Version Found: MIG Virtex-6 and Spartan-6 v3.92 Version Resolved: Not Resolved
When generating a MIG Virtex-6 v3.92 DDR3 design targeting the SODIMM MT4JSF12864HZ-1G4, the following timing parameters do not match those defined in the memory vendor data sheet for 800/1066Mbps speeds:
tRRD = 7500
These incorrect parameter values can potentially cause failures in your memory application and should be fixed.
In order to resolve this issue, a custom memory part can be created and the timing parameters updated to accurately reflect the values defined in the memory vendors data sheet.
