Error (175005): Could not find a location with: RST_SRC_ID of <value>


When you implement multiple External Memory Interface IP cores in an Arria® 10 device and place them in the same I/O column, you may see the following fitter error if you feed the global_reset_n input of each interface with a different reset signal.

Error (16234): No legal location could be found out of 1 considered location(s).  Reasons why each location could not be used are summarized below:
Error (175005): Could not find a location with: RST_SRC_ID of <value> (1 location affected)

Unlike external memory controllers with UniPHY, all interfaces of the Arria 10 External Memory Interfaces in the same I/O column must share the same reset signal.


To avoid this fitter error, use same reset signal for all the memory controllers in the same I/O column.
