Yosys Fronts for Xilinx ISE
https://hackaday.com/2019/12/13/yosys-fronts-for-xilinx-ise/
We always marvel at how open-source tools can often outstrip their commercial counterparts. Yosys, the open-source tool for Verilog synthesis, is a good example. Although the Xilinx ISE design suite is something close to abandonware, a lot of people still use it because it supports older FPGAs the newer tools …read more (https://hackaday.com/2019/12/13/yosys-fronts-for-xilinx-ise/)
