At least the stuff I use is licensed. Also, the full synthesize/place/route chain can take a long time, depending on the size of the FPGA and the density of the logic. Most of the stuff I do finishes in under 20 miinutes, but the big FPGAs take days to compile.

Even EMC1 had the tools to make this possible. Jon ------------------------------------------------------------------------- Take Surveys. Earn Cash.
