If after reducing a library, you notice that your resulting image is too slim, you can
            manually remove the reduced library from the Reductions directory,
            and then rebuild your image using a standard, full-weight shared library. 
            
            
         
         
         
         To restore a library to its original state: 
         
         
         
            - In the System Builder Projects view, open the
                  Reductions directory in your project. This directory
                  contains the reduced versions of your libraries. 
- Right-click the library you want to remove and select Delete.
                  Click OK to confirm your selection. The IDE deletes the
                  unwanted library; when you rebuild your project, the IDE uses the original version
                  of the library.
