ACTION: Select a larger device or make sure that no interaction problems occur between RAM cells due to assignments made to the design. Also make sure that all RAM cells are assigned the correct address and control signals. If the RAM cells are assigned to a LogicLock region, one or more of the following actions may resolve the problem:
- Adjust the size and/or origin of the region to make sure that it covers enough resource blocks for its members. In addition, make sure that the required resource blocks are not also covered by another LogicLock region with the Reserved property set to On or Limited.
- Consider setting the region size and origin to Auto and Floating, respectively. This allows the Fitter to automatically determine a feasible region placement.
- Reduce the region's resource requirement, by eliminating some or all of its members requiring the specified resource type. You may also fine-tune existing region memberships by specifying a list of Excluded Element Types for each LogicLock membership assignment (e.g. to exclude all design elements of type RAM from being assigned to the region).
