I need to route some length matching signals, but these have series resistors (terminators). Is possible to set a length constrain to a sum of a couple of nets?
That means the sum of the length before the series term and the length after the series term matches one conjoint length constraint.
In CES/Setup/Settings/Discrete Component Prefixes - make sure that RefDes Prefixes are filled in correctly so the system recognizes electrical nets. You can verify that w/the Nets tab. Then enter the values you need in the 'Length or TOF Delay' columns. Tuning should do the trick (you may have to check your Editor Control Tuning settings).
Hope that helps.
