Running Signal Integrity Analysis in OrCAD X Presto Made Easy

Looking to run Signal Integrity (SI) analysis directly at the layout level in OrCAD X Presto? You can easily do this using the built-in Analysis Workflows powered by Sigrity technology.

OrCAD X Presto provides multiple SI analyses such as Impedance, IR Drop, Crosstalk, Reflection, Return Path, and Decap Placement—all accessible within the layout environment.

To get started, navigate to Electrical Analysis → Analysis Workflows and select the required workflow from the drop-down list. Before running any analysis, make sure to complete the setup using the Design Setup Workflow.

These workflows allow you to analyze either the full design or selected nets, view results as graphical overlays along with tables, identify issues like high coupling or impedance discontinuities, and directly fix and validate them on the design canvas.

Please note that access to Aurora In-Design Analysis requires an Aurora license, and these workflows are not available in OrCAD X Standard.

Once the setup is complete, you can run the required analysis based on your design needs and start optimizing your layout efficiently.
