hi friends
i want to find out at what max rate FPGA can run(theoretically) .
ex: XILINX Virtex 4 FPGA
in virtex-4 data sheet given as
500MHz for Blockram and DSP SLICES
450MHz for PowerPC (for FX FPGA's)
but when i am trying to generate clock from DCM IP Core it showing maximum limit is around 330MHz in high speed mode.
is there any effects of speed grade on operating frequency.
i am bit confused with all this values. please tell me what are the factors do i need to consider to find maximum operating frequency of fpga.
can we drive around >600MHZ data signals as inputs to fpga. where can i findout all these info.
thanking you
