Abstract: If we can count on anything, we can count on signaling rates going faster and faster for PC boards. We know from our experience that when electrical signaling rates reach 1 GB/S and beyond on conventional FR4 based printed circuit boards, high-speed design, analysis and layout cannot depend on the standard rules of thumb. The rules have to change. This paper will discuss the implications of high signaling rates and how this will effect your board design cycle. Specific attention will be placed on general design concerns, on analysis and simulation issues and layout challenges.
