ID:176454 Can't merge Clock Control Blocks <name> (clock type <name>) and <name> (clock type <name>) -- different clock types

CAUSE: The Fitter attempted to merge the two specified Clock Control Blocks. However, the Clock Control Blocks use different clock types. For Clock Control Blocks to be merged by the Fitter, they both must use the same clock type. This message can occur when the Fitter attempts to merge two Clock Control Blocks because they are described by logic in the design that needs to be implemented in a single Clock Control Block.

ACTION: Modify the design so that the Clock Control Blocks use the same clock type.
