OrCAD® Integrated Analysis and Checking is a new, unique environment blending the best
of OrCAD® and Sigrity™ technologies that provides analysis and checking capability entirely
within the PCB Editor framework. Two workflow analysis capabilities for impedance and coupling are now available. The workflows provide guided access to Sigrity analysis with results returned as dockable tables and plots, or as Vision overlays.

Note: The Labs in this section require an installation of the latest Sigrity version. If the required  Sigrity installation is not found there will be error messages and erroneous log file messages reported.

Impedance Analysis Workflow

This Analysis workflow provides impedance data feedback based on Sigrity analysis by either running an analysis or loading pre-existing Sigrity analysis results. Impedance Analysis can be either Net Based – Net, XNet, Bus, Differential Pair – or Directed Group – connections between a start component and end component(s). Analysis results display trace segment or sub-segment canvas color coding reflecting impedance values. In addition, an impedance color gradient bar with sliders is provided to filter impedance values on the canvas, and a detailed impedance results table to filter/sort by net name and impedance values.

Coupling Analysis Workflow

Coupling Analysis provides critical coupling feedback based on Sigrity analysis by either running an analysis or loading pre-existing Sigrity analysis results. Coupling Analysis can be either Net Based or Directed Group similar to Impedance Analysis flow. Analysis results display trace segment or sub-segment canvas color coding reflecting coupling issues. For detailed coupling information, hover the mouse over a trace segment. In addition, a coupling coefficient color gradient bar is provided with sliders for filtering on the canvas, and a detailed coupling results table to filter or sort by net name and coupling related results.
