Library Directories

The stock library files that ship with Twin Builder are stored under the \syslib directory. These libraries are intended to be read-only and cannot be modified.

In addition to the system libraries, Twin Builder recognizes two user-configurable library structures: the User Library and the Personal Library. These are used to add foundry support, user-defined models, and any custom or proprietary sets of components or simulation models. Customarily, userlib is a network repository for proprietary or corporate definitions available to all seats in an enterprise. PersonalLib contains project- and circuit-specific libraries as needed by individual designs.

A root library directory is set up at installation. If none is specified, the default is the root Twin Builder directory.
