Mismatched Bus or Wire Object on Wire or Bus

This compiler hint appears when a wire object is incorrectly connected to a bus, or a bus object is incorrectly connected to a wire. For example a sheet entry, A, might be connected to a bus, but the correct bus label syntax (e.g. A[0..1]) has not been entered for the sheet entry's name. In effect, the sheet entry is a single signal (or wire) object that is now erroneously connected to a bus. The message is displayed in the Messages panel in the following format:

ObjectIdentifier at Location placed on an ObjectType,

where

ObjectIdentifier represents the mismatched object, which can be either a bus or wire object (e.g. pin, port, power port, sheet entry, net label, off-sheet connector). The identifier will appear in one of the following two formats:

• for a bus - Bus Object Name (e.g. Bus Net Label GND_BUS[..])
• for a wire - Wire Object Name (e.g. Wire Port TXD)

Location is the X,Y coordinates for the object's electrical hotspot

ObjectType is the object on which the offending object has been placed - either a wire or a bus.

Recommendation

Use the Compile Errors dialog to quickly cross probe to the offending object. To resolve the issue, consider the following:

• Is the connection correct - i.e. should a bus connecting to the object really be a wire and vice-versa.
• Is the object defined correctly. For a bus object, ensure that the object's name is specified using the correct bus syntax - in the form Name[LowIndex..HighIndex] or Name[HighIndex..LowIndex]. For example a byte-wide data output port might be specified as DAT_OUT[7..0]. For a wire object, ensure that the object's name defines a single signal and is not defined using bus syntax.
