Missing Child HDL Entity For Sheet Symbol

This compiler hint appears when the link between a sheet symbol and a target HDL sub document is invalid, specifically due to mismatched Entity Parameter Properties. This can occur when:

• A sheet symbol has been placed manually but the VHDLEntity parameter has been incorrectly specified
• You have changed the value of the Entity parameter in the target HDL sub document and you have not updated the VHDLEntity parameter on your sheet symbol.

The message is displayed in the Messages panel in the following format:

Missing HDL Entity: VHDLEntityValue in SymbolFileName in Symbol SymbolDesignator

where

VHDLEntityValue is the parameter value specified for the VHDLEntity on the parent sheet symbol

SymbolFileName is the current entry for the parent sheet symbol's Filename field.

SymbolDesignator is the designator of the parent sheet symbol.

Default Report Mode

Error

Recommendation

Check the sheet symbol's VHDLEntity parameter and ensure that it matches the value in the HDL sub document.
