IEEE symbols are non-electrical drawing primitives. They are used for representing logic functions or devices. These symbols enable users to understand the logic characteristics of these functions or devices without requiring specific knowledge of their internal characteristics.
IEEE Symbol objects are available for placement only in the Schematic Library Editor. A total of 34 symbols are available for placement in the following ways:
The IEEE Symbols available for placement are shown in the image below.
After launching a command, the cursor will change to a cross-hair and you will enter IEEE symbol placement mode. The chosen IEEE symbol will appear floating on the cursor.
Additional actions that can be performed during placement are:
This method of editing allows you to select a placed IEEE symbol object directly in the workspace and change its location or orientation graphically. IEEE symbols are fixed with respect to their shape and can be resized only through use of the relevant keyboard shortcuts. As such, editing handles are not available when the IEEE symbol object is selected.
Click anywhere inside the dashed box and drag to reposition the symbol as required. While dragging, the symbol can be rotated (Spacebar/Shift+Spacebar), mirrored (X or Y keys to mirror along the X-axis or Y-axis), or resized (+/- keys on numeric keypad).
The following methods of non-graphical editing are available:

This method of editing uses the associated Properties panel mode to modify the properties of an IEEE Symbol object.
During placement, the IEEE Symbol mode of the Properties panel can be accessed by pressing the Tab key.
After placement, the IEEE Symbol mode of the Properties panel can be accessed in one of the following ways:
The Properties panel supports multiple object editing, where the property settings that are identical in all currently selected objects may be modified. When multiples of the same object type are selected manually, via the Find Similar Objects dialog or through a Filter or List panel, a Properties panel field entry that is not shown as an asterisk (
*) can be edited for all selected objects.
The SCHLIB List panel allows you to display design objects from one or more documents in tabular format, enabling quick inspection and modification of object attributes. Used in conjunction with appropriate filtering - by using the SCHLIB Filter panel, or the Find Similar Objects dialog - it enables the display of just those objects falling under the scope of the active filter – allowing you to target and edit multiple design objects with greater accuracy and efficiency.
