7.1 NGDBUILD - "ERROR:NgdBuild:455 - logical net 'signal_name' has multiple drivers."


Problem Description:

I receive the following error when running Translate although there appears to be only one driver on a given net (e.g: 'signal_name').

"ERROR:NgdBuild:455 - logical net 'signal_name' has multiple drivers."


A typical occurrence of this error is due to instantiation of macros which include IBUFs in them. For example, IFDDRRSE contains an IBUF. Check for such macros in the Libraries Guide and ensure that they are not being driven by an IBUF in your design.

If you design contains an IBUF with no loads, the above error is reported. Remove this IBUF to eliminate the error.
