8 1. A Short Introduction
1.2 Getting Started
If this is your first contact with Analog Insydes, this chapter will help you to get familiar with
the system. To get an overview of the functionality of Analog Insydes, the first section provides
a list of the most important commands (Section 1.2.1). Next, it is described how to load Analog
Insydes into the Mathematica kernel (Section 1.2.2), and an example application shows one possible
way to use Analog Insydes for solving a specific analysis task (Section 1.2.3). If you have never seen
Analog Insydes before, reading this example will give you a first impression of the system. Finally,
Section 1.2.4 explains how to access the Analog Insydes online help system.
1.2.1 Command Overview
The most important Analog Insydes commands are listed in this section. For each command,
references are given where to find more information. A link to the reference manual (Part 3 of this
book) is given first, followed by links to related topics described in the tutorial (Part 2 of this book).
Interfaces
Analog Insydes provides import and export filters to Eldo, PSpice, Saber, and Spectre. (Chapter 3.10):
ReadNetlist (Section 3.10.1, Section 2.9.2) translates external netlist files (including model cards,
small-signal data, and operating-point information) into the Analog Insydes netlist language.
ReadSimulationData (Section 3.10.3, Section 2.10.2) allows for importing and transforming
numerical simulation data into Mathematica InterpolatingFunction objects.
WriteSimulationData (Section 3.10.4) exports numerical data calculated with Analog Insydes for
further postprocessing in external waveform viewers.
WriteModel (Section 3.10.5) generates behavioral model descriptions of symbolic (approximated)
equation systems.
Netlists, Circuits, and Models
In Analog Insydes, analog circuits are expressed in terms of Netlist, Circuit, and Model objects:
Netlist (Section 3.1.1, Chapter 2.2) is the basic data structure which contains the elements of a
flat netlist.
Circuit (Section 3.1.2, Chapter 2.3, Section 2.3.1) is a data structure which combines netlists,
models, model parameters, and global parameters.
Model (Section 3.2.1, Section 2.3.2, Section 2.6.2) is a data structure which defines netlist-based or
equations-based models or subcircuits.
