Improved Post-Layout Flow (QSI/QCD)

The Post-Layout flow in both QSI and QCD has been improved to make the process substantially easier to use. The Padstack/Trace Manager now gives users complete control over their design with a single, table-based view showing all padstacks in the design and allows for entire classes of padstacks or single instances of vias/pins to be viewed and edited. The Back Drill Manager allows users to customize back drilling by net, part, reference designator or padstack, also allowing back drilling to be fine-tuned to specify the stub length for each layer. Via models have been improved to make them more accurate and to support pads on unconnected signal layers. Automated Post-Layout extraction now supports arcs and supports positive plane data in ODB++ databases.
