Chapter 1: Momentum Basics

Momentum is a part of Advanced Design System and gives you the simulation tools you need to evaluate and design modern communications systems products. Momentum is an electromagnetic simulator that computes S-parameters for general planar circuits, including microstrip, slotline, stripline, coplanar waveguide, and other topologies. Vias and airbridges connect topologies between layers, so you can simulate multilayer RF/microwave printed circuit boards, hybrids, multichip modules, and integrated circuits. Momentum gives you a complete tool set to predict the performance of high-frequency circuit boards, antennas, and ICs.

Momentum Optimization extends Momentum capability to a true design automation tool. The Momentum Optimization process varies geometry parameters automatically to help you achieve the optimal structure that meets the circuit or device performance goals. By using (parameterized) layout components you can also perform Momentum optimizations form the schematic page.

Momentum Visualization is an option that gives users a 3-dimensional perspective of simulation results, enabling you to view and animate current flow in conductors and slots, and view both 2D and 3D representations of far-field radiation patterns.

If you are unfamiliar with Advanced Design System, refer to the Quick Start in the online documentation, and to Schematic Capture and Layout. For information on the interactions between Layout and Momentum, refer to Drawing Tips.

Momentum Major Benefits

Momentum enables you to:

? ? ?

Simulate when a circuit model range is exceeded or the model does not exist Identify parasitic coupling between components

Go beyond simple analysis and verification to design automation of circuit performance

?

Visualize current flow and 3-dimensional displays of far-field radiation

Momentum Major Features

30

Key features of Momentum include:

? ? ?

An electromagnetic simulator based on the Method of Moments Adaptive frequency sampling for fast, accurate, simulation results

Optimization tools that alter geometric dimensions of a design to achieve performance specifications

? ? ?

Comprehensive data display tools for viewing results

Equation and expression capability for performing calculations on simulated data Full integration in the ADS circuit simulation environment allowing EM/Circuit co-simulation and co-optimization.

Momentum Overview

Momentum commands are available from the Layout window. The following steps describe a typical process for creating and simulating a design with Momentum:

1. Choose Momentum or Momentum RF mode. Momentum can operate in two simulation modes: microwave or RF. You can select the mode based on your design goals. Use Momentum (microwave) mode for designs requiring full-wave electromagnetic simulations that include microwave radiation effects. Use Momentum RF mode for designs that are geometrically complex, electrically small, and do not radiate. You might also choose Momentum RF mode for quick simulations on new microwave models that can ignore radiation effects, and to conserve computer resources. For more information comparing the Momentum and Momentum RF modes, see About the Simulation Modes. 2. Create a physical design. You start with the physical dimensions of a planar design, such as a patch antenna or the traces on a multilayer printed circuit board. There are three ways to enter a design into Advanced Design System:

1. Convert a schematic into a physical layout 2. Draw the design using Layout

3. Import a layout from another simulator or design system. Advanced

Design System can import files in a variety of formats.

For information on converting schematics or drawing in Layout, refer Schematic Capture and Layout. For information on importing designs, refer to the manual, Importing and Exporting Designs.

3. Define the substrate characteristics. A substrate is the media upon which the circuit resides. For example, a multilayer PC board consists of various layers of metal, insulating or dielectric material, and ground planes. Other designs may include covers, or they may be open and radiate into air. A complete substrate definition is required in order to simulate a design. The substrate definition includes the number of layers in t …… 此处隐藏：7683字，全部文档内容请下载后查看。喜欢就下载吧 ……
