Do you mean the resistance from point A to point B of the same net (and that
you think 1 ohm is too large)?
Or do you mean the resistance between + and - rails of a board that is fully
populated with active devices and capacitors (and that you think 1 ohm is
too small)?
Please clarify.
Also please suggest what resistance you would have expected in your case.

Andy
