1. A computer program product, readable by at least one machine, embodying a program of instructions executable by the at least one machine for performing a computer aided design (CAD) method, the method comprising the steps of:
- generating a plurality of individual printed circuit board (PCB) data files, the PCB data files representing PCBs of a computer system; and
processing the plurality of individual PCB data files for taking into account a system-level design parameter of the computer system across more than one of said plurality of individual PCB data files.

Abstract
A computer aided design (CAD) tool takes into account system-level design parameters by considering data from a number of printed circuit board (PCB)-related data files. In one embodiment, the CAD tool takes into account signal path length at the system-level for a computer system comprising more than one PCB. In another embodiment, the CAD tool provides a three-dimensional display for showing how at least one signal path traverses the computer system in going from one PCB to another PCB.
