Stratix V QDR II and QDR II+ SRAM Controller with UniPHY and RLDRAM II Controller with UniPHY Memory Interfaces May Exhibit Write Timing Failure

Description

Memory interfaces targeting Stratix V devices may exhibit write setup or write hold timing failures.

Workaround/Fix

A workaround for interfaces running at 400MHz or slower is to enable the high-performance Nios II-based sequencer instead of the RTL-based sequencer.
