I haven't actually checked, but according to CEDET manual (http://www.randomsample.de/cedetdocs/common/cedet/CScope.html):

semantic can use CScope as a back end for database searches. To enable it, use:

 (semanticdb-enable-cscope-databases)

This will enable the use of cscope for all C and C++ buffers.

CScope will then be used for project-wide searches as a backup when pre-existing semantic database searches may not have parsed all your files.
