TinyFPGA BX is pretty good (all open source tooling), but generally everyone has linux tools. edit: unless you meant which one would boot linux best :P Answer i

  Ha, yes I meant tooling. But what if you want to scale your design to a different platform, would the open source tools still work?

    For simulation and formal verification, yes, absolutely. Either Icarus Verilog, Verilator or SymbiYosys have been used for large commercial designs. For synthesis, the only FPGAs families currently supported by an open source flow are the Lattice iCE40 and ECP5 [0]. The latter is something you can be decently productive with and can fit quite a bit of logic (think: Amiga reimplementation, PCIe interfacing, etc.). If you'd like to port synthesizeable code from the open source world to the commercial world, this _should_ just work as long as you're willing to rewrite any physical interfacing code (since those depend on hardware blocks available in a particular family) and stick to high-quality Verilog. But that's the same as porting across any other FPGA families. Disclaimer: I work with SymbioticEDA, who develop and provide commercial support for some open source digital logic tooling, like Yosys and Nextpnr.
