ID:138012 Specified partition name "<name>" is invalid. A partition name cannot have more than <number> characters, and must consist of alphanumerical characters, colon (:), underscore (_), and pipe (|) only

CAUSE: You attempted to name a partition using a name that contains more than the maximum number of characters allowed, and/or a name that contains invalid characters. If the illegal name appears in the Quartus Prime Settings File (.qsf), the associated partition is ignored by the Quartus Prime software.

ACTION: If you obtain this message while trying to rename a partition using the Design Partitions Window command, retry the operation using a different name. If you obtain this message after manually editing the project QSF, it is important to correct the QSF so that the partition is recognized in subsequent compilations.
