Schematic Library Conversion
The schematic library conversion is typically performed by the library designer, who provides a complete library and attributes mapping (LAM) file for the libraries you are using.
The schematic library conversion converts:
-
Library-level component types stored in CDF files or (if none exist in CDF) in the
data.dmfile in the library directory.
This data is converted into a LAM file called library/.cadence/dfII/cph/lam/cph.lam.
If the LAM file already exists, any new information is appended to the existing file. Where there is a conflict, existing information is overwritten with new information. If there is no data to be converted, then no LAM file is created or updated.
If the same component type is defined with identical attributes in two different libraries, the definitions are merged into a single definition in the LAM file. All required cells are then assigned to that single component type. -
The properties (or their CDF equivalents) set on a symbol view for a cell.
This data is also converted into the LAM file under the same conditions as described above. After the conversion, the properties remain on the symbol view but are considered obsolete. -
The properties (or their CDF equivalents) set on a schematic view for a cell.
The library conversion determines whether a view is a schematic view based on its type, not its name.
This data is converted into the physical configuration (physConfig) view for the cell in question. If the view already exists, any new information is appended to the existing view. Where there is a conflict, existing information is overwritten with new information. If there is no data to be converted, no physical configuration view created or updated.
After the conversion, the properties remain on the schematic view but are considered obsolete.
You can convert schematic libraries manually using the cphUprevLibrary SKILL function.
