Hi all,

I have the same problem with "DDR2 SDRAM High Performance Controller II" on the Startix IV EP4SE230F29.

My specific error is:

Error: Can't place DQ I/O "mem_dq_to_and_from_the_ddr2_controller_high_perf[5]" to I/O location Pin_AB25 because its memory interface I/O group cannot be placed

Error: Can't place stratixiv_io_pad "mem_dq_to_and_from_the_ddr2_controller_high_perf[5]" to location "PIN AB25".

Does anybody know how to solve this problem?

Thanks

Luca
