vivado自定义带axi接口的ip核地址映射出现错误

无碍

各位大佬，我自己写了一个带axi接口的计数器count的ip核，加进了原来的工程里面，但是好像地址映射还是偏移量报错了，有critical warning.



报错情况具体如下：

[BD 41-1649] </count_ip_0/S0_AXI/S0_AXI_reg> is mapped at contiguous segments in master </processing_system7_0/Data/SEG_count_ip_0_S0_AXI_reg2> at <0x80000000 [ 32K ]> and in master </processing_system7_0/Data/SEG_count_ip_0_S0_AXI_reg> at <0x7FFF8000 [ 32K ]>. It is illegal to have the same peripheral mapped to different addresses within the same network. Peripherals must be mapped to the same offset in all masters, or to contiguous addresses that can be combined into a single aligned address. The combination of these two addresses is <0x7FFF8000 [ 64K ]> which is misaligned.
这个警告的意思是我的count的ip核的<S0_AXI_reg>映射到了主机master<processing_system7_0>的连续段，将同一外围设备映射到同一网络中的不同地址是非法的。
外围设备必须映射到所有主设备中的相同偏移量，或者映射到可以合并为单个对齐地址的连续地址。这两个地址的组合为<0x7FFF8000[64K]>，未对齐。


[BD 41-1267] </count_ip_0/S0_AXI/S0_AXI_reg> is mapped into related masters </processing_system7_0/Data> and </processing_system7_0/Data> at different offsets <0x80000000 [ 32K ]> and <0x7FFF8000 [ 32K ]>
这个警告是说我的count的ip核的<S0_AXI_reg>映射到了主机master<processing_system7_0>的不同的偏移量。


想请问一下各位大佬，这个地址映射和偏移量这两个问题，要怎么解决？如果要将两个地址映射合并成一个地址的话，要怎么操作？


谢谢大家！！！

如果是要修改映射地址的话，可以在block design中由diagram界面中切换至“Address Editor”页面，展开“ processing_system7_0”下的“ Data”，然后对不同的外设的基地址和范围进行修改
