Why no one have the answer or have the same question?99.9% of the people on this list have no experience building the firmware or making modifications to it, they just use the as-supplied firmware. The way the fpga code is setup, it's intended to be built with "make" rather than the vendors IDE, so it doesn't surprise me that you get topology-related errors. But that's as much as I know. I've never built it myself. Also, the way FPGA "routers" work, there's a certain amount of Monte-Carlo decision making done in the way paths are laid out. So two different "runs" with exactly the same codebase can yield different (but functionally identical) FPGA binaries. The same thing happens with PCB routers--press the "route" button, it will be very often route the same circuit/physical placement with different lines.
