[求助] xilinx: 普通IO能驱动MMCM吗?

h2o_freely

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
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),
, J3 R! C2 ~2 F/ O, k) jor b) the IOB is placed on a global clock capable IOB site which has a dedicated fast path to all MMCM sites.

ISE建议用 CLOCK_DEDICATED_ROUT = FALSE 来使error变为warning。

请教，这个如何解决？
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。
