Gowin EDA (Linux) #

Installation #

To execute bin/gw_eda rename lib/librfreetype.so to something else.

Next you need to install or compile openFPGALoader to load the bitstream to SRAM or Flash.

License #

For the license you can use the education edition of the Gowin EDA, or apply for a free license on the gowin website. In alternative you can use the public license server of sipeed:

• IP: 43.128.7.128
• Port: 10559

Be aware that some public wifi networks block access to these ports.

Use #

Just launch ./bin/gw_eda from the terminal.
