Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Compiling Code into Silicon
Pretty neat, a python tool that converts Verilog to an IC layout so that you can make your own custom SOC (assuming you have a substantial budget to pay for fab).
Since it's not clearly stated on the front page, I had to go digging to figure out what processes it supports. Looks like FreePDK45, which is "an open-source generic process design kit (PDK) (i.e., does not correspond to any real process and cannot be fabricated)" [0], ASAP7 "Warning Work in progress (not ready for use)" [1] and Skywater130 which "As of May 2020, this repository is targeting the SKY130 process node. If the SKY130 process node release is successful then in the future more advanced technology nodes may become available." [2] The floorplanner supports their ZeroSOC [3] which I guess is based on TitanSOC [4]
If this sounds negative, it's not, I just couldn't figure out what processes this was intended for without digging. ASAP7 is Arm and NCSU, and Skywater130 is Skywater and Google.
