I am wondering how to add a new BGA in the central library for example BGA with 292 pins in the central library. One way is to create a new cell in library manager, define padstack for each of 292 pins in cell editor and in parallel make a new symbol for DxDesigner. Finally connect the cell and symbol by creating a new part in library manager. But working with 292 pins is a lot of work. Is there any efficient way to add new BGA part / package for ADC12D1800 ?
