The command language for running s2ibis3 conforms to the command structure of s2ibis2 with the exception of the [Summarize] keyword - which has not been implemented.
A key feature that has been implemented in s2ibis3 is the capability of handling convergence issues with Hspice. If non-convergence is detected, the user is asked to enter new sweep values for the beginning and the end of the sweep. Spice is again run with the new values and if again faces non-convergence, comes back and asks for new values again. This procedure is repeated until spice converges or user aborts. Convergence help is only implemented for Hspice. Convergence specific information for other simulators are welcome so that convergence handling could be extended to other engines.
The language used is Java, as such, a single version of the utility should be compatible with the various platforms available. S2IBIS3 has been tested on solaris 5.7 (HSpice and Spectre) and win XP(HSpice). Also – this version is backward compatible to older versions of ibis (ver 1 and 2.1).
This is a Java program - as such java (v 1.4.1 or better) needs to be installed on the user machine. More instructions are provided in the README file.
In this release, ibis v3.2 specific keywords such as [series MOSFET], [series pin mapping] and [series switch groups] and other related keywords are supported.
Having trouble installing S2IBIS3? There is an FAQ here to help you with basic questions regarding setup and other issues.

Syntax Highlighting for NEdit for s2ibis3 command file (.s2i)
For easier use and better viewing, NEdit users might want to use syntax highlighting for their .s2i files. Instructions to install highlighting is as follows. More instructions are in the s2i.pats file (open with wordpad, notepad or any common editor).
Download s2i.pats and load this pattern by starting nedit with:
% nedit -import s2i.pats
check that the patterns were loaded correctly, and choose Save Defaults from the Preferences menu. The new patterns will now be incorporated into your own .nedit file, so the next time you start NEdit, you will no longer need to use -import.
-Support to ver3.2 keywords such as series MOSFET and other related keywords added.
