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.

Recommendations for how to build a VLSI Analog Neural Network with Open Source Tools?
Will be doing a project using open source EDA tools (from here: https://github.com/iic-jku/iic-osic-tools) to design a VLSI analog neural network. Was wondering if there are any tutorials, resources, or other tools you guys would recommend that would provide some guidance in order to make this VLSI analog neural network?

IHP open source 130 nm BiCMOS PDK with 500 GHz fmax transistors
For this PDK there is only limited support (it is only in preview!) for klayout and ngspice - which are a FOSS and circuit simulator respectively. If you want to play with whats available, someone put up a colab script here:
https://colab.research.google.com/gist/proppy/f63686b02309e2...
The other two open PDKs, SKY130 and GF180MCU, have a more complete ecosystem the major tools being the opencircuitdesign suite, xschem and the OpenRoad project. If you're still interested, there's an easy to use docker container that has most of the tools in question already installed:

skywater pdk for IC Design
install Docker, clone iic-osic-tools github and run start_x.sh or start_vnc.sh. It's a virtual docker-container where all tools are pre-installed and configured

IHP open source 130 nm BiCMOS PDK with 500 GHz fmax transistors
This is a very fast BiCMOS process with both MOSFETs and bipolar transistors. Some digital logic can be implemented with MOSFETs but since they are 130 nm it's not very competitive with smaller cutting edge CMOS processes. Bipolar transistors are really the whole point of choosing this process and it's aimed for implementing analog and RF circuits. Bipolar transistors are extremely fast and can be used to make amplifiers operating at >200 GHz. MOSFETs can be used to implement some simple digital blocks for controlling the RF blocks.
I have made several tapeouts with this process and I have very good experiences with it. Compared to other open source PDKs that Google has open sourced previously this one is quite modern and offers very good RF performance.
It doesn't seem quite ready for design yet. Transistor models and stackup are published so schematic level simulation is possible. There is a roadmap chart in the repository (https://github.com/IHP-GmbH/IHP-Open-PDK/blob/main/ihp-sg13g...) and it seems that they are going to offer free MPW runs.
