Pin unspecific device planning for printed circuit board layout

摘要

A printed circuit board (PCB) block diagram tool for block diagram level editing of a PCB design abstracted from a PCB physical layout tool is disclosed. The PCB block diagram tool includes a plurality of interface objects, a plurality of block objects and interconnect lines. The plurality of interface objects represents interfaces between components. Each of the plurality of interface objects include a plurality of signal, power and ground signal lines without defined physical assignment to pin or pad. The plurality of block objects represents a plurality of physical objects in the PCB physical layout tool. The plurality of blocks are configured to accept the plurality of interface objects. Interconnect lines connect the plurality of interface objects between the plurality of block objects.
