About SymbiFlow
English (USA)

SymbiFlow


SymbiFlow is a FOSS Verilog-to-Bitstream FPGA synthesis flow for Xilinx 7-Series, Lattice iCE40 and Lattice ECP5 FPGAs. It is under construction and consists of a number of subprojects.

Project X-Ray

Project X-Ray aims at documenting the Xilinx 7-series bit-stream format, a prerequisite to building Open Source tools to generate bit-streams for those devices.

Project Trellis

Project Trellis aims at documenting the Lattice ECP5 bit-stream, so that Open Source tools can be built. Project Trellis currently contains enough bitstream documentation to generate simple test bitstreams - including complete documentation for logic and interconnect tiles, and partial documentation for IO and EBR tiles. Work is ongoing to document more advanced parts of the ECP5 such as PLLs and DSPs.
