Analog Insydes 2012, the new release of the software tool for symbolic modeling and analysis of analog circuits, contains a large number of improvements to support the design of modern circuits. The enhanced functionality facilitates even more extensive analyses of the considered circuit and extended insights into its behavior. With this knowledge, problems can be solved that are not feasible using purely numeric methods. Thus, Analog Insydes 2012 accelerates the design process and contributes significantly to the optimization of analog circuits. Furthermore, many new features allow a more efficient handling of modern circuits.
The most important improvements of Analog Insydes 2012 are listed below:
- Create circuit schematics on click
- Analog Insydes 2012 offers a fast and user-friendly interface to the recently developed Analog Insydes Schematics Creator.
Fraunhofer ITWM created this graphical user interface for drawing circuit schematics exclusively for the users of Analog Insydes.
They can generate and manipulate wiring diagrams of default and custom components. For this purpose the tool imports existing netlists, models, and model cards.
Thus, it yields a convenient environment for developing complex behavioral models with just a click.
The Schematics Creator is freely available at www.analog-insydes.com.
- Binaries on!
- Analog Insydes 2012 introduces fast and easily accessible platform-specific binaries supplementing its specialized numeric algorithms for solving circuit equations.
This speeds up all steps of the design flow, which depend on simulation results like behavioral model order reduction.
Being available for Windows, Mac OS X, and Linux, the high-performance external routines are fully integrated into Analog Insydes using Mathematica's MathLink interface.
- Set up testbenches
- The new concept of multiple testbenches for a device under testing (DUT) facilitates user-friendly switching of testbench layouts.
By quickly simulating devices in different setups, Analog Insydes generates reduced behavioral models that are valid for multiple testbenches.
This also allows you to easily export reduced behavioral models in hardware description languages like VHDL.
- Identify sequential equations automatically
- Analog Insydes 2012 broadens the benefit of the previously established sequential equations concept.
Having been introduced for improving simulation speed and stability, this feature partially utilizes structural information encoded using a special equation setup.
The latter had previously been tied to Analog Insydes' model library only. Using the new command IdentifySequentialEquations you can apply the improved procedures to custom models.
No further knowledge of the sequential equation syntax is necessary, which significantly accelerates the overall design flow.
- New model export filters
- Analog Insydes 2012 adds two new filters for exporting behavioral models to external simulators:
the Spectre Compiled Model Interface (CMI) and the hardware description language Verilog-A.
- New LTSpice import filter
- Analog Insydes 2012 provides a comprehensive import functionality for netlists of external simulators.
The list of import filters is extended by an interface for LTSpice netlist reading.
The interface includes an extensive library of new LTSpice device models (like VDMOS or OTA) for analyzing analog circuits created using LTSpice.
The most important improvements of Analog Insydes 2011 are listed below:
- Symbolic handling of transient systems
- Analog Insydes provides all components for generating transient, parametrized models that keep track of the dynamic attributes of the circuit.
Furthermore, mixed symbolic-numerical techniques for reducing transient nonlinear systems are implemented.
Together with the well-established small-signal and large-signal-based model reduction procedures, these methods allow the analysis of the complete static and dynamic system behavior.
Finally, interfaces for exporting transient behavioral models are provided.
- Enhanced model order reduction
- The innovative mixed symbolic-numerical model reduction procedure is improved to handle more complex linear and nonlinear systems of equations.
The resulting models are generated in a more compact form to be most suitable for meaningful analyses and accurate simulations.
- More efficient simulations
- The Analog Insydes device models support a new sequential equation structure. It reduces the system complexity of the resulting analog circuits without any loss in the model accuracy. Thus, a more efficient numeric evaluation significantly accelerates solving and simulating.
Additionally, the compact symbolic formulation contributes to the computational robustness so that large industrial-sized systems can be simulated.
- New data objects
- Analog Insydes possesses a large number of new and improved data objects. These allow for a standardized handling of large datasets and
prevents losing track during the Analog Insydes session.
- Extended model library
- Besides many modern AC and DC models, the BSIM3v3 small-signal and large-signal model is also added to the Analog Insydes library.
This allows the design of modern analog circuits as well as the analysis of their specifications.
- User-definable interfaces
- Analog Insydes contains many interfaces for netlist import and simulation data import and export.
Additionally, the new release allows for user-definable interfaces, which enables Analog Insydes users to import and export netlists
and simulation data of custom formats in order to use them in Analog Insydes.
- New documentation
- The documentation of Analog Insydes is adapted to the new Mathematica design and thus is usable in Mathematica 6, 7, and 8.
Furthermore, many function descriptions are extended and new functions are added.
The most commonly used workflows are commented in new demo files and tutorials.
- Robustness improvements and compatibility
- Besides the improvements described before, the stability of several algorithms is increased and the usability of Analog Insydes in the new Mathematica 8 is established.
Analog Insydes continues to provide new and improved features. A few
highlights are listed below.
