Bus Entries can be used to connect Wires to a Bus.

Summary

A bus entry is an electrical design primitive that is used to connect a wire to a bus line. It has the ability to allow two different nets to connect to the same point on a bus, if this was done using wires the two nets would short. If this capability is not required, bus entries do not need to be used.

Availability

Bus entries are available for placement in the Schematic Editor only, by clicking Home | Graphical Elements |  from the main menus.

Placement

After launching the command, the cursor will change to a cross-hair and you will enter bus entry placement mode.

  1. Click or press Enter to place a bus entry at the cursor position.
  2. Press Spacebar to rotate the bus entry anticlockwise (in steps of 90°), press Shift+Spacebar to rotate clockwise.
  3. Press the X or Y keys while in placement mode to mirror the bus entry along the X-axis or Y-axis respectively.
  4. Continue placing bus entries or right-click or press Esc to exit placement mode.

While attributes can be modified during placement (Tab to bring up associated properties dialog), bear in mind that these will become the default settings for further placement.

Graphical Editing

To move a bus entry, click and hold on it, (the cursor will jump to the nearest electrical hotspot), then move it to the new location.

An object that has its Locked property enabled cannot be selected or graphically edited. Double click on the locked object directly and disable the Locked property, to graphically edit the object.

Non-Graphical Editing

The following methods of non-graphical editing are available:

Via an Associated Properties Dialog

Dialog page: Bus Entry

This method of editing uses the Bus Entry dialog to modify the properties of a bus entry object.

Edit the properties of the Bus Entry in the Bus Entry dialog.

The dialog can be accessed during placement by pressing the Tab key.

After placement, the dialog can be accessed in one of the following ways:

  • Double-clicking on the placed bus entry object.
  • Placing the cursor over the bus entry object, right-clicking and choosing Properties from the context menu.

Via the SCH Inspector Panel

Panel page: SCH Inspector

The Sch Inspector panel enables the designer to interrogate and edit the properties of one or more design objects in the active document. Used in conjunction with the Find Similar Objects dialog, the panel can be used to make changes to multiple objects of the same kind, from one convenient location.
