When I attempt to generate a core under the current project settings, two unexpected warnings (Sim:541 and Sim:560) occur. For example, when I attempt to generate or regenerate a core in project"C:\designs\project\," the following warning messages are displayed,even though the core I am attempting to generate is not named "my_core":
"Started : "Regenerate Core".

All runtime messages will be recorded in 'C:\designs\project\ipcore_dir\ipcore_dir\coregen.log
WARNING:sim:541 - Could not import file 'C:\designs\project\ipcore_dir\my_core.xco' during project migration. A component instance with name 'my_core' already exists within the project. Please check other XCO/XCP files in the same directory to resolve any identical 'component_name' values.
WARNING:sim:560 - Failed to create component instance for XCO file 'C:\designs\project\ipcore_dir\my_core.xco' during projectmigration
The error messages only occur if there are two XCO files in the project directory with the same component name (my_core in the example above). However, the messageshould only be displayed whengenerating or regenerating a core with the name conflict.
To remove the warning, examine the ".xco" and ".xcp" files in the CORE Generator project directory, and remove or rename the cores with the conflicting names.
