How to Route and Verify a Differential Pair in Allegro X

Knowing your differential pair should be 100 ohms is one thing. Verifying it actually is before the board goes to fab is another. This video walks through the complete workflow in Allegro X for differential pairs: setting up the PCB stack up, defining differential pairs, setting physical constraints, and routing both traces simultaneously from a single click. Impedance is then verified using Sigrity X Aurora impedance workflow inside the Analyze Workflow Manager.
