install and Build (also see issue #1037)

We use a docker environment to build the chip. Here's how:

Use AHA repo to boot up a docker image and container

$ git clone https://github.com/StanfordAHA/aha aha
$ cd aha; git submodule init update --recursive
$ docker build . -t aha_image           # May need sudo depending on your setup
$ docker exec -it aha_container bash    # May need sudo depending on your setup

(Inside docker now) build a 4x2 CGRA garnet.v

$ source /aha/bin/activate
$ cd /aha/garnet
$ python garnet.py --width 4 --height 2 --verilog

Verify functionality

We can verify that everything is setup properly by running the test suite using pytest.

$ cd /aha; ./garnet/.github/scripts/run_pytest.sh

(FYI last time I tried this it did not work until I first did cd /aha/garnet; git checkout master ...?)

Style guide

Please read and follow the style guide in the AHA wiki.
