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.

Building a HDL (Kind of)
I've felt frustrated about SV and front end development for hardware and have been developing ROHD (https://github.com/intel/rohd) and it's been a worthwhile endeavor

Discussion Thread
Dart is a general purpose language, there even is a hardware development framework by Intel which is made in Dart

[CocoTB for beginners]: FPGA/ASIC Testbenches in Python + Automated Testing in GitHub​
I was hoping to decouple the designs from any particular vendor as much as I could so I would interface with the core (dut) with a Cocotb AXI Lite master to get/set registers. Then if I were using something like an AXI Stream to send/receive audio or video data there was a Cocotb python driver to process the data in the test bench. As an example, in part 5 the graphics core generated a 16x4 color bar image over AXI video stream that was captured by a Cocotb AXI Stream sink and then 'displayed' as hex values in one of the test.

Simulating AXI Accessing to DDR
This is where you can use a BFM (bus functional model). Basically, you can connect your design to a simulation model of the RAM. I wrote some cocotb extensions for doing stuff like this in cocotb, you can give that a try, assuming your code works with a simulator that's compatible with cocotb: https://github.com/alexforencich/cocotbext-axi

Cocotb
The cocotb bus repo has many of the useful drivers and monitors. https://github.com/cocotb/cocotb-bus/tree/master/src/cocotb_bus. There is also https://github.com/alexforencich/cocotbext-axi for some relevant AXI examples that you can also just use.
