How to create configurable number of inputs/outputs channel.

We are working creating generic model which will have upto 10 input/output bus channels. But based on project we may need anything between 1 to 10 channels. How can we make configurable model which can select the inputs/outputs required.

Hi Suyash,

Creating a configurable model that can have up to 10 input/output channels can be achieved through various techniques. This can involve using Variant Subsystems and Mask parameters by following these steps:

• Create a top-level model that contains the input/output bus channels.
• Convert your Subsystem to a Variant Subsystem by right-clicking in your model and selecting Subsystem & Model Reference > Variant Subsystem. For more information about Variant Subsystems, refer to the following link: https://www.mathworks.com/help/simulink/slref/variantsubsystemvariantmodelvariantassemblysubsystem.html.
• Based on your requirements, add the Variant Conditions under which each variant is active. To manage these variants, you can use the Variant Manager application, which provides options to configure and manage variants using a GUI. More details can be found here: https://www.mathworks.com/help/simulink/ug/variant-management-overview-example.html.
• Add Mask parameters in the top-level model to provide options for users to specify the number of input/output channels. Ensure that the Mask parameter is linked with the Variant condition. More information can be found here: https://www.mathworks.com/help/simulink/ug/approaches-to-control-active-variant-choice-of-a-variant-block.html.

By employing these strategies, you can create a model with a configurable number of input/output bus channels.
