Simulation Documentation

Steps, tutorials, and examples for using the design simulation and analysis tools and features available in Advanced Design System. This documentation is also accessible via the Help button in dialog boxes.

Circuit Simulation

Details on using circuit simulators (DC, AC, S-parameter, harmonic balance, gain compression, large-signal S-parameter, Circuit Envelope, and transient/convolution). Includes application-focused examples for setting up and running simulations.

Agilent Ptolemy Simulation

Details on using the Agilent Ptolemy simulator, which is used for signal processing simulations. Includes parameter, data, and theory of operation details, as well as information on cosimulation and building user-compiled models.

Tuning, Optimization, and Statistical Design

Details on using several ADS simulation features common to both Analog/RF systems and signal processing. Includes information on Tuning to view the effects of changing parameter values without re-simulating, Optimization for automatic performance optimization based on a variety of optimizers, and Statistical Design to provide yield analysis and optimization.

Analog/RF User-Defined Models

Instructions for developing Analog/RF user-defined models using the Model Development Kit, Symbolically Defined Devices (SDDs), and Frequency-domain Defined Devices (FDDs). For signal processing user-defined models refer to Agilent Ptolemy Simulation.

Digital Filter Designer

Details on using a specifications-based software tool to design, simulate, analyze, and generate coefficients for high-quality digital filters. Includes information on generating AEL code and schematics for simulation using ADS along with information on optimizing features that help to minimize bitwidth in point filter implementations.

Momentum

Details on using layout designs to set up and perform electromagnetic simulations on passive, planar circuits. Includes information about viewing and analyzing various types of simulation data in Momentum Visualization, and improving circuit performance using Momentum Optimization.

SPICE Model Generator

Details on using the SPICE Model Generator to convert S-parameter data into an approximate equivalent model in SPICE format.

HDL Cosimulation

Details on using the HDL Cosimulation tool, which enables you to simulate components represented by a hardware description language (HDL) in the same schematic with Agilent Ptolemy components.

ISS Cosimulation

Details on using the Instruction Set Simulator (ISS) Cosimulation for Texas Instruments DSP tool, which enables you to perform hardware/software co-design with Texas Instruments DSP chips or cores.

Model Composer

Details on using an EM-based tool to create multidimensional, parameterized, passive planar components with EM accuracy and generality at traditional circuit simulation speed.

Note: The list of simulation manuals displayed above is updated when you install ADS using the custom install option. The list of simulation manuals displayed on the left reflects all manuals available with a complete install of ADS.
