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.
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.
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.
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.
3. What does "Master operation" and "Location operation"each mean?
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)
Master operation
- |
- xxx.cir/landata.rsc (data resource file)
xxx.cir/lanenv.rsc (environment resource file)
![]() |
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.
[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.
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 (*).
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]
5. When I tried to open a schematic file, a message "File (.../landata.rsc) has been changed" was output.
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.
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.
|
![]() |
Condition where symbols cannot be displayed = Symbols cannot be found in /opt/symb/Lib01 |
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).<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
2. Enclose an area around the cell.
[Reason 2.]
Symbol file names in the symbol library have been changed.
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.
7. When searching during parts placement, no parts can be found at all.
[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
Parts Search Path Dialog Box
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. |
Or add a property to each part in the LCDB if necessary.
8. When placing parts in the schematic, no symbol shapes are displayed even though the part names are displayed.
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.
9. Is there any way to scale symbols up or down?
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.
10. I want to change the node size.
When using the Sheet Editor, you can change them from the dialog box shown below.
[Environment] - [Localize Data.RSC] - [Notations]
11. I want to change the value of line width table 0.
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]
12. I want to use negative logic representation for pin names.
The Resource Editor can be started up by double-clicking on landata.rsc from the CR-5000 Design File Manager.
Input %CLK% for the pin name. |
![]() |
13. I want to change the zone display pitch and character size.
In addition to the pitch, you can change colors and reference positions from this dialog box.
[Environment] - [Change Zone Property]
You cannot change the font size indicatated in zone, bacause it is fixed in system.
