Course Description The Allegro® Sigrity™ PI course covers the Allegro Sigrity PI product, which provides an integrated solution for power delivery analysis, and features integrated Sigrity technology for DC analysis and a Power Feasibility Editor to drive the creation of Power Integrity Constraint Sets. In this course, you run a DC analysis on a PCB to determine the voltage drop seen by the power consuming components on a PCB. You also use the Power Feasibility Editor to select and analyze a set of capacitors and create a decoupling strategy for ICson the board. This strategy is then captured in a power integrity constraint set and is passed back to the design and managed in the Constraint Manager. You also use these power integrity constraint sets to provide placement guidance for placing the decoupling capacitors on the board.
