CLB Switching Characteristics
Delays originating at F/G inputs vary slightly according to the input used (see
listed below are worst-case. Precise values are provided by the timing analyzer.

A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
if a “0” is listed, there is no positive hold time.
