Power & Signal Integrity for Board Design

Start Date: 06/06/2023
Course Overview
Learn when and how to apply power & signal integrity techniques to high-speed interfaces between components. This comprehensive course combines design techniques and methodology with relevant background concepts of high-speed bus and clock design, including transmission line termination, loading, and jitter.
You will work with IBIS models and complete simulations using Mentor Graphics HyperLynx. Other topics include managing PCB effects and on-chip termination. This course balances lecture modules with instructor demonstrations and practical hands-on labs.
Level:

Lab Description:
Lab 1: Invoking HyperLynx – Become familiar with signal integrity tools. Use HyperLynx for schematic entry, modeling, and simulation. Modify a standard IBIS model to define a driver and then use its stackup editor to define a PCB.
Lab 2: Reflection Analysis – Define a circuit and run various simulations for effects of reflection.
Lab 3: Crosstalk Analysis – Using simulation, analyze circuit topology and PCB data for strategies to minimize crosstalk.
Lab 4: Power Prediction – Estimate initial power requirements using an Excel spreadsheet, then use XPower Analyzer to accurately predict board power needs.
Lab 5: I/O Pin Planning – Use the PlanAhead software to identify pin placement and implement pin assignments.
Lab 6: Thermal Design – Determine maximum junction temperature and calculate acceptable thermal resistance
