Directly Import Liberty File

Previously if you had a Synopsys Liberty File (.lib file) and wanted to import it into the Verdi™ Automated Debug System as the symbol library, you had to use the syn2SymDB utility to pre-compile the file into Novas symbol library first and then it could be imported into the Verdi system. Starting from the Novas 2010.07 release version, the ability to directly import liberty files is provided. With this capability you can directly import the Synopsys Liberty File from the GUI or from the command line when invoking the Verdi system.

There are two methods for importing the liberty file directly: from the GUI mode or from the command line. To import the file in GUI mode, invoke the Tools > Preferences command to open the Preferences form. Go to the Schematics > Symbol Library page, and specify the library file name and path in the Symbol Library Name and Symbol Library Paths fields, multiple names and paths are allowed in these fields. Power related information can also be imported by turning on the Import Power Symbol Information option in this form. See the figure below for an example.

To import the liberty file from the command line, set the name and path of the liberty file through the NOVAS_LIBS and NOVAS_LIBPATHS environment variables. An additional option, –powerSymbol, will be required to import the power information when invoking the Verdi system. The following figures show the difference between importing with and without power information.
