1.10.87. DUAL_PURPOSE_CLOCK_PIN_DELAY
Specifies the propagation delay from a dual-purpose clock pin to its fan-out destinations that are routed on the global clock network. Legal integer values range from 0 through 63 for Cyclone and Cyclone II device families and from 0 through 11 for Cyclone III, where 0 is the setting with the least delay and 63 is the setting with the most delay. This is an advanced option that should be used only after you have compiled a project, checked the I/O timing, and determined that the timing is unsatisfactory. For detailed information on how to use this option, refer to the data sheet for the device family. This option is ignored if it is applied to anything other than an input or bidirectional pin, or if the pin is user assigned to a non-dual-purpose clock pin location.
