Temperature-Dependent Behavior in Semiconductors

You can enable temperature-dependent behavior in the Simscape Electronics semiconductor device models. This lets you specify how the device behavior changes with temperature, and model heat generation within the device. An additional thermal port is added to the block so you can model heat transfer between the device and the environment. You connect this port to thermal models in the Simscape Foundation library.

Op-Amps

Simscape Electronics provides abstract, non-ideal models of op-amps that simulate quickly and produce similar behavior to models that use a detailed transistor implementation. These behavioral models require far fewer parameter values and enable testing of much larger circuits in less time. You can use them to select circuit parameters to avoid nonlinear effects such as power rail and slew rate limiting during normal circuit operation.

Faults and Losses

Simscape Electronics enables you to verify the robustness of your design. You can inject faults throughout your electrical network and automatically analyze the power dissipated by components in your design.

Introducing Faults

You can introduce faults into your Simscape Electronics models. You can specify the conditions under which components should fail, such as when a current limit is exceeded. You can also specify how the device should behave after failure, such as an open circuit or short circuit. You can use MATLAB scripting to automate the configuration of faults, which enables you to efficiently validate your system against a full set of fault conditions.

Measuring Switching Losses

Simscape Electronics models enable you to calculate the power dissipated by electrical components. This helps you verify that circuit components are operating within their working envelopes. You can perform this calculation at any level of your design, incorporating individual or sets of components. The analysis can be run automatically using MATLAB code to cover specific events within a single simulation or on sets of test scenarios.

Simscape Platform

Simscape is the platform for all Simscape add-on products. In addition to the Foundation libraries, it provides much of the core technology for modeling and simulating physical systems in all domains.

Modeling with Physical Connections

Simscape components represent physical elements, such as pumps, motors, and op-amps. Lines in your model that connect these components correspond to physical connections in the real system that transmit power. This approach lets you describe the physical structure of a system rather than the underlying mathematics. Electrical, mechanical, hydraulic, and other physical connections are represented in your multidomain schematic by lines whose color indicates their physical domain. You can see right away which systems are in your model and how they are connected to one another.

Simscape Platform Capabilities

Simscape Electronics is based on Simscape, which provides much of the core technology and capabilities necessary for modeling and simulating electronic and mechatronic systems. Simscape enables you to:

Simscape Product Family

The Simscape family of products consists of six products that cover many applications. You can combine any set of the Simscape add-on products with the Simscape platform to model multidomain physical systems. The add-on products include more advanced blocks and analysis methods.

Converting to C Code

You can convert Simscape Electronics models into C code using Simulink Coder. Converting Simscape Electronics models to C code enables them to be used for tasks such as HIL testing and optimization where batch simulations are performed. Converting to C code also enables you to protect your intellectual property.

Testing Without Hardware Prototypes

Simscape Electronics models enable you to test embedded control algorithms and controller hardware without using hardware prototypes. In addition to software-in-the-loop (SIL) and processor-in-the-loop (PIL) tests, converting your Simscape Electronics models to C code lets you run hardware-in-the-loop (HIL) tests. This enables you to test embedded controllers without endangering equipment and personnel, and increases your confidence that the system will behave as specified when you connect the controller to the real system.

Running Batch Simulations

Many engineering tasks, such as optimizations and parameter sweeps, require running many sets of simulations. Converting your Simscape Electronics model to C code enables the efficient execution of these tasks. You can accelerate individual simulations and run batches of simulations in parallel over multiple processors or distributed across a computing cluster.

Sharing Models

Simscape helps you make efficient use of your purchased software when sharing models that use Simscape Electronics. It also provides methods of sharing models while protecting your intellectual property.

Accessing Capabilities in Simscape Add-on Products

Using Simscape Editing Mode, Simscape users can perform many tasks on models that use Simscape add-on products even if they have not purchased the add-on products. These tasks include viewing, simulating, and changing parameter values in the model. As a result, your team can leverage advanced components and capabilities from the entire Simscape product family without requiring that each engineer purchase a license for each Simscape add-on product.

Sharing Protected Models

You can share Simscape Electronics models with other users while protecting your intellectual property. You can protect custom components defined using the Simscape language as well as subsystems containing Simscape Electronics components. Sharing these models lets other users run simulations, vary parameters, and convert them to C code, but prevents them from seeing the original implementation.

Simscape in Academia

MATLAB, Simulink®, and Simscape are used at many leading universities. Educators can use modeling and simulation with 3D visualization to engage students with realistic examples and make classroom theory come alive. Using simulation, students can prototype in a virtual environment, which encourages them to try out new designs and to explore the entire parameter space. Simulation enables them to optimize their designs in research projects and student competitions. Because these products are also used widely across industries such as automotive, aerospace, and robotics, graduating students who have experience with MATLAB, Simulink, and Simscape are in demand by employers.
