Data Conversion to Use the Layout XL Schema

This topic explains how you decide whether you need to convert your existing data to use the new Layout XL schema; what happens to the data during the conversion; and how to run the conversion commands.

You need to convert data to the Layout XL schema, if your schematic library or layout design data uses any of the following features:

Library-level component type information stored in a data.dm (or prop.xx for earlier releases) file in the library directory, or design-level component type overrides stored as an lxComponentType property on the layout view.
The following properties (or their CDF equivalents) stored on a symbol or schematic view.
lxMfactorSplit Property lxParamsToIgnore Property lxParamsToIgnoreForCheck Property lxRemoveDevice Property lxRounding lxStopList Property lxUseCell Property lxViewList Property
After your data has been converted, if you change the name of an instance, or change it from vectored to non-vectored, then Configure Physical Hierarchy will not be able to find the converted properties for the new instance name.
These properties will not be converted if the variable CPH_USE_SCHEM_PROP is enabled.

Automatic Mode

If you use none of the features described above, then you do not need to convert your data to use physical configuration views.

When you start Layout XL, set the Configuration option to Automatic in the Startup Option form. Layout XL creates a temporary physical configuration view, handles all operations related to the physical configuration view automatically, and removes the temporary view again when it is no longer required; that is., when you convert your data to use physical configuration views or edit the automatic configuration and save it.
