Add Support for Sipeed Tang Nano 20k #390

Closed wireboy5 closed 3 months ago

wireboy5 commented 3 months ago

This pull request adds basic support for the Sipeed Tang Nano 20k FPGA Development board, including for the Gowin GW2AR-18C chip used by the Tang Nano.

This pull request depends on the changes to the oss-cad-suite package in pull request FPGAwars/tools-oss-cad-suite#8.

Additionally, this pull request adds the fpga_model scons flag, which contains the full name of the FPGA, as required in the call to nextpnr-himbaechel.
