12.1 ncelab - "*W,SDFINF: Instance XIL_ML_UNUSED_DCM_1/CLKFB not found at scope level , line ."

Description

When I run timing simulation in NCsim, the following warning occurs:

"*W,SDFINF: Instance XIL_ML_UNUSED_DCM_1/CLKFB not found at scope level < top-level > < sdf name > , line < number >."

How can I resolve this issue?

Solution

This issue has been fixed and is scheduled to be available in IUS9.2 S17 release.

If this warning occurs on the auto-generated DCM, then it can be safely ignored. For all other components use the -ne switch.
