Im gettin the following during my cts. Can anyone explain what the error and how to get over it? Im using 8.1 Encounter. Any help is greatly appreciated..

CTS cannot proceed. Please check the clock spec files and re-start CTS again
I just had something similar happen in my design.
You have two converging clocks, which in itself is not a problem, but one of the clocks has an exclude pin and the other does not. Look in your clock spec file at the two clocks mentioned. Find the one that has the ExcludePin setting and copy that to the definition for the other clock. Then rerun CTS.
