To All: The IBIS Open Forum is making available the official Touchstone Version 2.0 parser/checker (tschk2) for Windows (dos32), 32- and 64-bit Linux_redhat, Mac_x, and Sun_5 operating systems. It checks Touchstone files against the official Touchstone Specification approved by the IBIS Open Forum in April 2009: http://www.eda.org/pub/ibis/tschk2/ http://www.eda.org/pub/ibis/touchstone_ver2.0/ Thanks to Brian Andresen of Agilent Technologies (EEsof EDA) for developing tschk2. The utility detects and checks against a strict interpretation of the Touchstone 1.0 (original version but with unlimited number of ports) and Touchstone 2.0 files. Features include: - Checking of Touchstone 1.0 and 2.0 files against the official specifications. - Reporting Error and Warning numbers and messages - Automatic upgrading of Touchstone 1.0 files to Touchstone 2.0 (-canonical, -canonical-v2) - Automatically detecting the number of ports and number of frequencies and other information - Un-normalizing Y-/Z-/G-/H-parameters and effective noise resistance) - Downgrading, where practical, Touchstone 2.0 files to Touchstone 1.0 (-canonical-v1) - Normalizing Y-/Z-/G-/H-parameters and effective noise resistance) - Applying Touchstone 1.0 column formatting rules - Moving two-port data into the 21_12 order - [But not dealing with [Reference] or [Mixed-Mode Order] Version 2.0 selections in doing transformations] - Describing the content of Touchstone 1.0 and 2.0 data in an un-normalized real, imaginary format (-describe) The -help flag provides these Usage modes: tschk2 FILE Checks the file, sending error and warning information to stderr. tschk2 -canonical FILE Shortcut for -canonical-v2. tschk2 -canonical-v2 FILE Checks the file, sending error and warning information to stderr, and writes a valid file to stdout in Touchstone v2 format. tschk2 -canonical-v1 FILE Checks the file, sending error and warning information to stderr, and writes a valid file to stdout in Touchstone v1 format, if possible. tschk2 -describe FILE Checks the file, sending error and warning information to stderr, and writes a valid file to stdout in a long-form description. tschk2 -version Displays the version number. tschk2 -help Displays this help message. Source code licenses are available to developers for USD 1000. This allows commercial vendors to legally use (with minimal restrictions) the official parser source code externally in products and internally thoughout the company. The code is in C++ and is well documented. The package includes over 440 test cases for the official interpretation of Touchstone Version 1.0 and Version 2.0, and Python scripts to invoke the tests.
