Connection - Signals

Changes made to Connection properties, as shown in the following dialogs, only apply to objects that are drawn after changes have been made to the settings, not to existing objects.

 

 

Signals
Signals on Connections

Create connections which transfer signals

  • When the option is checked, the system creates a new signal (for example #12) for new networks. This system-generated signal is associated with the connection line and assigned to the connected pins. In case the pins already have a signal assigned to them, the signal is assigned to the connection and to the connected pins.

  • When the option is unchecked, no new signal is generated for the connection and signals that are already assigned to connected pins are not transferred, via the new connection, to the other pin(s). When generating or changing the signals of connected pins, they are not transferred via the graphical connection. This is important for the wiring if the schematic is to be drawn in a manner similar to a cable harness, where many conductors with different signals, are drawn together in one line.

 

Connections without signal assigned, that were created with this option being unchecked, can be transformed into signal-carrying connections

  • by entering a value in the Signal entry box in the Net View of the Connection Properties dialog. The network automatically becomes a signal-carrying network. The new signal name will be associated to all pins that are connected graphically - even if they had been previously assigned a user-defined signal.

  • If <no entry> is chosen in the above-mentioned Connection Properties dialog, the network will be changed to 'non-signal-carrying'. Signals associated with the connected pins, are maintained and can later be changed independent of each other.

 

By default, the option is checked.

 

For more information, please refer to the section on Connection Types.

Transfer signals on connections between views

Checking this option allows the creation and transfer of signals between connector views.

 

This option and the above one (which refers to originals only) are independent of each other, i.e. a signal transfer between views only is also possible.

 

By default, the option is not checked.
Signals on Symbols

Clear signals when deleting symbols

Defines whether signals on pins are deleted or kept when removing a symbol from a connection:

 

When this option is checked (default setting), the signals on the component- and connector pins belonging to the symbol are deleted. In case conductors are still connected to the pins or views are still placed, the signals are not deleted.

 

When this option is unchecked, the signals on the pins remain unchanged.

Even if not connected view symbols are placed

Note

This check box can only be activated/deactivated if the check box Clear signals when deleting symbols is checked.

 

When the check box is checked and symbols are deleted, the signals are also deleted if there are unconnected view symbols of this device.

 

Note

The signal is not deleted if...

  • the original device symbol is placed

  • a device view with a graphical or physical connection is placed on the pin.

  • a device view is placed and the pin is connected to another device

  • the signal is also routed on a topology sheet

  • a device view is placed and a wire is connected to the pin.

     

    Prerequisite: The check box "Unconnect, if conductor is not routed in a connect line is not active. (Not active in the Settings in the Category Connection in the section Conductors/Wires".
Signal Flow through Connectors

Interrupt signal flow on block connectors

Defines, whether block connectors, that are loaded from the database and placed on a block, will have the characteristic that signals connected to one side, may flow through the connector.

 

When the option is checked, the signal flow into the connector is interrupted.

Interrupt signal flow on normal connectors

Has the same function as described above for block connectors, if the loaded connectors are used other than on a block.
Signal Settings for Copy and Import

Keep user-defined signals

When this option is checked, user-defined signals are kept during copy operations. When it is unchecked, a new system-generated signal is created for user-defined signals.

 

Note

This option is not relevant for Cut&Paste actions.

Keep system-generated signals

When this option is checked, system-generated signals are kept during copy operations. When it is unchecked, a new system-generated signal is created for the system-generated signals.

 

Note

  • System-generated signals within signal classes are treated like user-defined signals.

  • This option is not relevant for Cut&Paste actions.
Signal Classes

Allow signal changes to signals not belonging to same class

When this option is checked, it's possible to assign signals from another signal class or without a signal class to a net that already has an assigned signal from another signal class.

 

When this option is unchecked, it's not possible to assign signals without a signal class to a net with signal assignment.

 

By default, this option is unchecked.

 

For more information, please refer to Signal Class Properties.
Signal Format

Recalculate signal names according to format specification

When this option is checked, all relevant changes of the signal format will automatically be recalculated by default.

 

In addition it can be controlled if every single signal shall be updated at changes or not.
