How do I add variants in Simulink?
Include Simulink Model as Variant Choice
- Create a model that you want to include as a variant choice.
- In your model, right-click the Variant Subsystem block that contains variant choices and select Block Parameters (Subsystem).
- In the block parameters dialog box, click the button to add a Model block as variant choice.
What is variant subsystem?
Variant subsystems let you provide multiple implementations for a subsystem where only one implementation is active during simulation. You can programmatically swap out the active implementation and replace it with one of the other implementations without modifying the model.
What is a Simulink subsystem?
A subsystem is a set of blocks that you group into a single Subsystem block. Using subsystems: Establishes a hierarchical block diagram, where a Subsystem block is on one layer and the blocks that make up the subsystem are on another. Keeps functionally related blocks together.
How do I use variant subsystem?
Using Variant Subsystems Variant objects association for the Controller subsystem, right-click on the Controller subsystem and select Subsystem Parameters , which will open the Controller subsystem block dialog. The Controller subsystem block dialog specifies two potential variants.
What is virtual and non virtual subsystem?
Nonvirtual subsystem – Control when the contents of the subsystem are evaluated as a single unit (atomic execution). Virtual subsystem – Subsystem is neither conditionally nor atomically executed. Virtual subsystems do not have checksums.
What is Matlab function packaging?
The Function Packaging parameter has these four settings: Inline : Inline the subsystem code. Nonreusable function : Function with I/O passed as global data. Reusable function : Function with I/O passed as function arguments. Auto : Let Simulink Coder optimize based on context.
What does model variant mean?
A variant is the label that is used to describe a particular vehicle. Rather than just having the make and model, it includes more specific data such as engine size, number of doors and the version. E.g. Ford Fiesta (1.25 Zetec Hatchback 5dr)
What are variants used for?
The use of variant blocks in a model helps in reusability of the model for different conditional expressions called variant choices. This approach helps you to meet diverse customer requirements based on application, cost, or operational considerations.
What is the concept of subsystem?
A subsystem is a single, predefined operating environment through which the system coordinates the work flow and resource use. The system can contain several subsystems, all operating independently of each other. Subsystems manage resources.
What is an example of a subsystem?
An example of a subsystem is the way a department works in a larger company. A unit or device that is part of a larger system. For example, a disk subsystem is a part of a computer system. Any system that is part of a larger system; component system.
What is variant control?
Variant controls determine which variant choice is active. By changing the value of a variant control, you can switch the active variant choice.
What are MAAB guidelines?
The MAB Guidelines are a set of modeling guidelines developed by an independent industry working group for the usage of MATLAB®, Simulink®, Stateflow® and Embedded Coder®.
How do you create a subsystem in Simulink?
In the Simulink Editor, double-click and start typing the subsystem type, then select the corresponding block from the menu. In the Simulink Editor, drag a selection box to outline the subsystem that you want to create, then select the subsystem type. Drag a Subsystem block from the Library Browser. Copy and paste a Subsystem block from a model.
How are variants used in a Simulink model?
What Are Variants? In Simulink ®, you can use the variant blocks to create a single model that caters to multiple variant requirements. Such models have a fixed common structure and a finite set of variable components. The variable components are activated depending on the variant choice that you select.
How are variants represented in a subsystem block?
A Variant Subsystem block is a container of variants choices that are represented as Subsystem or Model blocks. The inputs that the Variant Subsystem block receives from upstream models components map to the input and output ports of the variant choices.
When to use a variant subsystem in simulation?
Variant subsystems let you provide multiple implementations for a subsystem where only one implementation is active during simulation. You can programmatically swap out the active implementation and replace it with one of the other implementations without modifying the model.
