I agree, the power flag is strange but as long as it's only needed for DRC it does not create sources of errors. What I menat was just to use power signals as normal signals, e.g. having a signal called "GND" and a signal called "+3.3V". Reason is that during the development process the voltage sometimes changes, for instance from 3.3V to 3.0V then to 2.8V: Less voltage= onger battery life. With the "standard" setup I have to remove all power devices and have to put new ones in. Using as signal I only have to change the signal name. Good to know about the power device pin-length error, thanks. What changes did you actually do to the symbols?
