Rule category: Routing
Rule classification: Unary
Summary
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.
Constraints
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
0and100, whereby the higher the number assigned, the greater the priority when routing.
How Duplicate Rule Contentions are Resolved
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
During autorouting.
