OPTIMIZE_HOLD_TIMING

Allows the Fitter to optimize hold time by adding delay to the appropriate paths. The Optimize Timing option must be turned on in order for this option to work. If you are using the Timing Analyzer, and specify the I/O paths and Minimum tpd Paths setting, all assignments involving I/O pins are optimized. Specifying the All Paths setting directs the Fitter to optimize the hold time of all paths. Turning off this option directs the Fitter not to optimize the hold time of any paths.
