The parameters are initially determined during the Create and Package New IP wizard by parsing the top-level HDL file. When you want to update parameters from the top-level HDL source file due to a change to the HDL source after packaging, you can re-import the parameters.

When importing parameters from the HDL, the values are determined at the time of import or merge. If a parameter is calculated based on an expression, the expression is evaluated at the time of import. To keep the expression, you must edit the parameter to create the XPATH expression. For more information on editing a parameter, see Editing a Parameter.
