ID:267008 Mnemonic table "<name>" does not exist in Signal Tap File

CAUSE: The specified mnemonic table does not exist in the current Signal Tap File (.stp). You manually edited an STP File, but the file is invalid.

ACTION: Remove the specified mnemonic table from the STP File. If the file is supplied by a third-party tool vendor, contact the vendor. To avoid this message in the future, Intel recommends using the Signal Tap window to modify STP Files, rather than editing the files manually.
