MIXED-SIGNALSIMULATION

System Simulation Software for Multi-Domain DesignSimplorer is a multi-domain simulation software program that enables engineers to model, simulate, analyze and optimize com-plex systems including electromechanical, electromagnetic, power and other mechatronic designs. Using Simplorer’s powerful model-ing features and communication backplane technology, engineers are able to construct virtual prototypes of all aspects of a system including the electronics, sensors/actuators, motors, generators, power converters, controls and embedded software. This enables engineers to investigate system functionality and performance and to verify overall design. The result is a dramatic reduction in development time and cost, increased system reliability and performance optimization.

Applications• Power Electronics• Electric Motors and Drives• Automotive Electronics• Mechatronic Systems• Industrial Automation• Hybrid-Electric and Plug-In Hybrid Propulsion

KEY BENEFITSSystem Design – Simplorer offers multiple modeling techniques including circuits, block diagrams, state machines, equation level, and modeling languages such as VHDL-AMS, SML (Simplorer Standard Language), and C/C++. These can be used concurrently allowing engineers to easily model analog, digital, and mixed signal multi-domain designs. This flexibility eliminates the need for error-prone mathematical transformations and model analogies often employed by single-domain simulation tools.

Physics-based modeling – For system component models requiring the highest level of accuracy, Simplorer provides a direct link to Ansoft’s industry-leading electromagnetic field simulation software: Maxwell®, Q3D Extractor®, RMxprt™, and PExprt™. The coupling technology and the model reduction techniques provide the capability to incorporate detailed physics based models with Simplorer.

Simulator Performance Technology – Simplorer’s unique simulator coupling and co-simulation technologies utilize a data exchange backbone, which connect to optimum simulators with numerical algorithms specifically tuned for the multi-domain nature of dynamic systems. These technologies allow users to create high fidelity models across multiple domains, at different levels of abstraction, and simulate the entire complex system.

Co-simulation – C/C++ programs, MATLAB®/Simulink®, Mathcad® and other specialized programs can be directly integrated into Simplorer. This allows users to utilize customized code and existing feedback/control legacy design. The direct integration of models in their native environment avoids model translation, saves design time and allows communication and model exchange across departments and between suppliers and OEMs.

Integrated Development Environment – Simplorer provides a powerful environment to develop virtual prototypes that can be shared among hardware and software design groups allowing users to simulate hardware and execute the software.

Statistical Analysis and Optimization – Simplorer includes parametric, optimization, sensitivity, statistical, and tuning analysis capabilities. These advanced analysis capabilities allow users to optimize the design based on a set of performance measurement criteria and provide insight into design variations and “trade-offs.” Statistical analysis has fully integrated the SAE VHDL-AMS Statistical Package

Distributed analysis – Simplorer can leverage available computing power with distributed analysis options for fast turnaround of your largest designs.

RMxprt™ is a versatile software program that speeds the design and optimization process of rotating electric machines. With RMxprt, users can calculate machine performance, make initial sizing decisions, and perform hundreds of “what if” analyses in a matter of sec-onds. As the entry point for the Ansoft motor and drive design methodology, RMxprt automatically produces both system-level models and geometric data, allowing the preliminary design to be refined and integrated with power electronic and control circuitry.

Key BenefitsFast designRMxprt offers numerous machine-specific, template-based inter-faces for induction, synchronous, and electronically and brush-commutated machines that allow users to easily enter design parameters and to evaluate design tradeoffs early in the design process.

Performance metricsCritical performance data, such as torque versus speed, power loss, flux in the air gap, power factor and efficiency can be quickly calculated.

Robust calculation methodsRMxprt uses classical analytical motor theory and equivalent magnetic circuit methods to compute performance metrics for a specific machine design and accounts for nonlinear magnetic characteristics and 3D effects, such as skew and end-turn.

Model pre-processorRMxprt is a key part of Ansoft’s motor design methodology. In addition to providing classical motor performance calculations, RMxprt can automatically create 3D and 2D geometry and assign material properties and other necessary problem definition data necessary to perform rigorous finite element analysis on the de-sign using Maxwell®.

Wire libraryRMxprt includes a comprehensive database of ANSI and IEC wires.

High-fidelity system modelsRMxprt creates high-fidelity, state-space system models incor-porating machines’ physical dimensions, winding characteristics and nonlinear material properties. Engineers can use the resulting behavioral model to explore electronic control topologies, loads, and interactions with drive-system components in Simplorer®.

Convenient design sheet outputDesign sheets list all the relevant input parameters and calculated parameters and graphically display waveforms including current, voltage, torque and back EMF as well as a detailed winding lay-out. RMxprt also can output Excel-format design sheets based on the user-defined template.

Design optimizationRMxprt can perform hundreds of “what if” analyses in a matter of minutes, making it a valuable tool for designers needing to make initial sizing and material decisions quickly.

Powerful scriptingRMxprt can be integrated with third party development programs through scripting languages such as VB script, Tcl/TK, JavaScript®, Perl, Excel and MATLAB®. This allows users to customize the design flow and leverage internally developed programs and historical data.

EMI-circuit co-simulationDynamic links to Ansoft Designer® and Nexxim® create an advanced design flow ideal for predicting signal integrity perfor-mance. Designers can easily investigate the effects that electrical parasitics have on circuit performance.

3D solid modelingQ3D Extractor includes a full-featured solid modeler for creating 3D models of connectors, vias, wire bonds, solder balls, signal traces, and power and ground planes. With the addition of AnsoftLinks™ for MCAD, users can directly import ProE, STEP and IGES fileformats.

InteroperabilityWith the addition of AnsoftLinks, Q3D Extractor is tightly integrat-ed with EDA layout design tools from Cadence, Mentor Graphics,Synopsys and Zuken.

Multiprocessing and Distributed Analysis capabilityQ3D Extractor leverages available computing power for fast turnaround of detailed parasitic extraction even on large design layouts.

Robust algorithmsFor 3D structures, Q3D Extractor includes an RLCG parameterextractor based on the Method of Moments (MOM) with the FastMultipole Method (FMM). For transmission lines and cables, it includes a 2D Extractor tool based on the Finite Element Method (FEM) that will extract frequency-dependent per-unit-length RLCG parameters.

EMI/EMC for high-power applicationsQ3D Extractor can extract parasitics from high-power bus bars and cables and input to Simplorer® to study EMI/EMC of the system.
