CAUSE: The specified clock is derived from one or more generated clocks, and the product of the multiply_by/divide_by options of the specified clock and its ancestors results in a value larger than the maximum allowed.

ACTION: When defining mutiply_by or divide_by factors for clocks, make sure that the accumulated value is lower than the maximum allowed (999999999).
