ID:19874 External memory and PHYLite interfaces have only one debug toolkit when constrained to the same I/O column. The following IO_AUX/IOSSMs were constrained to the same column, and have a debug interface connected:

CAUSE: Each EMIF/PHYLite system with the debug interface port exposed and connected to unique logic must be placed in its own I/O column. When more than one IO_AUX or IOSSM is found with the debug interface connected, this error occurs.

ACTION: Only one EMIF/PHYLite debug interface should be instantiated per I/O column. If multiple EMIF/PHYLite IP cores exists per I/O column that must share the debug interface and logic, these IP cores must be daisy-chained together. Consult the EMIF/PHYLite documentation for details. If you no longer need to use the EMIF/PHYLite debug interface, you can resolve the error by regenerating the EMIF/PHYLite IP core with the debug interface disabled, and recompiling the design.
