Nets with Possible Connection Problems
This compiler hint appears when two objects connected to each other on the same net have mismatched electrical types that could lead to problematic connectivity. The pair of object types considered by this error check can be any combination of pins, ports, or sheet entries. For example an Output Port
connected to a Bidirectional Port
. The message is displayed in the Messages panel in the following format:
NetName contains
ObjectType1 and
ObjectType2 objects (
Reference)
,
where
NetName is the name of the parent net containing the possible conflicting objects
ObjectType1 is the first offending object type
ObjectType2 is the second offending object type
Reference is the identifier for one or both objects (e.g. Port PortName
, Pin PinName
, and Sheet Entry
SheetSymbolName-SheetEntryName
).
Default Report Mode
Error
Recommendation
Use the Compile Errors dialog to cross probe to the offending objects. Determine if the connected objects pose a real connectivity problem and, if so, change the I/O specification for one or both objects accordingly.
Notes
The actual report mode used for a violation of this type is dependant on the specific object types, their electrical I/O types, and the corresponding reporting level defined on the Connection Matrix tab of the Options for Project dialog (Project » Project Options).
The Report Mode setting on the Error Reporting tab of the Options for Project dialog has no affect on the Report Mode setting that appears for a violation of this type in the Messages panel. It is, however, used by the Online (real-time) error reporting, directly within the design workspace. Controls for the Online reporting are available on theSchematic - Compiler page of the Preferences dialog. Note that the Online error reporting for a specific object type-I/O type pairing will not be present if the individual check for that combination in the Connection Matrix has been set to No Report
