1. Questions about the Schematic Editor

1. When I tried to open a schematic sheet, an error "File (xxx.sht) is locked"

is encountered and the sheet is opened in Reference mode.


A locked file (xxx.___) is created when editing schematic sheets.

This is provided to inhibit a sheet file from being edited by two users at the same time. If a locked file is displayed except when the schematic is being edited, check the user host in the message dialog box to make sure that no one else is editing the schematic. Then erase the lock file and open the sheet file again.

A locked file also remains when you force-quit System Designer, leaving the sheet file open, or when System Designer terminates abnormally.

The locked file is created in the circuit directory /log/xxx.___.

2. When I tried to open a schematic file, a message

"File (XXX.cir/landata.rsc) cannot be opened"

was output and I could not open the file.


The schematic file cannot be opened because landata.rsc, which is referenced by the file, cannot be referenced.

Schematic files always have a landata.rsc (data resource file) and lanenv.rsc (environment resource file) assigned to them.

The path to each resource file is written in a resource path file named "xxx.cir/rcpath." If the resource file written here cannot be referenced, the schematic file cannot be opened either.

Double-click on rcpath from the CR-5000 Design File Manager to check the path to the resource file, and correct it if necessary.

If you cannot open the file even though the path is correct, you may not have access permission to the file. Please check the file's access permission.




3. What does "Master operation" and "Location operation"each mean?


Various work environments in which you edit schematics and settings for directories that contain symbols and parts are registered in data resource files (landata.rsc) and environment resource files (lanenv.rsc).

When you create a new file, the following files are referenced:

$ZDSROOT/info/landata.rsc (data resource file)
$ZDSROOT/info/lanenv.rsc (environment resource file)
With a master operation, you proceed with your design work while directly referencing the files under $ZDSROOT.

Master operation

|
Each schematic references common source files.

When you perform "Localize Resource" on creation of the circuit directory, the following files will be created.
xxx.cir/landata.rsc (data resource file)
xxx.cir/lanenv.rsc (environment resource file)
These files are created by copying from the files under $ZDSROOT. Once landata.rsc and lanenv.rsc have been created in the circuit directory, the files under $ZDSROOT are no longer referenced. Thus, in a local operation, you proceed with design work while accessing the resource files in the circuit directory.

If you click this checkbox and create a schematic, the operation will be in the local mode.

Local operation
|
Individual resource files are referenced for each schematic.
To change from the Local to the Master operations, choose

[Environment] - [Initialize Environment]

as you save the file. Landata.rsc and lanenv.rsc will be deleted from the circuit directory, and the operation will change to Master operation.

To change the operation of the resource after creating the circuit directory (local operation <-> master operation), edit the file path described in xxx.cir/rcpath to change the target of reference for resource.




4. When placing symbols in the schematic, no symbol name is displayed even when I've selected a symbol library directory.
Also, library names are marked with asterisks (*).



Have you gone directly to the directory where symbols are stored?
Is the directory containing that symbol registered in the symbol search path?

If you select the symbol contained in the library which is not registered in the symbol search path, the library name will be displayed as "*". You must preset the directory of the library you want to use in the data resource. Follow the steps below to confirm that the symbol library you want to use is registered in the symbol search path.

[Environment] - [Localize Data.RSC] - [Symbol Path]

If no library is registered, you need to register it. Use landata.rsc described in the circuit directory (xxx.cir)/rcpath.

For local operation, go to [Localize Data RSC] to make temporary change with the symbol path table displayed and [save] the schematic. Thus the edit contents will be reflected on landata.rsc referenced by the schematic.




5. When I tried to open a schematic file, a message "File (.../landata.rsc) has been changed" was output.


This is a warning message indicating that the contents of the data resource file (landata.rsc) referenced in your schematic has been updated.

Each schematic always has its inherent data resource file (landata.rsc) and environment resource file (lanenv.rsc).

Normally, the following files are referenced during Master operation:

$ZDSROOT/info/landata.rsc
$ZDSROOT/info/lanenv.rsc

During Local operation, the following files are referenced:

xxx.cir/landata.rsc
xxx.cir/lanenv.rsc

If the above resource files were updated when you saved the schematic previously, a message dialog box is displayed.

Depending on the file contents that have been updated, it's possible that no symbols will be displayed. Be careful when editing the resource files.

Frequently Asked Questions and Answers

No symbols are displayed when I open a schematic file.




6. No symbols are displayed when I open a schematic file.



There are two reasons that symbols may not be displayed.

[Reason 1.]
The symbol path defined in the data resource file (landata.rsc) does not coincide with the actual directory name.

=Before the change=
Path number - 2 = /symb/Lib01
 
 
 
=After the change=
Path number - 2 = /opt/symb/Lib01
Condition where symbols cannot be displayed
= Symbols cannot be found in /opt/symb/Lib01
The symbols used in schematics are always loaded from the symbol library set in landata.rsc (= the directory that contains symbols).

If the symbol path definition in the referenced landata.rsc has been changed or if the symbol library directory name has been changed, the symbols may no longer be searched unless the file descriptions are corrected.

Check the descriptions in landata.rsc against the directory name where symbols are actually stored and correct the landata.rsc accordingly.

Alternatively, write a new symbol library path in landata.rsc and make sure the symbols are loaded from the new symbol library.

- Operations for editing landata.rsc -

<Master operation>

After closing the file, edit $ZDSROOT/info/landata.rsc (data resource file).
(The data Resource Editor is started up by double-clicking on landata.rsc from the Design File Manager.)

<Local operation>

[Utilities] - [Localize Data.RSC] - [Symbol Path]

After changing the contents using the data Resource Editor, save the schematic sheet.

Symbol Search Path Dialog Box

- Operations for loading symbols from the new path number -

In either case, this operation is performed while symbols that are no longer displayed are selected.

In case of searching symbols from symbol library described in landata.rsc
[Utilities] - [Reload Symbol Figure] - [Load Symbol Using Current Symbol Path]
After changing the contents using the data Resource Editor, save the schematic sheet.

In case of loading symbols from the specified pass number.
From the keyboard, enter the command shown below into the command input area.
(SwapSymbol SearchPath:n) n = Path number

To choose a symbol that is not displayed
1. Move the focus to a component cell, then

2. Enclose an area around the cell.




[Reason 2.]
Symbol file names in the symbol library have been changed.

Once a symbol is placed on the schematic, the symbol path and the symbol file name always reside in the computer.

Therefore, if the symbol file name has been changed, symbols cannot be loaded and, hence, cannot displayed.

Restore the symbol file name to the previous one or replace the symbols themselves.

- Operations to check the current symbol library path and symbol file name -

1. Move the focus to a component cell and enclose an area where a symbol is present but not displayed.

2. Once the symbol is selected, select [Attribute]-[Change Attribute], or click to display the Change Attribute dialog, and confirm the result with the System Property Tab.

Frequently Asked Questions and Answers
I want to replace a symbol figure which has already been placed in the schematic with another one.



7. When searching during parts placement, no parts can be found at all.



There are two possible reasons for this problem.


[Reason 1.]
The LCDB (parts info library for schematic design) to be used is not set in the data resource file (landata.rsc).

The LCDB to be used must be set in landata.rsc before you can use it. Choose

[Environment] - [Localize Data.RSC] - [Components Library Path]
to bring up a list of LCDBs and check whether the desired LCDB exists.
If it does not exist, add the library path to the parts path of landata.rsc described in xxx.cir/rcpath.

Parts Search Path Dialog Box

[Reason 2.]
No parts that conform to the search conditions are registered in the LCDB (parts info library for schematic design). Alternatively, the search conditions themselves are at fault, as they are not defined as part properties.

The conditions under which parts are searched must be set in the parts placement resource file (srchprts.rsc).

If no part that conforms to the search conditions is found in the LCDB during part placement, the search result will be 0.

Also, if the property used as a search condition is not defined as a part property in the LCDB, the search result will be 0.

Also, if the property used as a search condition is not defined as a part property in the LCDB, the search result will be 0.

Although a search was run for parts whose Partskind property = IC, no occurrence was found.

No parts whose Partskind property is IC exist at all.

Or the property Partskind itself is not defined in the LCDB.

In either case, review the definition of srchparts.rsc first.

Or add a property to each part in the LCDB if necessary.

If no circumstances have changed after reviewing above-mentioned two points, there is a possibility that something is wrong with rlt file for LCDB. Re-start schematic editor after deleting rlt file and save LCDB.

Frequently Asked Questions and Answers
I want to know which resource files are referenced when placing parts in the schematic.
I also want to know what these files are used for.




8. When placing parts in the schematic, no symbol shapes are displayed even though the part names are displayed.



This is because the symbol files defined in the component information of the specified part do not exist in the symbol library.

When you choose a part name during part placement, the symbol files defined in the component information in the LCDB (parts info library for schematic design) are searched from the symbol library sequentially, beginning with number 0.

Check whether the symbol files defined in the LCDB are registered in one of the symbol libraries. If necessary, register files in a symbol library or create symbols.




9. Is there any way to scale symbols up or down?



There are two methods for scaling symbols. One allows you to scale symbols individually, one at a time; the other lets you scale all symbols collectively at one time.

1. Scaling symbols individually
When placing symbols, choose [Symbol Scale] from the Assist menu.

2. Scaling all symbols collectively
Choose [Environment] - [Command Default] to specify a scaling factor to be applied for all symbols.

You cannot change the scale factor after placing symbols into position.




10. I want to change the node size.



The node sizes are defined in the data resource file (landata.rsc).

When using the Sheet Editor, you can change them from the dialog box shown below.

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

The Resource Editor can be started up by double-clicking on landata.rsc from the CR-5000 Design File Manager.

For Master operations, changes made by the Sheet Editor are temporary, and are not saved.



11. I want to change the value of line width table 0.


Line widths are defined in the data resource file (landata.rsc).

Defined line widths can be changed, except for line width number 0. The line widths for number 0 is fixed to [0.0].

When a schematic is open, you can change them temporarily but cannot save the changes.

[Environment] - [Localize Data.RSC] - [Line Width]

The Resource Editor can be started up by double-clicking on landata.rsc from the CR-5000 Design File Manager.

For Master operations, changes made by the Sheet Editor are temporary, and are not saved.




12. I want to use negative logic representation for pin names.



Negative logic representation is defined in the data resource file (landata.rsc).

The Resource Editor can be started up by double-clicking on landata.rsc from the CR-5000 Design File Manager.

Define the first and last characters for negative logic representation and enclose the character string you want to be represented by negative logic with those characters.




Input %CLK% for the pin name.

You can't change the setting from [Localize Data.RSC] in Schematic Editor.



13. I want to change the zone display pitch and character size.


When creating new schematics, the zone display pitch is defined in the environment resource file (lanenv.rsc). Therefore, you can change it by editing lanenv.rsc unless you have already created a schematic sheet.

The Environment Resource Editor can be started up by double-clicking on lanenv.rsc from the CR-5000 Design File Manager.
Once you have created a schematic sheet, use the dialog box shown below to change the zone display pitch.

In addition to the pitch, you can change colors and reference positions from this dialog box.

[Environment] - [Change Zone Property]

You can set the offset from the starting point of the zone display.

You cannot change the font size indicatated in zone, bacause it is fixed in system.
