Sheet Entry Not Linked To Child Sheet

This compiler hint appears when a sheet entry is found not to be matched with a port on the child sheet referenced by the parent sheet symbol. All sheet entries in the parent sheet symbol must be synchronized (matched) to corresponding ports on the child sheet. The message is displayed in the Messages panel in the following format:

Sheet-Entry SheetEntryName not matched to Port at Location,

where

SheetEntryName is the name of the sheet entry associated with the parent sheet symbol

Location is the X,Y coordinates for the sheet entry's electrical hotspot.

Recommendation

This issue can arise for a number of reasons:

• The corresponding port for the sheet entry does not exist
• The corresponding port for the sheet entry exists but with a different name
• The corresponding port for the sheet entry exists but with a different I/O Type.

Use the Compile Errors dialog to cross probe to the sheet entry in question. Right-click on the parent sheet symbol and choose Sheet Symbol Actions » Synchronize Sheet Entries and Ports from the menu that appears. This will give you access to the Synchronize Ports To Sheet Entries dialog for that sheet symbol.

Use the dialog to match the sheet entry in question to the required port. If the port does not exist, you can create it directly from the dialog. Where the port exists but name and/or I/O Type differ you can determine, as part of the match, whether the name and I/O Type to be used comes from the sheet entry or the port.

For more detailed information, refer to the area for Synchronizing Sheet Entries and Ports, in the Sheet Symbol section of the Schematic Editor and Object Reference.

Notes

When the sheet entry and port exist but have different names and/or I/O Types, there will be a corresponding error message stating that the port is not matched to a sheet entry. Synchronizing the sheet entry with the port will clear both errors.
