Utility Buffer can't change the value of IBUF_DS_ODIV2 and BUFG_GT_O pins

Hi,

I'm using the utility buffer to provide a clock to Vid_phy_controller while running a synthesis, it fails to set clock pin values. expected value to be set 1. But utility buffer show warning, the value is read-only and the default value is set 0. 

Kindly let me know how fix it.

Platform: ZCU104

Vivado 2019.1 version is used.

Following is the error log:

Hi @madan_1993 

I do not understand why you cascade the 2 utility buffers. This is your issue because the is no path inside the FPGA for this. You need a single utility buffer
