Exists Open Source FPGA Tool Chain?
CamperBob: I wish.  FPGA tools, without exception, suck.  No C programmer would put up with compilers and linkers that work the way FPGA synthesis tools do.  Open-source efforts could only improve things.FPGA vendors don't document the details needed to configure their chips at the nuts-and-bolts level, so any FOSS toolchain would have to rely on a sustained reverse engineering effort.
