The nextpnr FOSS FPGA place-and-route tool

Project IceStorm provides the first end-to-end open source FPGA toolchain, was originally presented at 32c3, and only targetted Lattice iCE40 FPGAs. nextpnr is the next big step for open source FPGA tools, providing a retargetable open source FPGA place-and-route tool that will enable open source flows for many different FPGAs from many different vendors.
