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.

Logik: Open-source FPGA toolchain by Zero ASIC
Theres the open source Digital (https://github.com/hneemann/Digital) which can run simulations but then export Verilog. If you have an ICE40 based GPU then in theory you can then use open source tools (like apio) to get that onto your FPGA. I've seen some impressive fpga tasks being generated by that.
I'm early in my learning of FPGA and have done nandgame and some other non-HDL circuit learnings. I have gone back and forth if I want to design my project via HDL or via something like Digital. There's not an easy pro/con either way.

How can I implement a simple asynchronous DRAM controller? (2018)
Used the recommended JRT https://adoptium.net/
Wandered through the https://github.com/hneemann/Digital site and saw past issues with JRT but no obvious solution.
I have a couple hundred GALs of same or similar model number of new old stock

Check if https://github.com/hneemann/Digital and/or Logisim are for you.

4 bit multiplier, logic visualized
someone posted a logic gate graph some days ago which sent me through a loop of remaking a 4bit multiplier i designed in Digital Logic, in desmos. unfortunately everything is pretty much explicitly defined and put together as to maintain only the appearance of this exact circuit, so theres no ui for placing components drawing wires and building your own circuits. yet ;]

What is preferable as self-thought development
This is my favorite book and I read it while trying to create the circuits myself before learning the chapter using digital - it's very enlightening and I recommend you do the same

GHDL on mac m1
I downloaded https://github.com/ghdl/ghdl/releases/download/v3.0.0/ghdl-macos-11-mcode.tgz and extracted it to home directory ~.

If someone is good at programming languages like C, will they be good at description languages like VHDL?
Also, VHDL has its roots in Ada, not Pascal. (In fact, the ghdl simulation tool is written in Ada.)

What is the netlist file format?
If the goal is simulation, the output of the process is something that can be processed by a standard compiler (like gcc or llvm) or executed by a pseudocode interpreter. See, for example, what is done by ghdl.

Converting VHDL to Verilog using GHDL
Maybe you could try to minimize your example to a MWE (minimum working example that demonstrates the issue) and then do a bug report against GHDL at https://github.com/ghdl/ghdl/issues
Try a question here: https://github.com/ghdl/ghdl/issues . I have only used GHDL for VHDL, and it worked well for what I was doing with it, but the creator/chief maintainer(?) (Tristan Gingold) should be able to set your issue straight in a short while, and he is pretty active on github.

ghdl, how to include math_real?
replying to myself: I just installed this nightly on a Win10 box and it seems to "work" based on minimal tests. Note that you need to install MinGW.
