Summary Copy Link Copied
This rule specifies the maximum and minimum hole size for pads and vias in the design. The hole size is the diameter of the hole to be drilled through the pad/via during fabrication.
Constraints Copy Link Copied
- Measurement Method - specifies the method used in defining the minimum/maximum hole sizes:
- Absolute - the values for minimum/maximum hole sizes will be absolute values.
- Percent - the minimum/maximum hole sizes will be expressed as percentages of the pad/via size.
- Minimum - the value for the minimum hole size with respect to pads and vias in the design. The value will appear as an absolute value (Default = 1mil) or percentage of the pad/via size (Default = 20%), depending on the measurement method selected.
- Maximum - the value for the maximum hole size with respect to pads and vias in the design. The value will appear as an absolute value (default = 100mil) or percentage of the pad/via size (Default = 80%), depending on the measurement method selected.
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.
