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.

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 Mit freundlichen Grüßen / Best regards / Cordiali saluti / ystävällisin terveisin Eckhard Lenski Nokia Siemens Networks GmbH & Co.

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.
