USING SYSTEMS DESIGN METHODOLOGY TO MANAGE COMPLEX PCB DESIGNS

摘要

Today's PCB designs span a wide gamut. Designs may be as simple as a small PCB in a garage door opener or kitchen appliance, or as complex as dozens or hundreds of interconnected boards in a blade server, or it may be both small and complex, such as a smartphone. Those designs at the complex end of the spectrum push a number of design envelopes. Size is miniaturized to the extent that signal integrity and thermal management become issues. Speed is maximized to the point that tools once reserved solely for RF use are now required for PCB analysis. And then there is the problem of managing all the interconnections among this system of PCBs.
