Error (12002): Port "strobe_n_io" does not exist in macrofunction "dq_ddio.ubidir_dq_dqs"


You may see the above error message when compiling a DDR2 hard memory controller with the DQS# Enable option under the Memory Parameters tab not selected.


To work around this error, open the <variation_name>_p0_acv_hard_io_pads.v file and comment out the following line:

//.strobe_n_io (mem_dqs_n[i])

This problem will be fixed in a future version of the Quartus® II software.
