Tabbed Routing Support (QSI/QCD)
State of the art high speed designs are leveraging tabbed routing techniques to shrink trace widths and increase routing densities while still managing trace impedance and crosstalk. QSI/QCD now supports tabbed-routing analysis in both pre-layout, what-if analysis and during Post-Layout PCB extraction. In Pre-Layout mode, QSI/QCD allows the user to both specify and sweep tab height, width and pitch to determine which geometry will work best in a given situation. For Post-Layout, QSI/QCD automatically extracts tab geometries to use with built-in enhanced trace models. These models have shown excellent correlation to measurement without the need for a separate 3D field solver which could take 50-500x longer to run.
