FLP-40003: Narrow Region


Highly skewed region shapes (long or wide) may lead to a very fragmented placement region that may cause long detours around the region, ultimately causing congestion and timing failures.

Note: Aspect ratio is calculated as a ratio of smaller dimension to larger dimension of region bounding box.


Name Description Type Default Value Min Value Max Value
region_aspect_ratio A violation is reported for logic lock regions that have aspect ratio lower than specified in this parameter. double 0.6 1.0 0.0


Ensure that Logic Lock regions are within the aspect ratio threshold, and are not causing congestion around its edges or corners.




Tag Description
region-constraints Design rule checks related to region constraints in the design (both placement and routing).
