9.2i ISE - "WARNING:ProjectMgmt - "<top_module>.ngc" line 0 duplicate design unit: 'Module|<top_module>'"

Description

Keywords: synthesis

After I change the name of the top module in my Verilog code, the following warnings occur in the console. Occasionally, these warnings are repeated after the synthesis, NGDBuild, and MAP steps.

"WARNING:ProjectMgmt - "<top_module>.ngc" line 0
duplicate design unit: '<top_module>'
WARNING:ProjectMgmt - "<changed_top_module>.ngc" line 0
duplicate design unit: 'Module|<changed_top_module>'"

Solution

You can safely ignore these warnings.

This issue is scheduled to be fixed in ISE 10.1i.
