Functional and physical isolation

Hi,

Are you sure you mean "physical isolation" and this should be related to "ASIC design".
What do you mean with "power"? (Electrical power, processing power...)

I guess you ´ve read some article or document. Please give a link to it.

In the power domain crossing the isolation cells will be inserted in between power gated domain and always on domain. This is known as isolation. I came across this terminologies when I have discussion with people in PD team

you can think of isolation as making sure things are ok electrically. no current flows from/to the shut off block.
what is meant by functional isolation is not clear to me, I have not come across this term. it probably means that the blocks that are on should not expect any handshake from blocks that are off, or similar communication dependency.
