New utility available: nettovqm converts a VPR format netlist to the format needed by Altera's Quartus CAD suite, letting you interface VPack output to a commercial CAD system.
VPR is part of the SPEC 2000 suite of computer benchmarks (the standard benchmarks used to determine the speed of various workstations). I have found it to be a good predictor of the speed of commercial FPGA CAD tools on various computer hardware as well. Results are here.
