NGDBUILD M1.5: ERROR: based: 6 - On or above line in file ...


Occasionally, NGDBUILD will give the error: 


ERROR: based: 6 - On or above line <line> in file <file>:  

Duplicate entry for component <component> in library work.


This has been seen to happen when there is a user-created macro that has been named the same as a standard Xilinx library  

component. This is especially likely if the user is generating Logiblox or CoreGen modules. The solution is to regenerate the Logiblox or CoreGen module with a name different from those of the library components.
