map的时候总是报错 ：ERROR : Place : 1155 - A clock IOB/MMCM clock component pair have been found MMCM site pair. The clock IOB component <xx>is placed at site <M22>. the corresponding MMCM component <XXX> is placed at site <MMCM_ADV_X0Y7>.The clock IO can use the fast path between the IOB and the clock manager if u$ ^, I% c H& ^8 ^
a) the IOB is placed on a local clock capable IOB site in the same horizontal clock region pair as the MMCM site (fastest dedicated path),

请问，是否还有别的方法？

请教，这个如何解决？
1 T1 o; L, i& O' e因为pcb已经做好，pin的位置都固定了，没法把时钟信号重新连dao clock capable IOB的pin上了。
