Board Simulation (Impedance and Crosstalk Analysis Using Sigrity X Aurora) The entire purpose of proper constraint management is to make the hardware engineer/PCB designer adhere to design and requirement rules to avoid PCB re-spins. While the Constraint Manager does an excellent task in managing constraints, simulation is the research tool that tells the Constraint Manager what rules need to follow. In this section of the guide, we simulate to test and see how helpful the Constraint Manager is in ensuring we at least know when we are in and out of limits. One of the simulations we can run is IR Drop analysis. To access the simulation features in Presto, go to View – Panels – Analysis Workflows. Note: To use these workflows, you need to have Cadence Sigrity X Aurora installed and it should also be the same version of OrCAD X you are using. For example, if you are using OrCAD X 24.1, then you should have Sigrity X Aurora 24.1 installed as a minimum requirement. You do not need a license for Sigrity X, however. OrCAD X just needs to use the Sigrity X tech stack to execute the simulation. 93 www.cadence.com OrCAD X Constraint Management Guide
