Document Table of Contents Wildcard Support in Design Partition Scripts

When applying constraints with wildcards, note that wildcards are not analyzed across hierarchical boundaries. For example, an assignment could be made to these nodes: Top|A:inst|B:inst|*, where A and B are lower‑level partitions, and hierarchy B is a child of A, that is B is instantiated in hierarchy A. This assignment is applied to modules A, B, and all children instances of B. However, the assignment Top|A:inst|B:inst* is applied to hierarchy A, but is not applied to the B instances because the single level of hierarchy represented by B:inst* is not expanded into multiple levels of hierarchy. To avoid this issue, ensure that you apply the wildcard to the hierarchical boundary if it should represent multiple levels of hierarchy.

When using the wildcard to represent a level of hierarchy, only single wildcards are supported. This means assignments such as Top|A:inst|*|B:inst|* are not supported. The Quartus® Prime software issues a warning in these cases.
