26. What is the difference between a property and a property viewer?



Each object has properties. Properties provide information on an object's name and characteristics. (For example, reference and part name are properties of component cells.)

However, properties are the information that is internally recognized by the system and not displayed on schematics.

Therefore, the data that is input to display properties is the property viewer.

Property viewers are required for certain properties, such as references and pin labels, which are represented by character strings.

For properties that are input for symbols and pins, if you know that they need to be displayed, it is convenient to input property viewers when registering symbols rather than entering them individually on schematics later.




27. Although I defined a reference and other properties, they are not displayed on the schematics.



If you want the reference and other properties you have defined to be displayed on schematics, input property viewers.

Or double-click on the cell for the property name you want to display in the Change Attribute dialog box. The selected cell changes color to sky blue. (You may perform this operation instead of entering data in Property Viewer.)

A: [Place] - [Property Viewer]

Property Viewer Dialog Box

Choose a property from the "Property list" by clicking on it.

Change the colors and display positions as necessary.

Click <<Apply>>.

When you bring the focus onto the canvas, the property viewer is displayed in a drag shape. Click at a position on the canvas where you want to display the property viewer.

B: Select a symbol, then choose [Attribute] - [Change Attribute].

Change Attribute Dialog Box

Double-click on the property name of the property you want to display to change its color to sky blue and choose <<Apply>>.


If you have changed the cell for the given property name from sky blue to white in the Change Attribute dialog box, Property Viewer is no longer displayed. However, because the property name remains as an object, it becomes the target of object selection.


Frequently Asked Questions

When focus is the property viewer, those whose display is turned off can be selected. Why?




28. The positions at which property viewers are displayed for input/pins differ for each pin.



The positions of the automatically generated property viewers are determined automatically based on the position of each relevant object.




29. When focus is the property viewer, those whose display is turned off can be selected. Why?



In System Designer, everything that exists is recognized as an object regardless of whether they are displayed or not.

Property viewers are objects used to input and display properties. If a property viewer is not needed, delete it (don't just turn off its display).

Note that if you delete a property viewer, the property itself is retained.




30. When a property is not defined, the property viewer is displayed as @xxx. I don't want it to be displayed.



If a property viewer is input before the property itself is defined, it is displayed as "@ + property name."

Choose [Environment] - [Localize Data.RSC] - [Notations].

The Notations, etc dialog box will appear.

The "Displayed Property Name Length" parameter in this dialog box is set to the length of the character string "@XXX." Set this value to 0.



31. Although I deleted a net name, the property viewer "@netLabel" remains intact.



When you input a net name, a property viewer for the net name is input simultaneously.

However, this property viewer is not automatically deleted. You must delete it manually. Therefore, even when you have deleted the net name, @netLabel remains intact.

Delete property viewers that you don't need.




32. I want to change the object colors.



Each object has its inherent properties.

Color is one of those properties. Therefore, to change the color of an object,

first select the object, then choose

[Attribute] - [Change Attribute]
to bring up the Property Setup dialog box. Specify the color you want in System Property Tab.

Conponent Cell Property Viewer

Property Setup dialog box

The default color of each object is defined as a default property in the environment

resource file (lanenv.rsc). This is the color that is used when you input an object.

Default Attributes Dialog Box



33. I want to edit the character comments which I input directly into a symbol file on the schematics.



The data input in symbol files cannot be edited on schematics. To edit such data, therefore, open the symbol file when editing symbol figure and edit the data.

On the other hand, in cases where property viewers have been input in the symbol file, once the properties are defined you can display the values at any time.

Therefore, if the character strings need to be changed on the schematics, we recommend that property viewers, and not the character comments, be input in the symbol file.

Cases where the management number is input in a sheet frame symbol Cases where the property viewer for the management number is input in a sheet frame symbol
If you want to add properties that are not available to the system, you must write them in PropSpec (property definitions file) before adding them.




34. Although I replaced a part, the position of the previous property viewer is retained.



You can change the setting so that the position of the property viewer set before replacing components is not retained. To do this, take off the check of [Keep property viewers] in the "Swap Components" dialog.

Specifications of each [Swap symbols] [Reload Symbol Figure] [Reload Parts Info] function retain the position of previous property viewer.
If you want to avoid the above,operate as follows.
  1. Delete the Property viewers of each component.
  2. Then excute each command ([Swap symbols],[Reload Symbol Figure],[Reload Parts Info]).

How to Delete Property viewer.
Select Property viewers you want to delete, then choose [Edit]-[Delete] or just use Delete key in keyboard.

Property viewers can not be deleted in Change Attribute Dialog. When you use Change Attribute Dialog, the viewers look like being deleted but they are not deleted in fact.
So property viewers must be deleted according to the above-mentioned operation .




35. I want the pin numbers and pin names that have already been input to be turned off from the display collectively on the schematics.



Execute one of the following two methods.

1. Set the focus to "Pin." After selecting the entire schematic, choose [Attribute] - [Change Attribute]. The Property Setup dialog box will appear. Double-click on the "Pin Number" or "Pin Name" cell in this dialog box.
(-> The color changes from light blue to white.)

2. Choose [Edit] - [Find] to bring up a dialog box, then click [OK] or [Apply].
Next, choose [Attribute] - [C
hange Attribute] to bring up the Change Attribute dialog box. Turn the pin number or pin name display off in this dialog box.


Note that if you have deleted pin number or pin name property viewers when registering symbols, they are not displayed even if you set properties on schematics.

(However, the symbols that have already been input in schematics are not affected.)




36. Although I edited a symbol file, but the changes I made are not reflected in the symbols on the schematic.


If some change has been made to the symbol file after entering symbols in the circuit diagram, properties cannot be changed--even though changes of shapes are reflected in real time--unless you reload the symbol file.

After selecting symbols, execute [Utilities] - [Reload Symbol Figure] - [Load Symbol Using Current Symbol Path].

About the reload command function for the symbol figures.

Load Symbol Using Current Symbol Path
The selected component is reloaded from the same path and same file name into the schematic.

Load Symbol by Search
Symbols in the same file as that of the selected symbol are searched sequentially beginning with symbol path number 0. The file is replaced with the first occurrence of file.

Changes of pin information cannot be reflected using [Reload Symbol Figure]. Use [Swap Symbols] to change the diagram with the symbol that is affected by changes of pin information.

Frequently Asked Questions

I want to replace a symbol figure which has already been placed in the schematic with another one.
