extractStopLevel

layout extractStopLevel int { 0 | 1 | 2 | ... | 32 }

Description

Specifies how much of the design hierarchy the extractor considers when extracting the design. The default is 0, which means that the extractor extracts only:

• Top-level objects. Shapes, vias, and instances are used to implement pins.
• Instance pins of top-level instances. These instance pins represent the interface of top-level instances to the lower levels in the design and are themselves considered to be at the top level.

Increasing the extractStopLevel increases the visibility of the extractor to shapes inside the hierarchy. For example:

extractStopLevel	Means...
1	extractStopLevel 0 + objects at level 1 + instance pins at level 2
2	extractStopLevel 1 + objects at level 2 + instance pins at level 3

Whatever the extractStopLevel, the extractor only extracts the top level - it only changes the connectivity of objects or creates markers at the top level.
