zcu106 10G ethernet subsystem critical warning

[andrea@ross]

Hi,

I'm trying to use the 10G ethernet subsystem, but I have a critical warning during the implementation:

CRITICAL WARNING: [Vivado 12-1411] Cannot set LOC property of ports, Could not find a valid bel for the shape with the following elements: 
design_1_i/design_1_i/xxv_ethernet_0/inst/IBUFDS_GTE4_GTREFCLK0_INST
user_si570_sysclk_clk_n
user_si570_sysclk_clk_p
 CRITICAL WARNING: [Vivado 12-1411] Cannot set LOC property of ports, Could not find a valid bel for the shape with the following elements: 
design_1_i/design_1_i/xxv_ethernet_0/inst/IBUFDS_GTE4_GTREFCLK0_INST
user_si570_sysclk_clk_n
user_si570_sysclk_clk_p

I don't know how to solve it.

Hey andrea@ross,

What constraints have you applied to those ports, is there anything in your constraints file? And which part are you targetting? You might try checking or replacing the pins.

Did you start with the IP Example Design?
