Many rule types have default rules created when a new PCB document is created. The rule name will appear bold to distinguish it as being new and yet to be 'applied'. The new rule will be added to the folder-tree and will also appear in the summary list for that rule type. New Rule - use this command to create a new rule of the currently selected rule type.The following commands are available from the right-clickВ menu for the left-hand pane: Д¬lick on the root folder to access a summary listing in the main editing region of the dialog of all specific rules that have been definedВ for all design rule typesВ across all categories.Д¬lick on a category folder to access a summary listing of all specific rules that have been defined for all associated design rule types of that category.Д¬lick on a rule type folder to access a summary listing of all specific rules that have been defined for that type.Д¬lick on the entry for a specific rule in the folder-tree pane (or double-click on its entry in a summary list) to access controls for managing its definition. Signal Integrity - this category offers the following rule types: Signal Stimulus, Overshoot - Falling Edge, Overshoot - Rising Edge, Undershoot - Falling Edge, Undershoot - Rising Edge, Impedance, Signal Top Value, Signal Base Value, Flight Time - Rising Edge, Flight Time - Falling Edge, Slope - Rising Edge, Slope - Falling Edge, and Supply Nets.Placement - this category offers the following rule types: Room Definition, Component Clearance, Component Orientations, Permitted Layers, Nets to Ignore, and Height.High Speed - this category offers the following rule types: Parallel Segment, Length, Matched Lengths, Daisy Chain Stub Length, Vias Under SMD, Maximum Via Count, and Max Via Stub Length (Back Drilling).Manufacturing - this category offers the following rule types: Minimum Annular Ring, Acute Angle, Hole Size, Layer Pairs, Hole To Hole Clearance, Minimum Solder Mask Sliver, Silk To Solder Mask Clearance, Silk To Silk Clearance, Net Antennae, and Board Outline Clearance.Testpoint - this category offers the following rule types: Fabrication Testpoint Style, Fabrication Testpoint Usage, Assembly Testpoint Style, and Assembly Testpoint Usage.Plane - this category offers the following rule types: Power Plane Connect Style, Power Plane Clearance, and Polygon Connect Style.Mask - this category offers the following rule types: Solder Mask Expansion and Paste Mask Expansion.SMT - this category offers the following rule types: SMD To Corner, SMD To Plane, SMD Neck-Down, andвЂ‹ SMD Entry.Routing - this category offers the following rule types: Width, Routing Topology, Routing Priority, Routing Layers, Routing Corners, Routing Via Style, Fanout Control, and Differential Pairs Routing.Electrical - this category offers the following rule types: Clearance, Short-Circuit, Un-Routed Net, Un-Connected Pin, and Modified Polygon.The following rule categories and types are supported in Altium Designer: In the folder-tree pane on the left side of the dialog, each of the supported design rule categories, and types thereof, are listed under the Design Rules folder. The dialogвЂ™s search engine allows it to be used in a straightforward search mode by entering the relevant Name, Type, Category, or Attribute keyword(s) in the main Search field. The dialog is composed of a static pane on the leftВ and a main editing region on the rightВ that changes dynamically with the selection on the left. The dialog is accessed from the PCB EditorВ by selecting DesignВ В» Rules from the main menus. For more information about PCB Design Rules, click here.
