The OpenAccess Defaults Panel

The OpenAccess Defaults panel is brought up with the Defaults button in the OpenAccess Libraries panel. This panel is only available when an OpenAccess database is being accessed with the plug-in, in which case the OpenAccess Libs button appears in the File Menu.

Each of the entry areas tracks a variable that is used to set default behavior in the interface to the OpenAccess database.

Library Path
This entry tracks the setting of the OaLibraryPath variable. It can be set to a full path to a directory. If a library to be accessed is not listed in the lib.defs (or cds.lib) file, the system will look for the library as a subdirectory of the directory path given. This allows use of OpenAccess libraries that are hidden from other tools.

Default Library
This tracks the setting of the OaDefLibrary variable. It can be set to a library name found in the lib.defs (or cds.lib) file, or to a subdirectory of the Library Path if any. This will be used when reading from or writing to the OpenAccess database, if the library name is not otherwise specified.

Default Tech Library
This tracks the setting of the OaDefTechLibrary variable. It can be set to a library name found in the lib.defs (or cds.lib) file, or to a subdirectory of the Library Path if any. When a library is created, it will attach the technology database associated with the library name entered, if any. If the named library has an attached technology, the same attachment will be applied to the new library. Otherwise, the new library will attach the local technology database of the named library.

Default Layout View
This tracks the setting of the OaDefLayoutView variable. It specifies an alternate view name for physical layout data. If not specified, the default layout view name is ``layout''.

Default Schematic View
This tracks the setting of the OaDefSchematicView variable. It specifies an alternate view name for electrical schematic data. If not specified, the default schematic view name is ``schematic''.

Default Symbol View
This tracks the setting of the OaDefSymbolView variable. It specifies an alternate view name for electrical symbol data. If not specified, the default symbol view name is ``symbol''.

Default Properties View
This tracks the setting of the OaDefDevPropView variable. It specifies an alternate view name for the simulator-specific view which (if present) provides values for certain device properties (from the Common Design Framework (CDF) database). If not specified, the default simulator view name is ``HspiceD''. This specifies Hspice compatibility in Virtuoso, which is a good match for WRspice.

Dump CDF files while reading
This check box tracks the set/unset status of the OaDumpCdfFiles variable. When checked, when a parameterized cell is opened in OpenAccess, the Common Design Framework (CDF) data for the cell will be dumped to a file in the current directory. The file name is the cell name with a ``.cdf'' extension. This is for development/debugging.
