这个顶一下，我现在也遇到这样的问题，希望楼主不吝赐教！

看下Console里面Errors详细解释，应该会指出某个管脚分配的问题

楼主是不是将差分时钟输入到DCM，同时又将此差分时钟驱动其余器件，如DDR等？

楼主你好，我最近也出现过这种问题，就是在使用aurora核的时候。报错如下：希望帮忙解决一下
Pack:1107 - Pack was unable to combine the symbols listed below into a
   single IOB component because the site type selected is not compatible.

   Further explanation:
   The component type is determined by the types of logic and the properties and
   configuration of the logic it contains. In this case an IO component of type
   IOB was chosen because the IO contains symbols and/or properties consistent
   with input, output, or bi-directional usage and contains no other symbols or
   properties that require a more specific IO component type. Please double
   check that the types of logic elements and all of their relevant properties
   and configuration options are compatible with the physical site type of the
   constraint.

   Summary:
   Symbols involved:
   
PAD symbol "GTPD0_P" (Pad Signal = GTPD0_P)
   
DIFFAMP symbol "IBUFDS/IBUFDS" (Output Signal = GTPD0_left_i)
   Component type involved: IOB
   Site Location involved: A10
   Site Type involved: IPAD


Mapping completed.
See MAP report file "aurora_8b10b_v5_3_example_design_map.mrp" for details.
Problem encountered during the packing phase.
