Timing Closure for Soft LPDDR2 Interfaces May Not be Robust


This problem affects LPDDR2 products.

Soft LPDDR2 interfaces targeting Arria V or Cyclone V devices may have difficulty achieving timing closure.


The workaround for this issue is to turn on physical synthesis with high effort, or try a different fitter seed.

This issue will be fixed in a future release.
