FLP-40003: Narrow Region
Description
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.
Parameter
| Name | Default Value | Description |
|---|---|---|
| Region_Aspect_Ratio | 0.6 |
Reports a violation for Logic Lock regions that have aspect ratio lower than specified in this parameter. It accepts values in the range of 0.0 to 1.0. |
Recommendation
Ensure that Logic Lock regions are within the aspect ratio threshold, and are not causing congestion around its edges or corners.
