ID:267007 Trigger condition "<name>" in Signal Tap File contains undefined bus "<name>" with symbol or value "<name>"

CAUSE: In the specified trigger condition of the current Signal Tap File (.stp), you referenced the specified bus with the specified symbol, but the bus does not exist in the signal set. You manually edited the STP File, but the file is invalid.

ACTION: Remove the undefined bus name 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.
