3.3.10.1. Valid Ranges for Parameters in the _hw.tcl File

In the _hw.tcl file, you can specify valid ranges for parameters.

Platform Designer validation checks each parameter value against the ALLOWED_RANGES property. If the values specified are outside of the allowed ranges, Platform Designer displays an error message. Specifying choices for the allowed values enables users of the component to choose the parameter value from controls in the parameter editor GUI, instead of entering a value.

The ALLOWED_RANGES property is a list of valid ranges, where each range is a single value, or a range of values defined by a start and end value.
