Quartus

Can't place carry or cascade chain starting with cell <name>


CAUSE: The Fitter could not place the specified chain in any legal position on the device. This error can be caused by location assignments on cells in the chain that conflict with each other or other cells in the design. This error may also be caused by too many control or clock signals in the chain.
ACTION: Check the location assignments on cells in the chain, and location assignments of other cells in the same LAB or Row as the chain which may cause the chain to not be placed legally. In addition, check that the chain does not have too many control or clock signals which may cause the chain to not be placed legally.
