cpu,fpga, clock, dac, initialize sequence

Started by Unknown August 2, 2008
i'm dealing a board which has cpu,fpga, clock, adc etc. onboard.
the clock is for board timing for both the fpga and adc.

the init sequence was to load the fpga logic first, then the clock,
then the adc.
but fpga guys say it's wrong. should i init clock and adc first, then
the fpga?
what's the point here?

It's hard to see what you you should do in which order without more information on the system. What "clock", what "adc"? Is the FPGA in any way involved in the initialization of these circuits? If not, what is? A microcomputer? What sort of fpga? I'm guessing the "fpga guy" knows more about how the system should come up... Regards, Gabor

The point is that the embedded programmer has to read the hardware manual first and/or talk to the hardware designer. Asking generic questions here won't help! /Mikhail
