我在用Spartan6内嵌的硬核MPMC去控制DDR2 内存,在MIG里产生了memory Interface,然后自己写顶层模块,调用MIG产生的控制模块,综合可以通过,但是Map过不了,报错如下:ERROR:Place:1333 - Following IOB's that have input/output programming are locked
to the bank 1 that does not support such values
IO Standard: Name = LVDS_25, VREF = NR, VCCO = 2.50, TERM = NONE, DIR =
BIDIR, DRIVE_STR = NR
List of locked IOB's:
mcb1_dram_dqs
mcb1_dram_udqs
mcb1_dram_dqs_n
mcb1_dram_udqs_n
ERROR:Pack:1654 - The timing-driven placement phase encountered an error.
UCF文件是MIG自动产生的啊~~而且我的开发板上的DDR2内存一条在Bank1,一条在Bank5.请问如何解决啊?谢谢~~ |
