OpenDP: Open Source Detailed Placement Engine

If you want to use this as part of the OpenROAD project you should build it and use it from inside the integrated openroad app. The standalone version is available as legacy code.

Visualized detailed placement result using aes_cipher_top design with innovus initial placement; OpenDP_sample.jpg
