Critical Issue
Description
The memory presets contain incorrect data for the tDSa and tDHa memory
timing parameters.
This issue affects all configurations.
Timing analysis results for write and address/command paths may be incorrect.
Resolution
Make sure that the memory timing parameters in the MegaWizard Plug-In Manager match the datasheet of the target memory device. The output edge rate and the use of single-ended versus differential DQS may affect certain memory parameters.
This issue will be fixed in a future version of the DDR2 SDRAM Controller with ALTMEMPHY IP.
