Illegal bus range value BusLabel at Location,

where

Recommendation

Use the Compile Errors dialog to quickly cross probe to the offending net object (e.g. net label, port, sheet entry, etc) whose bus syntax is defined incorrectly. The correct syntax should appear in one of the following formats:

NetName[LowerIndex..UpperIndex]

NetName[UpperIndex..LowerIndex]

LowerIndex and UpperIndex can be zero or a positive integer, but can not be the same value.
