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