S2IBIS3 really generates only I/V curves and waveforms. All other content is provided by you. IBIS 3.1 added [Submodel] and 3.2 added golden waveforms, both of which S2IBIS3 theoretically could, but does not, produce. If the 3.x content would would like to have is not one of these, S2IBIS3 would only pass through the data you give it anyway.

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 ?

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 *----------------------------------------------------------------------- ------------------------------------------------------------------------ -* Regards, Shrikant GK NSC, Bangalore.

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.
