CAUSE: You assigned nodes of a DSP block slice to a location that does not contain any DSP blocks. The locations for each of the nodes in the slice do not overlap, or together constrain the entire slice to a location that does not include DSP blocks. Click the + icon to expand this message in the Messages window or Messages section of the Report window to display details about why the Quartus Prime software could not place the nodes.
ACTION: Assign the nodes in the slice to a different location so that the slice's resulting location contains some DSP blocks. If the nodes 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 DSP from being assigned to the region).
