FLP-40002: Very Small Routing Regions
Description
Very small routing regions fragment the floorplan and may not be able to fit the required logic.
This condition may lead to sub-optimal placement and routing of the design as well as an increased compilation runtime. The region must span (in horizontal and vertical directions) at least the number of units specified in the min_dimension parameter. For regions comprising more than one rectangle, the bounding box is measured.
Parameter
| Name | Default Value | Description |
|---|---|---|
| min_dimension | 4 |
Reports a violation for Logic Lock regions that have a dimension smaller than the value specified in this parameter. |
Recommendation
Ensure that the region size is large enough to contain the required logic, or consider switching to location assignments if constraining a very targeted and smaller amount of logic.
