Pushing PCB changes back to a schematic in Cadence
Why would I need to back annotate a design?
If you make changes to your design while in PCB Editor (for example, swapping a footprint), you must back annotate (meaning, push changes) from the PCB design back into your original schematic. By doing this update, future changes to the schematic can be forward annotated (meaning, pushed forward) to your PCB design without having to start over from scratch.
Transferring a Cadence schematic to PCB Editor
Introduction
In order to create a PCB, you must first prepare the schematic and check for errors, export a netlist of the schematic, import the netlist into PCB editor, and design the PCB. A netlist is a file that describes interconnections among components in a circuit. This tutorial describes the process of transferring a schematic to PCB Editor. It is assumed that you have a completed schematic (see example, Figure 1) before trying to migrate to PCB Editor.
