A Complete Open Source Design Flow for Gowin FPGAs

In this paper, we propose an open source design flow for the low cost FPGAs from the company Gowin. Open source design tools are opening the door for custom extensions and modification in the design flow. The proposed design flow which supports almost all Gowin FPGA resources, is based on well-known open source tools, like Yosys and nextpnr, as well as on our proposed open source bitstream generat...
