Abstract- As the demand for low-cost electronic systemsncreases, increasing wiring density/reducing printed circuiboard (PCB) laver count becomes inevitable. This reality limitsthe PCB routing layer options of high-speed input/output (/O)signals, making it Iore difficult to Ieet the next-generationproduct's performance targets. For example, using denselywired Inicrostrip routing on a PCB helps reduce laver count. bumicrostrip routing suffers from perforinance degradation dueto increased far-end crosstalk(FEXT)."Tabbed lines"havebeen proposed to reduce or eliminate FEXT. In this paper wewill present an introduction fo tabbed lines and their applicationto crosstalk mitigation and impedance management. Followingthat, simulation results are presented showing improvednemory bus performance on densely routed Microstripchannels implemented with tabbed lines
