how can we advise you based on such little information?

Are you struggling to figure out what reference/ground to use for your signals?

What ground does the source use? what ground does the recipient of the signals use?

AFAIK Thats what defines which one to use.

Thanks for the reply.

In my board the source gnd is GND but my brd contains 8 devices and the analog signals from each site get their own AGND return path like AGND1, AGND2, AGND3..etc also my brd contain lot of relays so i want to confirm that whether i give the AGND as the return path for Relay control signals..

Thanks for your help
