Hi, Xiaoqiang


Warning (169064): Following 2 pins have no output enable or a GND or VCC output enable - later changes to this connectivity may change fitting results

Info (169065): Pin memory_mem_ck[0] has a permanently enabled output enable

Info (169065): Pin memory_mem_ck_n[0] has a permanently enabled output enable


Pin memory_mem_ck[0] and pin memory_mem_ck_n[0] are either have no output enable, or they are VCC and GND enable.

If you enable them later, it will change your fitting result. You may want to add an output enable that is not GND/VCC to them.


Thanks.


Eric
