Dave & Frank,
I have worked with several customers in the EE Flow who use the "schematic update" feature to enable a more stream-lined flat design process. They find the ability to update designs by moving dangling nets from fracture A to fracture B is more inline with their existing process & allows them to ease into adopting I/O Designer. It can also be used to modify older designs created before an I/O Designer deployment. Is this a feature that will be introduced into a PADS Flow any time soon?
