Rule category: Routing
Rule classification: Unary
Summary
This rule specifies the corner style to be used during autorouting.
Constraints
- Style - specifies which routing corner style to use. The following three styles are available:
90 Degrees
.45 Degrees
.Rounded
.
- Setback - these two fields allow you to define a minimum and maximum value for the setback, when using the
45 Degrees
andRounded
corner styles. The setback is the distance from the 'true' corner location (that which would exist if using the90 Degrees
style) to the point at which the Autorouter should begin its chamfering or rounding, in effect controlling miter size or corner radius.
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
This rule is intended for use by third party Autorouters that implement 45° routing as a post process. It is not followed by the Situs Autorouter, which implements 45° routing as a native process.
