是不是说明时钟不能使用呢
ERRORlace:962 - A DCM / BUFGCTRL clock component pair have been found that are not placed at an optimal DCM / BUFGCTRL
   site pair. The DCM component <u1/U7/p2/DCM_SP_INST> is locked to site <DCM_X2Y0> and the corresponding BUFGCTRL
   component <u1/U7/p2/CLK180_BUFG_INST> is locked to site <BUFGMUX_X2Y10>.
这个X和Y是什么意思呢

PIN "u1/U7/p1/DCM_SP_INST.CLKFX" CLOCK_DEDICATED_ROUTE = FALSE;
  PIN "u1/U7/p2/DCM_SP_INST.CLK180" CLOCK_DEDICATED_ROUTE = FALSE;
这是不是说明CLKFX和CLK180没有用到呢
