Weakly-Connected Instance Pins During Extraction
The extractor also considers the external loops of current that can exist in the connections made to weakly-connected instance pins. This means it is legal to route two weakly-connected instance pin figures, provided the connections on these pins are routed together. If this is the case, the extractor does not detect a violation because it is assumed that the current will not flow through the resistive path between the two pin figures inside the instance.
When the extractor detects an illegal weak-connect violation, the generated marker is a line marker drawn between the two instance pin figures that are overlapped by unconnected top-level shapes on the same net. This provides better visibility of the problem and eases the process of fixing it. The Annotation Browser highlights both the line marker and the two instance pin figures.
Any incremental updates that you make are also considered for the detection of illegal weak-connect violations.
