14.4 - XPS - XADC Instantiation option is grayed out in the config IP GUI for AXI 7 Series DDRx IP

Description

The Design Advisory for MIG 7 Series DDR3/DDR2 (Xilinx Answer 51687) states, "To disable the instantiation of the XADC within the generated MIG 7 series core, set the "XADC Instantiation" option to "Disabled." This option is available on the "FPGA Options" screen of the MIG 7 Series tool"

However, the XADC Instantiation option is grayed out in the configuration IP GUI for AXI 7 series DDRx IP, and cannot be changed.

How can I fix this?

Solution

The parameter C_USE_EXTERNAL_XADC can be set manually to 1 in the MHS file in the XPS project as shown below:
