Rule category: Electrical
Rule classification: Unary
This rule tests the completion status of each net that falls under the scope (full query) of the rule. If a net is incomplete then each completed section (sub-net) is listed along with the routing completion. The routing completion is defined as:
(connections complete / total number of connections) x 100
The PCB Editor's Design Rule Checking system typically sees a net as being routed if all nodes in that net (component pads) are connected through the use of net-aware design objects (tracks, arcs, pads, vias, and polygons). These objects are considered connected if they touch each other. However, while simply touching makes a perceived connection to the software, when it comes time to fabricate the board, the fragility of some of these 'connections' can cause critical issues, especially where the objects - for example two contiguous track segments, or a track entering a pad/via - are only slightly touching. Such connections are often referred to as 'Bad Connections', 'Poor Connections', or 'Incomplete Connections'. This rule can also be configured to test for such poor connections.
Check for incomplete connections - with this option enabled, the following additional checks on connectivity between applicable design objects are made:
All rules are resolved by the priority setting. The system goes through the rules from highest to lowest priority and picks the first one whose scope expression matches the object(s) being checked.
