1.3 What’s New 27
Graphics Functions
New and improved graphics functions
Improved command interfaces for a more comfortable use
Improved User Interface
Improved user interface allows for setting up and running circuit analyses from Eldo, PSpice, or
Saber netlists with as few as three Analog Insydes commands
1.3.3 New in Version 2: A More Detailed Description
The most noticeable changes between Analog Insydes versions 1 and 2 were made to the circuit
description and modeling language and to the way circuit equations are set up, stored, and presented
to the user:
Netlist Format
The circuit description language (netlist format) was extended by functionality for managing device
model parameter sets (model cards), global parameter settings, initial conditions, and multiple
source values for different analysis modes (AC, DC, transient). With these enhancements it is now
possible to represent all netlist and device model information contained in a SPICE circuit description
consistently in an Analog Insydes Circuit object.
The netlist fragment shown below illustrates the use of some new language features. Note that
the unspecific arguments of the keywords Model, Selector, and Parameters in the value field
of the device reference Q1 permit an easy selection of device models and parameter sets at run
time using Mathematica’s pattern rewriting functionality. The model expansion mechanism of Analog
Insydes 2 makes use of this approach to automatically select appropriate device models according to
the specified analysis mode.
