How should I place the QDR II/QDR II+ mem_cq and mem_cq_n pins in Arria® V GX/GT/ST/SX devices?

Description

From the device pinout file, there is only one pin location available for both mem_cq and mem_cq_n pins.

Resolution

For these Arria® V devices, complementary strobes are not supported so only one of the mem_cq or mem_cq_n pins will be used depending on the read latency setting.
