FPGA : dual clock problem

As our FPGA must communicated with the gumstix using the GPMC bus, 2 clock must be used on the FPGA : GPMC clock for data transfert and, the internal FPGA clock for all the other operations.

To isolate the two clock, we use a dual clock fifo (a altera’s megafunction). Yesterday, Sylvain and I worked all day long trying to make work the fifo (and correcting some problem of simulation … ) in order to turn on LED indicated by the gumstix. It was not a success so, we will keep on working on this problem today.
