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.

Verilog functions and wires
I see what you mean by some online examples adding begin...end in functions. They are not actually required, and many people choose to leave it out (sv2v, lowRISC, BSG). I don't believe there is a benefit to adding them, and it just creates more opportunities for bugs that compilers/linters cannot check.

[D][P] Represent Analog Circuits as Graphs
I would suggest Verilog-to-routing as the best open source tool ive used that deals with abstract circuit representations on an FPGA or similar architecture. but tools like Align and Magical both accept circuit inputs as netlists and have to represent them internally for generating layout so might be easier to understand their approach depending on your familiarity with analog circuits. One more option is to look up OpenLane flow, its more an amalgamation of lots of tools but definitely also represents circuits as a graph for manipulation later on.

Kickstarting IC design
And, there is a project called 'The OpenROAD Project' which has created an open-source framework for digital back-end design/physical design. https://github.com/The-OpenROAD-Project/OpenLane

How are modern processors and their architecture designed?
For "how the architecture is brought to silicon": Look at OpenLane. It's a complete Verilog to GDS flow, all open source and already used for some tape-outs. https://github.com/The-OpenROAD-Project/OpenLane

Project Ideas for Uni
Maybe you can do something that can also go to an ASIC. Take a look at openlane flow, you don't need to do the backend since it is mostly script based and you can even send it to next Skywater submission. The major problem is that you currently don't have sram access so you need to create rams from logic if you need to.

I am not sure if you can do padding with this but dropping this down in case you haven't heard it: https://github.com/The-OpenROAD-Project/OpenLane

Resources for a physical design engineer
Specifically openlane (https://github.com/The-OpenROAD-Project/OpenLane is a great way to start, although it's very painful trying to do complex designs. However, they're pretty helpful answering questions on Gitter
