Troubleshoot Editing

You can face following issues while editing in Layout XL:

Components Move Slowly

If you find that the Move command works too slowly, especially when you have many iterated instances, turn off the display of incomplete net flight lines or display only nets that are relevant to the current task.

Generate Layout Form Does Not Keep Values from the Last Entry

The Generate Layout form displays default values each time it opens, it does not carry over values from the previous time the form was displayed.

To use predefined settings, set the appropriate environment variables in your .cdsenv file before you start Layout XL. Alternatively, you can load predefined cellview information from another OpenAccess cellview. For more information, see .

Parameters Not Updated

If the parameters are not updated the way you expect, check for the presence of the lxParamsToIgnore Property on components of your design.

Schematic Not Editable

If you cannot make changes to the schematic,

Check that the schematic is editable. (If it is, the word “Editing” is displayed in the window banner; if it is not, the word “Reading” is displayed.)
If it is not editable, make it so using the File – Make Editable command.
Check with your system administrator that you have a license for the Virtuoso Schematic Editor (product 302).

Warning to Update Your Design Appears at Startup

When you open a design in Layout XL and an Info window appears, it means that the schematic has been changed after the last time the layout was changed, so the layout does not represent the latest version of the design.

You can check the layout against the changed schematic using the layout window Check Against Source command and then update the layout view using either the Update Components And Nets or Define Device Correspondence commands as needed.
