|
* Routing and Placement Rule Hierarchies
|
|
*
|
|
* Routing and placement rules can be defined at multiple levels of design
|
|
* specification. When a routing or placement rule is defined for an object at
|
|
* multiple levels, a predefined routing or placement precedence order
|
|
* automatically determines which rule to apply to the object. The routing rule
|
|
* precedence order is
|
|
*
|
|
* pcb < layer < class < class layer < group_set < group_set layer < net <
|
|
* net layer < group < group layer < fromto < fromto layer < class_class <
|
|
* class_class layer < padstack < region < class region < net region <
|
|
* class_class region
|
|
*
|
|
* A pcb rule (global rule for the PCB design) has the lowest precedence in the
|
|
* hierarchy. A class-to-class region rule has the highest precedence. Rules
|
|
* set at one level of the hierarchy override conflicting rules set at lower
|
|
* levels. The placement rule precedence order is
|
|
*
|
|
* pcb < image_set < image < component < super cluster < room <
|
|
* room_image_set < family_family < image_image
|
|
*
|
|
* A pcb rule (global rule for the PCB design) has the lowest precedence in the
|
|
* hierarchy. An image-to-image rule has the highest precedence. Rules set at
|
|
