ID:140007 Region name "<name>" is reserved -- specify a different name

CAUSE: You attempted to name a region with a name that is reserved. If the error occurs after you have manually edited the Quartus Prime Settings File (.qsf) for the project, the associated region is ignored by the Quartus Prime software.

ACTION: If you obtain this message while trying to rename a region within the Quartus Prime software, retry the operation using a different name. If you obtain this message after manually editing the Quartus Prime Settings File, it is important to correct the Quartus Prime Settings File so that the region is recognized in subsequent compilations.
