08/25/2025: We enabled batch optimization, in run_iccad13_batch.py, 10 ILT runs in parallel and finish in 4s on RTX 6000 ADA. Morph is disabled in forward_test because it cost lots of memory.
Install Package Dependencies
pip install -r requirements.txt
Install OpenCV seperately
$sudo apt-get install python3-opencv
This is a running example on ICCAD13 benchmark images. Change the directory for your own design.
python3 run_iccad13.py
We did not include the EPE computing code in this repo, please use neuralILT or other 3rd party tools.
