使用PLB总线没问题，但是使用AXI的有问题，相同的设置，出错的部分在BMM文件。
使用PLB和AXI，edk都会生成一个 ***.BMM 文件，ise根据这个BMM文件重新生成一个 ***_bd.BMM文件用于生成bit文件。
PLB的 ***_bd.BMM内容如下：
///////////////////////////////////////////////////////////////////////////////

两者的差别就在与 PLB的share_bram_block_combined 已经有 PLACED = ****; 而AXI的axi_bram_ctrl_0_bram_block_combined 这部分后面什么都没有，好像palace出问题了，各位有没有遇到相似的问题，可有解决办法？ |
