 *  Our motivation in distributing this software freely is to encourage      *
 *  others to evaluate its effectiveness on a wider range of applications    *
 *  than we have resources to attempt, and to provide a foundation for       *
 *  further development of automatic synthesis techniques.                   *
 *                                                                           *
 *  We would very much appreciate learning about other's experiences with    *
 *  the system and suggestions for improvements.  Even more, we would        *
 *  appreciate contributions of two kinds: additional synthesis examples     *
 *  that can be added to the distribution, and enhancements to the synthesis *
 *  system.  Although we do not promise to distribute the examples or        *
 *  enhancements, we may do so if feasible.                                  *
 *                                                                           *

 *  The 3D synthesis system was designed in 1991-1992 by Kenneth Yun and     *
 *  David Dill of the Stanford University Computer Systems Laboratory.       *
 *  New features have been added steadily since then.                        *
 *  The 3D synthesis system makes use of the logic minimizer designed and    *
 *  implemented by Robert Fuhrer and Steven Nowick of Columbia University.   *
 *                                                                           *
 *  Financial support for the design and implementation of the 3D synthesis  *
 *  system has come from the Stanford Center for Integrated Systems          *
 *  and Semiconductor Research Corporation.                                  *
 *                                                                           *
 *  C.  Support, comments, feedback                                          *

 *  If you need help or have comments or suggestions regarding the 3D        *
 *  system, please send electronic mail to "kyy@paradise.ucsd.edu".          *
 *  We do not have the resources to provide commercial-quality support,      *
 *  but we may be able to help you.                                          *
