IBIS Modeling Utilities

• ibischk3 - Links to file directory:
  The official ibischk3 checks Version 1.1, 2.1 and 3.2 level IBIS files. (Use -ebd and -pkg flags for .ebd and .pkg files.) Contracted by the IBIS Open Forum, many vendors supported and contributed to its development.
• ibisinf
  Download an IBIS information and checking utility available from Zuken that provides more file information about components and models.
• ibis2spice
  Download an IBIS to Spice conversion utility from Intusoft. Feedback is requested. Intusoft will upload templates to work with all versions of Spice.
• ibischart
  An IBIS model display utility available from Mentor Graphics for IS and which shows all tables simultaneously and supports zooming into regions of any table.
• ibis_comp_gen
  Builds a properly formatted skeleton IBIS file for all components names, model names, and pin names encountered in your design. Included with purchase of ICX from Mentor Graphics.
• qd2ibis
  A Quad Design format to IBIS converter. Included with purchase of ICX from Mentor Graphics.
• s2ibis (Version 1.3) - Links to file directory:
  North Carolina State University provided the original s2ibis utility for automatic Spice model to IBIS Version 1.1 model conversion.
• s2ibis2 (Version 1.1) - Links to file directory:
  North Carolina State University provided the s2ibis2 utility for automatic Spice model to IBIS Version 2.1 model conversion. Also download the s2ibis2.fix.tar.Z file and compile a new executable to avoid a decimal digit accuracy problem. Cisco Systems has contributed a Linux version with the fix included.
• s2ibis2 for NT - Links to file directory:
  Download executables and documentation contributed by SiQual Corporation which had some accuracy enhancement for better waveform table generation for Windows 95, 98, NT and 2000 environments.
• s2ibis2 SpiTran Graphical User Interface - Links to file directory:
  Spice to IBIS Graphical User Interface kit written in JAVA 1.2 for any platform contributed by Cadence Design.
• s2iplt - Links to file directory:
  A program which plots *.ibs file tables. Written by North Carolina State University.
• spice2pkg
  A Spice to IBIS-like converter to model electrical characteristics of connectors in ICX IS_MultiBoard. Available with purchase of the ICX IS_MultiBoard product from Mentor Graphics.
• top2ebd
  A Quad Design topology file to EBD (Electrical Board Description) converter that also converts models to IBIS models. Available with purchase of ICX from Mentor Graphics.
