MIG 7 Series - Timing parameter values are incorrect for certain memory parts


Version Found: MIG 7 Series v2.3
Version Resolved: See (Xilinx Answer 54025)

When generating MIG 7 series targeting SODIMM MT4JSF12864HZ-1G4, the following timing parameters do not match those defined in the memory vendor data sheet for 800MT/s designs and 1066MT/s designs:

  •  tRRD
  •  tRAS


These incorrect parameter values can cause failures in memory design and should be fixed.  

In order to resolve this issue, create a custom memory part and update the timing parameters to accurately reflect the values defined in the memory vendors data sheet.
