UltraScale DDR4 - Unable to set data width to 80 for a x16 Wide Interface Component in custom CSV


Version Found: DDR4 v2.2

Version Resolved: See (Xilinx Answer 69035)

When using a x16 Wide custom part (that has a component width of 8) the following error is seen when data width is set to 80:

[Mig 66-120] Custom Part (MYDDR4) with parameter: Data widths having value: 8,16,24,32,40,48,56,64,72,80 is invalid.
The valid values for Data widths are 8, 16, 24, 32, 40, 48, 56, 64 and 72 when Part type is Components and Memory component width is 8.


There is currently no work-around for this issue.

We do support the MT40A1G16WBU-083E natively which can utilize a data width of 80 bits.
