Bank 5A can't be assigned to 1.8V level - Bank 5A can't be assigned to 1.8V level Dear Sir/Madam, Quartus:16.1 FPGA :5CGXFC3B7F23C8N DDR3:MT41k5|2M16 Q: DDR3 is assigned to bank 7A/8A(1.35V), But I can't assign 1.8V or 3.3V to bank 5A except 1.35V , Could you help me the pin assignment is attached.

Is it a SSTL135 IO that does not has location assignment and auto assign to bank 5A?

With only the QSF I am unable to check those pin that not assigned, so Quartus will auto assign it and maybe will assign it into bank 5A and cause the conflict. So, please attach QAR file for me to check, or check is there any IO with IO standard SSTL135 that do not have user location assignment in QSF.
