Technology File Path Definitions

There are four search paths that may be specified. In each case, the path specification consists of a keyword, followed by the path. The format of the path is described in section 2.6 detailing the Xic search paths.

In the path defaults below, if the XT_PREFIX environment variable is defined, its value will replace ``/usr/local''.

Path path
The Path keyword specifies the path to design data files: native cell, archive, and library files. The current directory ``.'' should generally be listed first in this path. The design data path can also be set in the environment with the XIC_SYM_PATH variable. A specification in the technology file will override a specification in the environment.
Default: ( . )

LibPath path
The LibPath keyword specifies the path to the startup files. The startup files include the device library (default name device.lib), and the model library (default name model.lib). This path can also be set with the environment variable XIC_LIB_PATH, and a specification in the technology file will override an environment specification. Unlike other search paths, the current directory is always checked first when looking for files in this path, as if '.' was the first component.
Default: ( . /usr/local/xictools/xic/startup )

HlpPath path
The HlpPath lists directories containing database files for the help system. These files have names with suffix .hlp, and it is possible for users to create customized help files for their own purposes (the format is described in C.3). The help path can also be specified with the environment variable XIC_HLP_PATH, which will be overridden by a specification in the technology file.
Default: ( /usr/local/xictools/xic/help )

ScriptPath path
The ScriptPath contains directories where Xic searches for user generated command scripts. The script files have names with suffix ``.scr'', except for the library script which is named ``library''. This path can also be set with the environment variable XIC_SCR_PATH, which will be overridden by a specification in the technology file.
Default:( /usr/local/xictools/xic/scripts ).

Note that the XIC_LIB_PATH variable can be used to define the location of the technology file, and then redefined in the technology file to provide alternate locations for the device and model library files.

The path keywords, and all other keywords, are interpreted without case sensitivity when the technology file is read.
