ID:20340 The product of the -multiply_by/-divide_by options for generated clock '<Clock Name>' and its ancestors results in a value larger than the maximum allowed. This clock will be ignored.

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 the -multiply_by or -divide_by factors for clocks, make sure that the accumulated value is lower than the maximum allowed (999999999).
