4.2i XABEL, Foundation - The following message appears during synthesis: "ref_2_inst: dangling port"

Description

Keywords: XABEL, macro, PCM, Project Manager

Urgency: Standard

General Description:
When I synthesize an ABEL module in Foundation, a series of the following warnings appears in the Project Manager message log window during synthesis:

"ref_2_inst: dangling port"

Solution

These messages may be safely ignored.

Generally, one of these messages will be reported for each port in the ABEL module. As the ABEL file was compiled as a macro and not as a chip, these ports are reported as dangling, which results in the warnings.
