ID:18866 Clock <name> is constrained by a Clock Region assignment to coordinates <given_xy_bottom_left> and <given_xy_top_right>, which are not aligned to clock sector boundaries. The Fitter is expanding the constraint to the closest enclosing sector boundaries: <new_bottom_left> and <new_top_right>

CAUSE: The clock has been defined to be in a region that does not line up with sector boundaries.

ACTION: Modify the coordinates to ensure that the region aligns properly. Clocks can be constrained using sector coordinates (in the form "SX# SY# SX# SY#") which will automatically ensure alignment with sector boudaries.
