Rule category: Routing

Rule classification: Unary

Summary Copy Link Copied

This rule assigns a routing priority to the net(s) targeted by the rule. The Autorouter uses the assigned priority value to gauge the routing importance of each net in the design and hence determine which nets should be routed first.

All design rules are created and managed within the PCB Rules and Constraints Editor dialog. For a high-level view of working with the design rules system, see Defining, Scoping & Managing PCB Design Rules.

Constraints Copy Link Copied

Default constraint for the Routing Priority rule.

Routing Priority - the priority value assigned to the net(s) targeted by the scope (full query) of the rule. Enter a value between 0 and 100, whereby the higher the number assigned, the greater the priority when routing.

How Duplicate Rule Contentions are Resolved Copy Link Copied

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.

Rule Application Copy Link Copied

During autorouting.
