Advanced EM Concepts and Features in Microwave Office

Apr 30, 2019 to May 1, 2019
Event location: 
Parsippany, NJ

This two-day course focuses on concepts and features in the Microwave Office circuit design environment. The first day highlights important concepts the designer needs to understand for successful simulations. Various tradeoffs in settings of the AXIEM planar method-of-moments (MoM) and Analyst 3D finite-element method (FEM) EM simulators based on physical principles will be explained. The second day presents useful features in Microwave Office software that help designers with layout and simulation control. Topics discussed will include using parameters for making EM models, use of PCells, and using multiple PDKs. Advanced extraction control will also be discussed.

Day 1: Concepts - Ports, Boundaries, and Meshing

Four major areas will be discussed: ports, boundary conditions, meshing, and how to know if an answer is correct. For each area, the physics and mathematical principles underlying the issues will be briefly discussed and common situations in AXEIM and Analyst will be presented. Concepts will be illustrated with examples in the software.

Topics covered include:

  • Grounding and calibration issues in ports.
  • Advanced ports: differential, grouping.
  • Understanding impedance boundary conditions: common mistakes.
  • Meshing: setting reasonable mesh criteria.
  • Using passivity and energy conservation measurements.

Day 2: Features – Parameterized Layout, Pre-Processing Rules, Multi-Technology

Advanced features in the Microwave Office EM layout environment that are useful for the designer will be presented.  Parameters can be used for control of layout and creation of EM models, which in turn can be used in EM simulation.  Pre-processing rules are used to simplify the geometry before it is meshed.  The Analyst simulator supports multiple technologies.  

Topics covered include:

  • Shape modifiers and parameterization
  • Using PCells
  • Working with pre-processing rules
  • How to use multiple technologies in the Analyst simulator
  • Advanced extraction control

Course Equipment/Hardware:

  • Bringing your own laptop is preferred. If necessary, a laptop can be provided.
  • Special note: 64-bit PCs are required to run the software.
  • Software, licenses, and required training materials will be provided.
