Crosstalk driven routing advice

This paper examines the feasibility of generating routing advice for interconnects on printed circuit boards (PCBs) at the design stage, on the basis of crosstalk noise requirements and relevant timing information. A set of analytical expressions have been developed to relate physical design parameters, such as the spacing between a pair of coupled signal lines, to the amount of crosstalk noise generated on these lines. Timing windows have been used to define time intervals during which noise on a specific signal line can affect the functioning of the entire system. An algorithm has been developed, based on the above expressions, to estimate the minimum safe spacing between a pair of coupled signal lines, given the crosstalk noise budget and timing information
