Advanced Rule Set

• Enables easy definition of advanced rules, including rules for impedance matching (layer-controlled routing and width requirements)
• Allows hierarchical rules definition (class, pin-pair, group, and conditional)
• Defines component pin clearance and routing rules for interactive or batch-mode use
• Defines rules for min/max, matched-length, and differential pairs
• Checks all constraints during online and batch DRC

NOTE: The Advanced Rule Set (ARS) is required for PADS Router HSD and PADS AutoRouter HSD. This option replaces the EDC and ERS options supported by earlier versions of PADS Layout.
