Subject: [oc] Query regarding power domains

Hi,

Please disregard my previous mail.

I have two power domains. vmain and vstandby. A
signal sig1 is output of a combinational logic in
vmain domain. It is registered in vstandby domain.
vmain domain can be inactive when vstandby is active

What are the potential problems that can occur on
such a signal? Should any care be taken when designing
this logic. How are signals crossing power domains
generally handled.

Regards
Godwin
