Tang nano 20K

[dev-hack95]

Is there any support available for tang nano 20k i.e GW2AR-18

Interesting wording of the question, if you are talking about image generation support for the board, then yes - check out the compilation in Apicula's examples : https://github.com/YosysHQ/apicula/blob/master/examples/himbaechel/Makefile.himbaechel#L221-L243

If you mean support in the sense of “I don't have such-and-such primitive working”, then I can look at an example in Verilog (normal, not System). 😉

i have tried nextpnr-gowin and the chip-db is not present for tang nano 20k or any related code i am new to fpga any prebuilt solution using arch or apt packages and himbaechel is broken

To avoid theorizing about Arch (I don't have it anyway) why don't you join the chat https://matrix.to/#/#apicula:matrix.org and ask @pera directly how he managed to make an AUR package for apicula and flash blinky just an hour ago ;)

Sorry I just saw this message, I wrote a quick guide in case anyone else is struggling a bit with this: https://blog.peramid.es/posts/2024-10-19-fpga.html
(and feel free to email me if you have questions - I don't usually check github notifications)

And just in case you manage to run nextpnr - Tangnano20k is 18C family and TangPrimer20k is 18. Even the official IDE will swear if you manage to call Tangnano20k 18 :)
