maxClusterDistance

Specifies that pins on multi-pin nets that are less than this distance from each other will be considered as one cluster for strand routing. If not specified, 10 * via-to-via pitch (the maximum value from all valid routing layers) is used. Strand routing can only route two clusters per net. Nets with greater than two clusters will not be routed.

maxClusterDistance Quick Reference

Value Type

maxClusterDistance constraints have a Value for the maximum distance between pins, in user units, for pins to be clustered together.

Examples

In this example, pins that are less than or equal to 0.4 μm from another pin on the net will be considered as part of the same cluster for strand routing on the Metal1 layer.
