Training classes and seminars

Contents

What training classes do we provide?

We can provide training on modeling and simulation concepts--ranging from short seminars to multiple sessions of hands-on computer labs. In any case, the emphasis is on understanding how the computation results fit with theory and how to resolve practical problems.

We are familiar with and use computer-aided engineering software, such as tools from Sonnet and Cadence. Sonnet and Cadence each provide basic and current training in the use of their software tools. We add value by adding engineering insight and problem solving.

Presentations and short seminars

We can provide a live presentation on any of the following subjects:

  • Models: getting, maintaining, archiving, and retrieving them

Advanced IBIS model subjects:

  • Building an IBIS model from a SPICE model
  • Precise sending end matching for reflective wave switching
  • IBIS models for GBIT serial data busses
  • IBIS/ICEM power integrity modeling
  • Using simplified models to simulate complex I/O
  • Process flows and tools for Signal Integrity modeling and simulation
  • Design space exploration, sensitivity, and RobustDesign®
  • Power Integrity
  • ElectroMagnetic Integrity
  • Model validation and verification

If you are interested in learning more about our presentations and seminars, please contact Leventhal Design & Communications.

A typical syllabus for multi-session computer aided engineering lecture & lab

We can provide a multiple session course in Modeling and Simulation for Signal, Power, and Electromagnetic Integrity using hands-on computer labs, as outlined below.  Or, we can provide selected portions of the following course outline.

Course Outline:

1. Getting Started
Signing on and starting up a board design in the Cadence tool set: Allegro PCB SI® (APCBSI) (formerly SpecctraQuest® ), and the accompanying modules of APCBSI:

  • Model Integrity® (MI) for SPICE to IBIS model conversion
  • SigXplorer® (SX) for topology signal integrity simulation
  • ConstraintManager® (CM) for guiding CAD layout with design constraints
  • SpecctraQuest® ) (SQ) for routed net signal integrity simulation
  • EMControl® (EMC) for rule checking of bypassing, routing, etc.
  • Specctra Router Interface® (SPIF) for CAD to simulation interaction
  • SigWave® (SW) for post-simulation analysis
  • EMISim® (EMIS) for simulating EMI and lowering emissions
