On-Chip Driven
Signal Integrity

Course Overview

This hands-on course is designed for new or current Ansys CSM users who may want to refresh their skills or get training on the following topics:

  • CSM flow overview
  • Typical on-chip driven DDR system SI analysis, including IO Modeling.
  • High-Speed 2.5D/3DIC Signal Integrity Flow, including high accuracy interposer Modeling.
  • PI induced SI analysis flow, PI and SI co-analysis.
  • Early design optimization flow with optiSLang metamodel.


  • Basic understanding signal integrity analysis is expected.

Teaching Method

Self-paced slide presentation and computer practical sessions to validate acquired knowledge. Emphasis is placed on tool background & methodology as well as workshops.

Learning Outcome

Following completion of this course, you will:

  • Gain an understanding of CSM modelling and flows, as well as a basic proficiency of how to run the tool for different analyses.
