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
https://github.com/YosysHQ/apicula
Project Apicula says "currently supported boards are ... [list of mostly Tang boards]" without qualification.
I wouldn't be surprised to discover that it actually is qualified support, though. Do you think the actual support is low enough that one should avoid those boards for now?
- Project Apicula adds support for DDR SERDES primitives on several GW1 devices.
-
PLL Rates? Can any of the Gowin parts do 1080P?
I actually haven't, since I don't know who they are. That is a good idea though, posted https://github.com/YosysHQ/apicula/issues/169 to discuss the issue, in case someone there might be able to pick it up.
- Project Apicula: added initial PLL support for GW1N-1
-
Minimal build script, and flags for yosys and nextpnr to target GW1N-LV1QN48?
You do not need any gowin software or licensing for the open source toolchain. As the other poster noted, there are a few getting started guides floating around. Alternatively, just swing by the project apicula page and work through their instructions.

Has anyone had any experience with this ultra-cheap Chinese FPGA board - the Sipeed Tang Nano
btw.: there is also a lot of interesting progress going on in the project apicula, the open source tools for the gowin FPGAs.

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

Looking for Recommended Circuit Simulation Software
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

could someone please help me build a circuit for this truth table 🙏
The Digital application can generate a circuit based on a truth table. An example...
