AC701 board critical warning MIG IP block vivado 2018.3

Hi, I have this critical warning in my design

[Netlist 29-160] Cannot set property 'IOSTANDARD', because the property does not exist for objects of type 'pin'. ["c:/Vivado_2018/HDMI_AC_V6/HDMI_AC_V5/HDMI_AC_V2.srcs/sources_1/bd/design_HDMI/ip/design_HDMI_mig_7series_0_0/design_HDMI_mig_7series_0_0/user_design/constraints/design_HDMI_mig_7series_0_0.xdc":580]

[Netlist 29-160] Cannot set property 'PACKAGE_PIN', because the property does not exist for objects of type 'pin'. ["c:/Vivado_2018/HDMI_AC_V6/HDMI_AC_V5/HDMI_AC_V2.srcs/sources_1/bd/design_HDMI/ip/design_HDMI_mig_7series_0_0/design_HDMI_mig_7series_0_0/user_design/constraints/design_HDMI_mig_7series_0_0.xdc":581]

# PadFunction: IO_L12P_T1_MRCC_34 
set_property IOSTANDARD SSTL15 [get_ports {sys_clk_i}]
set_property PACKAGE_PIN N3 [get_ports {sys_clk_i}]

does anybody knows what causes this issue and how to resolve it?

thanks

Hi @jg_spitfire 

 

When I look at the IPI canvas you shared the sys_clk_i is an output from an MMCM, so you cannot set the pin/iostandard because its an internally generated signal.

Could it be the sys_diff_clk you need to set theIOSTANDARD on?
