Spartan-6 Clocking Wizard - How to get access to the PLL Dynamic Reconfiguration Port (DRP)
When generating a PLL using the Clocking Wizard, it is not possible to get access to the Dynamic Reconfiguration (DRP) ports.How is a PLL generated to gain access tothe DRP?
The Clocking wizard generates a PLL_BASE primitive, which does not have the PLL DRP ports contained in it. The PLL_ADV primitive is required to get access to the DRP ports. To gain access to the PLL_ADV, use the codeprovided in the Spartan-6 PLL DRP application note, XAPP879: PLL Dynamic Reconfiguration.
