![]() This pipeline of yosys, arachne-pnr and icestorm now supports two FPGAs, as presented below. For the meantime, it is installed as easily as one types "pip install litterbox". This Python package is not yet packaged for Debian but likely will once we have a CAT-Board at our disposal. Litterbox - for the CAT-Board, a build-yourself FPGA Hat for the Raspberry Pi. preparing the bitstream for the FPGA, and transferring it to the FPGA, uses:įpga-icestorm - for the Lattice boards, using libusb/libftdi The output is a netlist describing how all cells are connected together in BLIF format.Īrachne-pnr - for placement and routing of the netlist. Yosys - for logic synthesis of Verilog code. The pipeline employs the following tools: Introduction to the Open Source FPGA toolchain short or by Clifford Wolf For a convincing video that these devices and the Open Source development tools are useful, see: ![]() There is now a complete Open Source tool chain for some FPGAs from Lattice Semiconductor.
