General Description: When using a coregen module in an hdl project in ISE the following information window pops up:
The source '...' in the file '...' conflicts with the source '...' in the file '...'.
The definition must be resolved before processes will be available for the source.
As of 3.1i sp6, coregen modules are incorporated differently. Now, the .xco file gets placed directly into the sources lists. This means a module declaration for the coregen component is not necessary. Having one conflicts with the already declared component in the xco file. Remove the module declaration and the the warning will go away.
