When generating 7 Series Integrated Block for PCI Express v1.4 core in Gen1 mode, the generated constraints file has a TIG constraint for 125 MHz clock as shown below:
NET "ext_clk.pipe_clock_i/clk_125mhz" TIG;
This is a known issue and will be fixed in a future release of the core. For Gen1 configuration, TIG should be removed.
