Are there any differences in behavior between RTL simulation and hardware when implementing Rx CDR PLL dynamic reconfiguration using the direct write method of Stratix® V devices?

Description

Yes, you may see differences in behavior between RTL simulation and hardware when implementing Rx CDR PLL dynamic reconfiguration using the direct write method in Stratix® V devices.

Resolution

For RTL simulation, you may write the difference in the MIF file using the direct write method. For hardware, the entire Rx CDR PLL MIF file must be written.
