Using the IGNORE_PROP property to ignore the DEVICE property on your design Migrating a PCB design database created in OrCAD Layout and prepare it for use within PCB Editor To perform the setup and migration tasks, see Layout to PCB Editor Migration Guide on Cadence Support website. Migrating the schematic (.dsn) that was in sync with the physical design in Layout to a Capture-PCB Editor flow If you have an old design where the Capture schematic (.dsn) was in sync with the physical design in Layout (.max), you can migrate this to a Capture-PCB Editor flow. To do so: 1. Open the 16.6 version of Capture. 2. Select the schematic design in Project Manager. 3. Choose Accessories – Layout to PCB Editor translator – Layout to PCB Editor. 4. Specify the location of the .max file and the directory in which the translated board (.brd) file is to be saved. 5. Select the Update dsn with brd check box. Selecting this check box ensures that changes made to the board are back-annotated on the schematic and schematic is in sync with the PCB Editor board. For example, running this translator changes the value of the footprint property. Unless new footprint value is back-annotated on schematic, further ECOs from schematic to layout will cause component rip-offs in PCB Editor board. Using the IGNORE_PROP property to ignore the DEVICE property on your design In cases, where your design library includes the DEVICE property (an anachronism from previous releases), you can avoid having to remove the property from each part in your library by employing the IGNORE_PROP property. To ignore the DEVICE property on a complete design, define IGNORE_PROP as an environmental/system variable and assign it a value of "DEVICE".
