Pcb rules and constraints editor _ online documentation for altium products

The dialog is composed of a static pane on the left and a main editing region on the right that changes dynamically with the selection on the left. Database unit testing Left-Hand Pane

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. I data recovery software free download The following rule categories and types are supported in Altium Designer:

• Electrical – this category offers the following rule types: Clearance, Short-Circuit, Un-Routed Net, Un-Connected Pin, and Modified Polygon.


• Routing – this category offers the following rule types: Width, Routing Topology, Routing Priority, Routing Layers, Routing Corners, Routing Via Style, Differential Pairs Routing,

• Testpoint – this category offers the following rule types: Fabrication Testpoint Style, Fabrication Testpoint Usage, Assembly Testpoint Style, and Assembly Testpoint Usage.

• High Speed – this category offers the following rule types: Length, Matched Lengths, Maximum Via Count, Parallel Segment, Daisy Chain Stub Length, and Vias Under SMD.

• 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,

• Placement – this category offers the following rule types: Component Clearance, Room Definition, Component Orientations, Permitted Layers, Nets to Ignore, and Height.

• Signal Integrity – this category offers the following rule types: Flight Time – Falling Edge, Flight Time – Rising Edge, Impedance, Overshoot – Falling Edge, Overshoot – Rising Edge, Signal Base Value,

Signal Stimulus, Signal Top Value, Slope – Falling Edge, Slope – Rising Edge, Supply Nets, Undershoot – Falling Edge, and Undershoot – Rising Edge.

Click on the root folder to access a summary listing – in the main editing region of the dialog – of all specific rules that have been defined for all design rule types across all categories.

Click 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.

Click 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.

• New Rule – use this command to create a new rule of the currently selected rule type. O review database The new rule will be added to the folder-tree and will also appear in the summary list for that rule type. Database in recovery The rule name will appear bold to distinguish

• Rule Definition – if a specific rule is selected in the left-hand pane, this region will present the following controls for defining that rule.

• Unique ID – the unique identifier for the rule. Data recovery wizard professional Every rule is itself a design object, and hence a tangible piece of data. Data recovery open source The use of an ID ensures uniqueness. Gif database Where the Unique ID really comes into play however, is for a rule that

has been created within the schematic domain. Data recovery lifehacker When adding design rule parameters to objects on a schematic, a unique ID is given to each rule parameter. Top 10 data recovery software 2014 The same IDs are given to the corresponding design rules that are created in the PCB. Database gale With

this Unique ID, the constraints of a rule can be edited on either the schematic or PCB side and the changes pushed through upon synchronization.

• Test Queries – click to open the Test Queries Result dialog that shows the number of objects affected by the rule taking into account rule specializations you defined. This allows you to see

if there are objects that respond to the query and also to check that the set of objects affected by the filters and rules is what you desire.

• Rule Scoping Controls – this region provides controls for determining the scope of the rule in terms of the objects it applies to or between. Database life cycle See the Rule Scoping Controls section below for more detail

• Constraints – this region of the dialog presents the constraints applicable to the type of rule being edited. Data recovery dallas Use the various controls to configure these constraints as required. Data recovery usb Press F1 over the constraints region

For a unary design rule, controls will be provided to define a single rule scope. Database 4th normal form Use the options available in the Where The Object Matches region to help build the query expression, which will be presented in the region to its right.

For a binary design rule, controls for Where The First Object Matches and Where The Second Object Matches will be provided to define both rule scopes. V database in oracle Use the available drop-downs of each to help build

• Net – generate a scope query that targets all objects in a specific net. Data recovery tampa An additional drop-down appears from which you can select the desired net from a list of available choices, including No Net.

• Net Class – generate a scope query that targets all objects in a specific net class. R studio data recovery with crack An additional drop-down appears from which you can select the desired net class from a list of available choices, including All Nets.

• Layer – generate a scope query that targets all objects on a specific layer. Database uses An additional drop-down appears from which you can select the desired layer from a list of available choices.

• Net and Layer – generate a scope query that targets all objects in a specific net and on a specific layer. Database history Two additional drop-downs appear from which you can select the desired net and layer.
