We are pleased to let you know that our recent paper titled "Design and Optimization of Low-Dropout Voltage Regulator Using Relational Graph Neural Network and Reinforcement Learning in Open-Source SKY130 Process" has been accepted to the 2023 IEEE/ACM International Conference on Computer-Aided Design (ICCAD): https://iccad.com/accepted-papers. This is the first paper (as of my knowledge) that demonstrates the feasibility of applying reinforcement learning to optimize analog circuits using open-source PDK, and therefore it is completely open-sourced! We will post the accepted paper soon, but you are all welcome to go ahead and reuse the code I have in my repository here: https://github.com/ChrisZonghaoLi/sky130_ldo_rl/tree/main Thanks for your interest!

Congrats, that is awesome!
