When I manually place a via, change it's signal name, the unrouted nest does not include it as a needed connection for that signal. If I manually route the signal from say an SMD pad to the via, the unrouted nets still shows the unrouted net coming from the SMD pad and as such the DRC indicates that the signal is unrouted.
This plays havoc with a two layer board where I'm using copper pours for ground and power planes on either top or bottom layers. Since copper pours are not recognized as power planes other than on an internal layer, manually routing grounds from the top layer with a via to the effective ground plane on the bottom layer isn't recognized as a completed route. This causes a bit of uncertainty with the DRC as it indicates unrouted signals when in fact they actually are.
Are there better techniques for dealing with these issues?
