| IBIS Interconnect Task Group |
The Interconnect Task Group exists to create, maintain, and promote multiple specifications related to modeling and representing measurement data for interconnects, including device packages, cable/connector assemblies, modular sub-systems, and printed circuit board (PCB) traces.
The Task Group began as the Connector Task Group, but a new name was applied after the group's work began to expand to several other advanced modeling topics related to interconnects.
The chair of the Task Group is Michael Mirmak (michael.mirmak@intel.com).

The Connector Task Group produced the IBIS Interconnect Modeling Specification, formerly the IBIS Connector Modeling Specification (ICM), which was released in 2005. This document can be viewed at the ICM page.
Since becoming the Interconnect Task Group, the team has focused on two major areas:
- IBIS ISS, the Interconnect SPICE Subcircuits specification - the current version is 1.0
- Touchstone - the current version is 2.1. While originally part of an industry software package with a long history, management of Touchstone as a data format was transferred to the IBIS Open Forum in the early 2000s.
These specifications are intended for use both independently of IBIS as well as for describing interconnects within IBIS structures, including for packaging, such as IBIS AMI, C Comp Model, EMD and IBIS Interconnect.
A parser for Touchstone is available at the TSCHK2 page.
The team is currently focused on technical changes to Touchstone, to become Touchstone 3.0. Approved and proposed changes to Touchstone can be viewed at the TSIRDs page. Working documents related to Touchstone revisions can be seen on the Presentation Archive.
The team will next turn to revisions to IBIS-ISS. Approved and proposed changes to IBIS-ISS can be viewed at the ISSIRDs page.Email discussion
