Stephen, If you plan on managing your Diff Pairs on the Allegro side using the auto generate functionality then they will not be effected when importing a new tel file (3rd Party Netlist). 3rd Party netlist will only append or change properties in Allegro but will not delete them so the existing Diff Pairs created by the auto generator will only be effected if you redefine them by Diff Pair properties defined in the schematic. Hope this helps, Michael Catrambone UTStarcom, Inc.

If yes, how are you handling all the add/delete diff pairs when importing new tel files? Regards, Stephen Feehan Siemens Communications, Inc. (See attached file: C.htm)
