Not sure if this has come up in this thread, but Rising and Falling table
interpretation CHANGED.  While IBIS is generally back-compatible (except for
1.1), this change was made to clarify an original intent.
 
In 3.2, the Rising and Falling tables could start with different reference
times.  Example: Rising tables at 0nsec and Falling at 50nsec.
 
In 4.x, both Rising and Falling tables have the SAME reference time
(normally 0nsec).  This means that in the example, Rising transitions would
start immediately with the trigger, while Falling transitions would have a
50nsec delay before the output transition could begin.
 
Best regards,
Lynne

Hello Chetana,
 
what might help you, is a presentation from Bob Ross 
 
 
http://www.vhdl.org/pub/ibis/summits/sep07b/ross_4_2_tree.txt
 
 
where you can see all ibis keywords/parameters  and an information ,with
which ibis version they appeared
 
 
 
Anyhow, you have to be aware of  that just refering to an ibis version might
not help you, because some ibis parameters are optional.
 
E.G. models with rising falling waveforms 
 
this keyword appeared with ibis version 2.1  but is optional 
 
 
models with over-under-shoot 
 
 the corresponding keyword  [Model Spec] appeared  with ibis version 3.2, 
but is not required.
 
 
So I think, you might asked your customer directly, which
parameters/keywords he needs for his ibis model
 
 
regards
Eckhard

Betreff: Re: [IBIS] How do I upgrade the IBIS version ?



Hi,



I am not aware if installing  S2IBIS3 will enable me to generate the 3.2
version IBIS models. Is that so ? 


Currently we use a script to generate IBIS models which are compliant with
2.0 format. 


There is a request from one of the customers that they want 3.2 format IBIS
models. 


I would like to know how do I upgrade to 3.2 version ? 


Is there a document which would help me do it ? 



Best Regards 


Chetana

Re: [IBIS] How do I upgrade the IBIS version ?	
	 	

Hi,

If you are asking on to how to install the S2IBIS3 too then plz refer 
the below

1. Download the S2IBIS3 source code from the link below.
   http://www.ece.ncsu.edu/erl/ibis/s2ibis3/s2ibis3.htm
2. Make sure JAVA is installed in the Linux/Unix system. Please check 
the specific version below.
3. Follow the procedure given below to setup the tool.
  Make sure u simulate all the files in order.
4. First compiling use JAVAC file.java
5. Also attached is the read me file for further help.

*---------------------------------------------------------------------------
--------------------------------------------------------------*
*Requirements: *   To run s2ibis3, Java2, version 1.4.0 must be installed.
       A minimum of Java 2 Runtime Environment(JRE), version 1.4.x.
       must be installed to be able to run s2ibis3. Users could also
       install Java 2 Standard Development Kit (SDK) version 1.4.x.
       This is preferred over the JRE as the user could modify a java
       file and recompile the code. Java JRE or SDK could be downloaded
       free from http://java.sun.com
       s2ibis3 assumes that the spice engines are set in the path
       variables and ready for use.
      
       This version has been tested on HSpice ver 2001.2

*Compiling the Code :* If the code has to be compiled, it must be 
compiled in the
            following order -s2iHeader.java, s2iutil.java,
            s2ispice.java, s2ianalyz.java, s2iParser.java and
            s2ibis3.java. If this order is not followed, compilation
            error could be experienced.
      
*Running S2ibis3 *   : sun/linux/unix
           -To run s2ibis3, type the following on the command line:
           % s2ibis3.csh -s2ibis3 buffer.s2i
           where buffer.s2i is the s2i command file as discussed in
           the s2ibis3.txt
           -If there is a 'permission denied' error when running the
           .csh file, change permissions by doing
           % chmod 744 s2ibis3.csh
           -If it is desired, s2ibis3 could be run from a different
           directory from the installation directory by using the
           '-root' switch with s2ibis3.csh as this example suggest:
           % s2ibis3 -root ../../s2i_install_dir -s2ibis3 buffer.s2i

This README file describes the v1.1 distribution of s2ibis3.


This directory contains the s2ibis3 Java application. 

This utilitiy has been tested for Sun Solaris (5.7), Linux 2.4.18 and
Windows XP.

To install S2IBIS3, simply unpack the zip file. This distribution contains:

README this file.
s2ibis3.csh Run this file to execute s2ibis3 for linux or unix
s2ibis3.bat Run this file to execute s2ibis3 for Windows
s2ibis3.txt An explanation of the command structure for the s2i file and the

key features and differences of s2ibis3 as compared with s2ibis2.
curves.txt An explaination of how the various curves are obtained in
s2ibis3.

modification_v1.1.txt An explanation of the changes made to s2ibis3 in the
latest revision (v1.1).

java directory with java source code and class files.
The source code can be modified and recompiled using 
Java sdk 1.4.0.
The source code consists of 
1)s2iHeader.java
2)s2iutil.java 
3)s2ispice.java
4)s2ianalyz.java
5)s2iParser.java
6)s2ibis3.java

example         example directory with 4 sub-dirs ex1, ex2, ex3 and ex4.

ex1 Directory with a sample buffer.s2i file along with a buffer.ibs
file. it also has the buffer.sp, spectre.mod and hspice.mod files 
to be able to run the example properly.

ex2 Repeat of ex1 run with Hspice with a slightly better model.

ex3 Directory with similar files as above and an extra netlist file
that has the netlist of the parallel_mosfet. This is needed for
demonstrating the working of the [Series MOSFET] keyword.

ex4 Directory with tri-state drivers show how multiple Vdd's can be
used using the [Pin Map] keyword. This example uses HSpice.

Requirements: To run s2ibis3, Java2, version 1.4.0 must be installed. 
A minimum of Java 2 Runtime Environment(JRE), version 1.4.x.

s2ibis3 assumes that the spice engines are set in the path
variables and ready for use.

This version has been tested on HSpice ver 2001.2 

Compiling the Code : If the code has to be compiled, it must be compiled in
the
     following order -s2iHeader.java, s2iutil.java,
     s2ispice.java, s2ianalyz.java, s2iParser.java and

     error could be experienced.

Running S2ibis3 : sun/linux/unix
-To run s2ibis3, type the following on the command line:
% s2ibis3.csh -s2ibis3 buffer.s2i
where buffer.s2i is the s2i command file as discussed in
the s2ibis3.txt
-If there is a 'permission denied' error when running the
.csh file, change permissions by doing 
% chmod 744 s2ibis3.csh
-If it is desired, s2ibis3 could be run from a different
directory from the installation directory by using the
'-root' switch with s2ibis3.csh as this example suggest:
% s2ibis3 -root ../../s2i_install_dir -s2ibis3 buffer.s2i


  windows
    -most of the instruction for unix apply for windows users as well.
-To run s2ibis3, type the following on the command prompt:
% s2ibis3.bat -s2ibis3 buffer.s2i
-If the path variables are not set for java and the spice engines, 
read instructions at http://java.sun.com/j2se/1.4.2/install-windows.html
on how to set path variables for windows. s2ibis3 would not run if paths
have
not been set properly.
[note] % is not needed to be inserted in the command line.
