Soledad The simplest way is to drop the components and then swap them into the circuit. The simplest is to swap out the IC and then turn on the rats for that IC. Then delete the components with * designation. If you feel real industrious you need to create a hierarchical module in the schematic and a module in Allegro.

Does anyone know how to do this or How to translate this change to the schematic?
