A few weeks ago, I had the pleasure of presenting a webinar concerning power integrity. It was a primer on power distribution systems and how to address the issue of getting enough charge to high frequency devices. This prompted me to write this blog post and share some of the ideas that you can implement immediately.
Why would you as a PCB designer take on this task of signal integrity screening? Clearly, I am suggesting adding to your already compressed schedule – I can’t deny that fact. And by performing this action, we are departing from traditional placement and routing activities. But hold on, before you switch off – when proposing this action to designers, some have actively told me that they want to increase their value in the design process. Others desire a better understanding of the effects of their routing choices, and a few totally embraced the idea on its own merits – the overall time and money savings for the organization.
You could pick up any PCB or electronics design magazine and probably at least one article will be devoted to some aspect of high-speed digital design; be it routing techniques, signal integrity analysis, electromagnetic compatibility or power integrity. This has now become a mainstream design practice.
