ID:165021 The "<name>" I/O standard and/or the "<name>" current strength on the pin "<name>" is not supported for DDR/DDR2 external memory interfaces

CAUSE: The I/O standard and/or the current strength on the DQS pin used with the double data rate (DDR) controller is not supported. If you have not made any I/O assignments to the pin, then the default I/O assignments for the project are not supported.

ACTION: Modify the project by adding a supported I/O standard and current strength on all pins used with the DDR controller. The supported list of I/O standards appears in a sub-message.
