FOSS Flows For FPGA (F4PGA) project

This is the top-level repository for the F4PGA project, which is a Workgroup under the CHIPS Alliance; consisting of members from different backgrounds, including FPGA vendors, industrial users and academia (see Documentation > Community); who collaborate to build a more open source and software-driven FPGA ecosystem (IP, tools and workflows) to drive the adoption of FPGAs in existing and new use cases, and eliminate barriers of entry.
