Electrical Design, Mechanical Design Incremental Data Exchange in Allegro PCB Editor October 2019 14 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. IDX Filter When exporting IDX incremental data, a filter is available to identify what objects are not to be exported. The objects that are not to be exported should be set before the baseline. It is recommended that once the filter is set, no changes are made to the filter during the remainder of the design process or until a new baseline is established. Changing the export filter during the design cycle will result in unexpected results in the export. As an example, a baseline is imported into Allegro PCB Editor with the default filter values. The Allegro PCB designer moves a placed component defined by the baseline. When exporting, the designer changes the filter to exclude pins from the export. When the GUI for changed objects is displayed, each pin for the component is now displayed as deleted. This occurs because on import of the baseline, the pins for the components were identified as being added to the database and recorded in the baseline data. With the filter set to exclude pins, the pins do not appear in the export which is interpreted as deleted pins. The default filter settings are vias and unplaced components. The Filter can be set by selecting the Filter Options button in the IDX Out form.
