CAUSE: The carry chain that starts with the specified CARRY primitive requires more clear signals than the device can contain. As a result, the Quartus Prime software cannot place the carry chain.
ACTION: Modify the design by breaking the chain into smaller chains that require fewer clear signals or by reducing the number of clear signals required by the specified carry chain. You can also change the maximum length of the carry chain with the Carry Chain Length option.
