MMCME2_ADV Unisim Model is not asserting LOCKED when Simulating with NCSIM

Description

The MMCME2_ADV Unisim Model is not asserting LOCKED when Simulating with NCSIM.

Solution

This is a known issue with the MMCME2_ADV Model.


The effect of this issue was observed while simulating a MIG 7 Series (v1.5) example design in Cadence NCSIM 11.1.

Due to the unavailability of the LOCK signal from one of the infrastructure MMCM (mmcm_i), the design was not being calibrated. 


This issue has been resolved in the 14.2 release with an updated model.
