ID:19696 In MACRO "<string>", node "<string>" has invalid <string> value <int> that violates carry chain placement constraints

CAUSE: The node belongs to a carry chain, but its X offset, Y offset, or Z value violates the carry chain placement constraint.

ACTION: Correct the X offset, Y offset, or Z value of the node according to carry chain placement constraints in the QSF. A carry chain needs to be placed in a continuous vertical ordered fashion with the carry chain head being at the top of the chain.
