Low Frequency Limit for DDR2 and LPDDR2 on Arria V and Cyclone V Devices

Description

This problem affects DDR2 and LPDDR2 products.

For Arria V devices, DDR2 and LPDDR2 interfaces at frequencies less than 200 MHz will not operate correctly.

For Cyclone V devices, DDR2 and LPDDR2 interfaces at frequencies less than 167 MHz will not operate correctly.

Workaround/Fix

The workaround for this issue is to not use frequencies less than 200 MHz for Arria V devices, or 167 MHz for Cyclone V devices.

This issue will not be fixed.
