7 Series FPGAs - What are the Addresses and Values for Dynamic Reconfiguration of the MMCM/PLL through the DRP?

Description

The DRP functionality for the 7 Series FPGA MMCM and PLL is supported through an Application Note and associated reference design.

Solution

XAPP888 MMCM and PLL Dynamic Reconfiguration, (https://www.xilinx.com/support/documentation/application_notes/xapp888_7Series_DynamicRecon.pdf), describes the DRP feature in detail.

A HDL reference design is provided along with the Application Note. The reference design uses a state machine to drive the DRP and ensures the registers are controlled in the correct sequence.

The register map is build into the _drp_func.h in the XAPP888 but will not be provided to customers outside of the XAPP implementation.
