CGRA-Flow is an integrated framework for CGRA compilation, exploration, synthesis, and development.

User Interface Snapshot/Demo

A demo at repl.it (https://repl.it/@ChengTan/cgra-flow) shows some features of CGRA-Flow (the verilog generation and evaluation are not available due to repl.it's limited support of python environment). To explore all the features, please setup CGRA-Flow locally or leverage the docker image.

Docker

The docker image is available here.

As CGRA-Flow requires GUI, a script is provided for setting up the display:

 docker pull cgra/cgra-flow:20241028

 # For Mac users:
 sh ./run_mac_docker.sh

 # Windows Docker customtkinter style UI (Please setup GUI (X-11) first)
 # In WSL, execute below script, it will enter container and config x11 DISPLAY automatically
 sh ./run_linux_docker.sh

 # Don't forget to activate the python virtual environment once you are in the container:
 source /WORK_REPO/venv/bin/activate

Otherwise, if you don't need the GUI, development can be performed in the container with the environment well set up:

 docker pull cgra/cgra-flow:20241028
 docker run -it cgra/cgra-flow:20241028
 source /WORK_REPO/venv/bin/activate

Execution

 # Startup theme mode selector UI
 python launch.py

Installation

CGRA-Flow requires Python3.7.

Refer to the build scripts or look into specific repo for the manual installation if you don't want to use docker.
