Ok, that's nice, will save a global clock net.
Forgive my ignorance, but where can I find documentation about that ? Is at a half flipflop or a 1-or-2 fliflop ? :-)
I also would appreciate pointers to some good FPGA design tutorial. I can find VHDL tutorials all over the net, but they only cover the basics, not the design methodology. I haven't been able to find a good book about it.
