Explore the groundbreaking SymbiFlow project, a fully open-source toolchain for FPGAs, in this comprehensive conference talk. Discover how SymbiFlow aims to be the "GCC of FPGAs," supporting multiple FPGA vendors and enabling Verilog to bitstream compilation without proprietary tools. Learn about its support for large modern FPGAs like Lattice ECP5 and Xilinx 7 series, opening up possibilities for high-resolution video and multi-gigabit networking. Gain insights into the project's current status, future roadmap, and how to contribute to expanding FPGA support. Understand the impact of SymbiFlow on FPGA development, its documentation efforts for FPGA bitstreams, and the potential for open-source communities to participate in hardware innovation. Delve into the presenter's background and the importance of FPGAs in the context of Moore's Law and RISC-V.
