IP Product: Renewal QDRII / II+ Controller with UniPHY

Why is my Arria V QDR II and QDRII+ SRAM controller with UniPHY IP missing a CQn clock signal ?

Description

The Arria® V architecture does not support a complementary CQ clock. Instead, both edges of the CQ clock are used to capture the read data.
