/dev/ttyUSB0 doesn't exist

[arruk]

I'm a beginner in the FPGA world and I was trying to synthesize some of the examples, beginning with the UART one. So i downloaded the Gowin EDA Educational, synthesized the UART and programed it using the Programmer tool. But after, i was looking for /dev/ttyUSB0, to validate the communication, and it wasn't in the /dev/ directory. Is there a mistake I'm making? By the way, I never had used UART communication, so i don't really know the best way to do it, and i was going to use stty just with cat, is that a good choice?

Thanks.
