Description
This course teaches you how to use the Allegro® PCB SI tool to successfully develop and drive design rules for high-speed designs. You will learn to develop high-speed design rules using Allegro PCB SI XL and then add the resulting physical and electrical constraints to the design through topology templates. These constraints are then used to drive the routing of nets on the printed circuit board. You will perform pre-route and post-route signal simulations to analyze the PCB for reflection, simultaneous switching, crosstalk, and other high-speed design factors.

Course Contents and Time Table
In this course you will learn to:

- Create, extract, and explore topologies.
- Execute Solution Space Analysis.
- Create an electrical constraint set.
- Use constraints to drive placement and routing.
- Run post-route DRC check.
- Use template revision to update the ECSet applied on the nets/bus.
- Analyze the routed board design for signal integrity.
- Create a DesignLink between boards and use it to run multi-board simulation.
