Migrating UniPHY IP from 13.0 SP1 DP5 to 13.1 Resets GUI to Default Values - Migrating UniPHY IP from 13.0 SP1 DP5 to 13.1 Resets GUI to Default Values Description This problem affects DDR2, DDR3, LPDDR2, QDR II, RLDRAM II, and RLDRAM 3 UniPHY-based products. When a top-level EMIF wrapper generated in the Quartus II software version 13.0 SP1 DP5 is opened in version 13.1, the parameter editor GUI is reset to its default values and your design-specific parameters are lost. Resolution The workaround for this issue is to remove the ENABLE_DELAY_CHAIN_WRITE parameter from the top-level wrapper file. To do this, open the top-level wrapper file in an editor and remove the following line: -- Retrieval info: <generic name="ENABLE_DELAY_CHAIN_WRITE" value="false" /> � This issue will be fixed in a future release.
