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 in the Schematic Library Editor only. A total of 34 symbols are available, the associated placement commands for which are located:
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:
The following methods of non-graphical editing are available:
Dialog page: IEEE Symbol
This method of editing uses the IEEE Symbol dialog to modify the properties of an IEEE symbol object.
The IEEE Symbol dialog can be accessed prior to entering placement mode, from the Schematic – Default Primitives page of the Preferences dialog. This allows the default properties for the IEEE Symbol object to be changed, which will be applied when placing subsequent IEEE Symbols.
During placement, the dialog can be accessed by pressing the Tab key.
After placement, the dialog can be accessed in one of the following ways:
The SCHLIB 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 appropriate filtering - by using the SCHLIB Filter panel, or the Find Similar Objects dialog - the panel can be used to make changes to multiple objects of the same kind, from one convenient location.
The SCHLIB List panel allows the designer 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 the designer to target and edit multiple design objects with greater accuracy and efficiency.
