Fast frequency domain crosstalk analysis for board-level EMC rule checking and optimization

A fast and accurate method for analyzing frequency domain crosstalk between signal lines in printed circuit boards is described in this paper. An integrated parasitic extraction and crosstalk analysis methodology has been employed since the parasitic elements are essential for the crosstalk noise analysis. The implementation of the integrated extraction and crosstalk analysis requires computation time of the order of milliseconds, which makes the technique suitable for EMC rule checking and EMC/crosstalk aware board level optimization. Trend analysis for variation of crosstalk noise with separation between the signal lines, for both striplines and microstrip lines, has been presented.
