This file contains the details of the modifications made in the latest version of s2ibis3 (v1.0). 
---------------------------------------------------------------------------------

1)Correct the clamp subtraction algorithm for Pullup and Pulldown curves for enabled (tristate) drivers. 
The 3-stated buffer is swept through the same range as the driving buffer. 
The entire 3-stated data is subtracted from the entire driving data. 
This is done for both the Pullup and Pulldown curves.

2) Run s2ibis3 from a test directory with a separate installation directory.
s2ibis3 will find all the needed test files in a directory that does not need
the /java directory. The -root switch will tell the program where to find the
installation directory. This way all the simulation files could be stored for
each individual run without much effort.

3) Have an improved error reporting system. In the past versions, most errors
pointed, incorrectly, to an older version of java.

4)Implemented the [ExtSpiceCmd] keyword to add external spice setup command
as suggested by Hans-Gerhard Baumann.

5)Display the "VERSION" string in .spi files. - change made in s2iHeader.java


6)S2IBIS3 works with eldo by adding the switches
.OPTION COMPMOD
.OPTION COMPNET
.OPTION COMPAT
in your spice netlist.

7)Remove warning about no .msg file.
8)When simulators are hspice and eldo, does not tries to delete .msg file.
