PCB Dataset for placement and routing

Hello!
I’m looking for a dataset that can be used to train a model for PCB components placement and routing tasks, and if someone has some knowledge on how to go about this.

This dataset would help me have a base policy that I can use later to finetune with RL.

PS: I know it’s an NP-hard problem by itself, and probably a dataset is not the way to go, but I still would like to find such a collection. I’ve already searched and didn’t find.
