CAN/Network-Based Signal Integrity



Verifying signal integrity for CAN and other communication network applications that span automotive (ISO 11898-2), commercial vehicle (SAE J1939), agricultural equipment (ISO 111783), and large aerospace platforms (MIL-STD-1553) presents a critical and complex design challenge. Component “recommended use” and standard network configuration guidelines provide for sometimes overly-conservative design margins, while the penalty of weight, cost, and layout constraints that arise from following these rules drives some network developers to look for design solutions that go beyond rote application of design rules.

What You Will Learn

This presentation focuses on an automated simulation-based approach that takes design engineers far beyond the confines of simplistic design guidelines, and with automation that would be impossible to match with prototyping, guesswork, or manual calculations. Analysis will include line loss in long transmission lines, developing a sound termination strategy by analyzing and mitigating reflections from stubs, and simulating the effect of delay on data synchronization processes under the full range of operating conditions and customer-configuration options. Analysis of EMI-causing common-mode currents on differential lines and simulation of transient disturbances (e.g. ESD or lightning-strike) will also be investigated.

About the Presenter

Bill Hargin currently serves as the director of marketing for Mentor Graphics’ SystemVision product line. Previously, as director of marketing for Mentor’s HyperLynx product line, Bill developed a high-speed digital design workshop that has been delivered to thousands of engineers in 30 different countries. Prior to Mentor Graphics, Hargin worked as a signal-integrity consultant with Cognition Consulting. He holds a BSME and master's degree from Washington State University.

Who Should Attend

  • Engineering managers who are concerned about improving quality while reducing design-cycle time
  • System-design engineers who are focused on communication network design of military, aerospace, automotive, commercial vehicle, or agricultural vehicle applications
  • Engineers and managers involved in mechatronic system design - particularly in rapid prototyping environments - where simulation control, setup, and automated analysis of results with Microsoft Excel would be of interest
