Connections: Principle

In circuit diagram pages, connection points of components or connection symbols which are precisely opposite one another, horizontally or vertically, will automatically be connected. This is called autoconnecting, and the connection lines created this way are called autoconnect lines. When inserting and moving symbols, a preview of the autoconnecting lines is shown.

The autoconnect lines are first purely graphic until the connections are generated. This occurs automatically for many actions (e.g., when a page is opened) but can also be performed manually at any time. The individual connection can get its data from project settings, potentials, or connection definition points.

You use connection symbols such as T-nodes or double junctions to draw the course of the connections. Connection junctions and double junctions can be represented either as simple points or with target specification. In the latter case, the connection sequence is directly visible and is determined by the internal logic of the connection symbol (target tracking).

Connections are displayed in the schematic according to the specified line data. You can specify the line data for the project, for potentials, or for individual connections.

Connection sources and targets

A connection always has information about what it is connected to at both ends, the source and the target. The device tags of the connected functions are compared by default to determine the source and target. The sorting of the structure identifiers in the structure identifier management will be used for these comparisons; the "smaller" device tag will become the source. In addition, unplaced connections will be considered as well. If there are more than one connection between two functions, then one function is always the source for all connections, and the other function is always the target for all connections.


Exchange source and target

With the new menu item Project data > Connections > Exchange source and target, you can respectively exchange the source and target including the source- and target-dependent connection properties for the connections marked in the graphical editor, in the connections navigator, in the page navigator or in the layout space navigator.

In addition, the sequence of the routing paths passed through is reversed in the properties Layout space: Routing track (ID 31095) and Topology: Routing track (ID 20237).

If a connection exists in several representation types in a project, source and target are exchanged globally. The direction of the connection is then the same at all representation types.

The following connection properties are exchanged:
