IBIS Open Forum

The IBIS Open Forum, an official subcommittee under SAE-ITC, is the industry organization responsible for the management of the IBIS specifications and standards including IBIS, IBIS-ISS, ICM, and Touchstone. The Open Forum conducts itself according to its Policies and Procedures document, the SAE-ITC Privacy Policy, and according to the AEROSPACE COUNCIL of the SAE Technical Standards Board Organization and Operating Procedures ®.

The Open Forum meets every three weeks by teleconference. Participation is open to all interested companies. Meeting minutes are available here.

Paid member organizations may cast votes regarding specification changes and approvals, financial matters, election of officers and other organizational issues involving the Open Forum. Dues for regular member organizations are US $900 per year. Academic institutions are eligible for reduced membership dues (50% of full rate). Membership dues go directly to maintain the organization's web site, pay for specification balloting, legal and bookkeeping services and the like as provided by our parent organization, SAE Industry Technologies Consortia (ITC).

The Open Forum also holds IBIS Summits several times per year around the world, to give our members an opportunity to meet face-to-face and exchange technical information and elect officers.

IBIS 7.1 and IBISCHK7

The IBIS Open Forum is responsible for the ibischk series of IBIS Golden Parsers to validate IBIS models developed according the the latest IBIS Version 7.1. The Golden Parser is a syntax checking program to aid the development and verification of IBIS data files. Executable code, compiled for a variety of operating systems, are available free of charge at ibischk7.

The Open Forum also makes the source code of the ibischk7 available through a paid license. Licenses are separate from Open Forum membership; member and non-member companies alike may purchase a parser license at the same cost. The current cost of a parser license in US $3000. A parser license entitles the purchaser to receive and use the source code in their own products. A license also entitles the purchaser to both the current parser code and all minor revisions within the same major revision of the specification. For example, current purchasers of the ibischk7 parser source code will receive all upgrades to support IBIS 7.1, 7.2 etc. up to but not including the IBIS 8.0 specification.

Parser license fees are used exclusively for development of parser source code upgrades. Parser code development is externally contracted by the Open Forum through an "open bid" process.

The IBISCHK7 SOURCE CODE LICENSE AGREEMENT is available on-line. If you are interested in purchasing a license, please contact the IBIS Open Forum Chair or any of the IBIS Officers for further instructions.

Touchstone 2.0 and TSCHK2

The IBIS Open Forum has introduced the Touchstone File Format Specification Version 2.0, which expands the defacto standard Touchstone (1.0) which deals with N-port parameters including S-parameters, and also Y-, Z-, G-, and H-parameters. The IBIS Open Forum has expanded the capabilites to include mixed-mode formatting and selectable reference impedances.

Licenses are separate from Open Forum membership; member and non-member companies alike may purchase a parser license at the same cost. The current cost of a parser license in US $1000. A parser license entitles the purchaser to receive and use the source code in their own products. A license also entitles the purchaser to both the current parser code and all minor revisions within the same major revision of the specification. For example, current purchasers of the tschk2 parser source code will receive all upgrades to support Touchstone 2.1, 2.2, etc. up to but not including the Touchstone 3.0 Specification.

The TSCHK2 SOURCE CODE LICENSE AGREEMENT is available on-line. If you are interested in purchasing a license, please contact the IBIS Open Forum Chair or any of the IBIS Officers for further instructions.
