[Vivado 12-1411] Cannot set LOC property of ports, clk_125mhz_ibufg_inst_1 Illegal to place instance clk_125mhz_ibufg_inst_1 on site C8. The location site type (IPAD) and bel type (BUFFER) do not match the cell type (IBUFDS). Instance clk_125mhz_ibufg_inst_1 belongs to a shape with reference instance clk_125mhz_ibufg_inst_1. Shape elements have relative placement respect to each other. The invalid location might results from a constraint on any of the instance in the shape.

检查我的引脚,我是按照原理图约束的,原理图请见(图1).但是vivado的I/OPorts里面好像并没有这个引脚,导致我的差分时钟(serdes_refclk_p)一直无法绑定,请见(图2)(图中根本就没有支持C8这个引脚)。关于差分时钟的的约束文件如下:
