PLL/DLL Run-time Reconfiguration
The PLLs and DLLs in the HardCopy design have run-time reconfiguration enabled—
provided that they are not in PLL/DLL slave mode.
When the PLLs and DLLs are generated with reconfiguration enabled, there are extra
signals that must be connected and driven by user logic. In the example design
generated during IP core generation, the PLL/DLL reconfiguration signals are
brought to the top level and connected to constants, as shown in
For information about PLL megafunctions and reconfiguration, refer to the
