Parent category: Violations Associated with Buses

Default report mode:

Summary

This violation occurs when at least one index in the syntax for a net associated with a bus is negative in value.

Notification

If compiler errors and warnings are enabled for display on the schematic (enabled on the Schematic - Compiler page of the Preferences dialog) an offending object will display a colored squiggle beneath it. A notification is also displayed in the Messages panel in the following format:

Illegal bus range value <BusLabel> at <Location>

where:

• BusLabel is the defined bus labeling where the illegal value has been detected.
• Location is the X,Y coordinates for the offending bus object's electrical hotspot.

Recommendation for Resolution

With the violation selected in the Messages panel, use the Details region of the panel 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>]
