1.8. Defining Instance Parameters

You can implement instance parameters to test the functionality of your Platform Designer system when using another Platform Designer system as a sub-component of a larger system. A higher-level Platform Designer system can assign values to instance parameters, and then test those values in the lower-level system.

You can use the Instance Parameters tab to define how the specified values for the instance parameters affect the sub-components in the Platform Designer system. You define an Instance Script that creates queries for the instance parameters, and sets the values of the parameters for the lower-level system components.

When you click Preview Instance, Platform Designer creates a preview of the current Platform Designer system with the specified parameters and instance script and opens the parameter editor. This command allows you to see how an instance of a system appears when you use it in another system. The preview instance does not affect your saved system.

To use instance parameters, the IP components or subsystems in your Platform Designer system must have parameters that can be set when they are instantiated in a higher-level system.

If you create hierarchical Platform Designer systems, each Platform Designer system in the hierarchy can include instance parameters to pass parameter values through multiple levels of hierarchy.
