SkyPlace - A VLSI global placer with GPU-acceleration

Please READ
Thanks for your attention on this repo!
Alpha version is just uploaded for those who are interested in this project.
Though SkyPlace was originally coded to run bookshelf format benchmarks,
The whole source code is re-implemented to support lef/def format as well.
This made huge amount of bugs and still many of them are remaining (this is why open-sourcing has been delayed).
Please do not expect this code will run safely.
Especially, bookshelf flow is currently not available.
(you can run by read_bookshelf command but the results are not valid)
We will upload more reliable version as soon as possible. (09/15/24)
