Add Net

The Add Net dialog allows you to add nets to a schematic sheet. You can define labels for the nets, and specify that they are automatically incremented when multiple nets are added. It is displayed by clicking Home > Add > Net on the eCADSTAR Schematic Editor ribbon.

Dialog

Value   Description
Net Label   Allows you to define the label that is associated with a net. The value that you specify is shown in the Net Label box, in the Properties Panel. For the Add Net, Net/Bus and Increment Net commands and in the Properties Panel, if you attempt to change a label to one that already exists, then a confirmation dialog is immediately displayed. This asks whether to merge the nets.
  • Click Yes in the dialog to merge the nets.
  • Click No in the dialog to cancel the operation.

The dialog is shown if duplicate net labels exist for the following objects.

  • Net Bus Component: Sheet connector
  • Component: Global connector
  • Component: Power (Global connector)
  • Component: Ground (Global connector)

Duplicate net labels may be detected on all sheets in the circuit, including instance hierarchy. However, consider the following for global connectors.

  • The confirmation dialog is shown if the label of a global connector matches the label of a top sheet net.
  • The confirmation dialog is not shown if a net in the hierarchy that is not connected to a global connector matches the label of a net on the top sheet.
Note
If the bus name “X[1-4]” exists, and Use array syntax is selected in the Assignments dialog, then:
  • The confirmation dialog is shown for “X[1]”.
  • The confirmation dialog is not shown for “X1”.
If Use array syntax is not selected in the Assignments dialog, then:
  • The confirmation dialog is shown for both “X[1]” and “X1”.

For a connected net, if you specify a label when one is not already assigned, then the net names that are listed in the Net/Bus command, Suggested labels box, are excluded from this check. They are also excluded if the specified label is contained within the existing name. For example, if you specify a label for the highlighted bus below, then:

  • A warning is not shown for “A[1]”, ”A[2]”, ”A[1-3]” or “A[3-2]”.
  • A warning is shown for “A[4]”, ”A[1-4]” and ”A[4-2]”.

For an unconnected net, specified net names are not excluded from this check.

If this value is blank and a connection between two different named nets is made, a prompt will be shown asking the user to select which named net should be used. These nets will then be merged together.

  Displays the Select Net Label dialog. This allows you to select a net label from those that already exist in the design, or if the connection has already been started, based on the start node.
Auto Label    
  None The net label that you specify in the Net Label box is used for all the nets that you add.
  Increment For net labels that contain a numerical suffix, this setting allows you to automatically increment the suffix when you add multiple nets.

If a net label contains a numerical suffix, then it is automatically incremented when you add multiple nets. For example, if you specify a net label of A100, then subsequent nets that you add are assigned net labels in the following sequence: A101, A102, A103. Net labels are also incremented if they contain numerical suffixes that are within square brackets
  Bus/Pin The net label is set automatically from the bus (next unused name in bit order) or pin (pin label), based on the following priority:
  • Part name of Terminate with symbol
  • Bus start node
  • Bus end node
  • Pin start node
  • Pin end node

When this is selected, the Net label field is disabled.

Note
When Port Net Label is ON and the net connects to a named connector ( Global/Sheet/Hierarchy Connector, Power and Ground), the net label is set by the Port Net Label.
Wiring Mode   Select the input mode for nodes. If Auto wiring or Semi-auto Wiring is selected, pins that are in the way of the net being routed are automatically avoided.
 

Auto Wiring

Allows you to specify only the start and end points. Intermediate nodes are generated automatically.

Note
  • If selected, then Through Connection is automatically set to OFF
  • If Through connection is set to ON, then Manual wiring is automatically selected in the Wiring Mode box.
 

Semi-auto Wiring

Specify intermediate nodes after specifying the start and end points.

 

Manual Wiring

Specify nodes sequentially from the start point.

Angle Lock   If Manual Wiring is selected in the Wiring Mode box, then you can specify that nets can only be placed on the canvas in increments of 45 degrees or 90 degrees, or can be placed at any angle.

 

Free Nets can be placed on the canvas at any angle.
  45-degree Nets can only be placed on the canvas in increments of 45 degrees.
  90-degree Nets can only be placed on the canvas in increments of 90 degrees.
Through Connection   Allows you to connect objects when placing a net on a schematic sheet; see Through Connection.
Note
If Auto Wiring is selected in the Wiring Mode field, then Through Connection is automatically set to OFF.
  ON Objects on the placed net are connected. If selected, then Manual wiring is automatically selected in the Wiring Mode box.
  OFF Objects on the placed net are not connected.
Ripper Direction   Selects the direction in which the ripper is dragged.
  Clockwise Tilt the ripper direction clockwise, against the direction in which the T-shape section of the bus, or the net connected to the bus, is added.
  Counterclockwise Tilt the ripper direction counterclockwise, against the direction in which the T-shape point of the bus, or the net connected to the bus, is added.
Specify Color   Allows you to specify the color of the net.
  ON If selected, the Color box is made available.
  OFF If selected, the Color box is made unavailable.
Color box   Click the Color box to select a color in the Select color dialog.
Line Width   Select the line width of the net by selecting it in the Line Width box, or select <DEF> to specify that the default value is used.
  • The values that are listed are set in the Line Width tab, in the Assignments Dialog.
  • The default Line Width value for nets is set in the Line Width tab, Default Line Width section, Net box, in the Assignments Dialog.
Terminate with Symbol   Allows users to terminate the net with either a Power, Ground, Sheet or Global Connector.
  ON If selected, the net is terminated on a Symbol. This is executed by either double clicking the left mouse button or clicking the right mouse button and selecting finish. This enable the Symbol and Rotation step fields in the dialog.
  OFF If selected, the net will not terminate with a symbol. This disables the Symbol and Rotation step controls.
Symbol   Enabled when Terminate with Symbol is ON. Lists all the power, ground, sheet, and global connectors, that are available in the eCADSTAR Library Editor to terminate the net on.
Rotation step   Enabled when Terminate with Symbol is ON. Specify the angle of rotation for the specified symbol (real number greater than -360 but smaller than 360).
