IBIS Community,

I'm pleased to announce that IBIS Version 7.1<https://ibis.org/ver7.1/> was
approved unanimously in a vote of the IBIS Open Forum membership during the
December 10, 2021 IBIS Open Forum teleconference.

IBIS models are used for signal and power integrity analysis and are widely
available for digital ICs that interface to other digital ICs.  For an overview
of some of the new features in IBIS 7.1 see Expectations for IBIS
7.1<https://ibis.org/summits/nov21b/wolff2.pdf>, presented by Randy Wolff
(co-authored by Michael Mirmak) at the 2021 Virtual Asian IBIS Summit - China
meeting.

IC and module developers will now be able to supply I/O buffer capacitance and
multi-die package and module interconnect models using Touchstone and IBIS-ISS
(IBIS Interconnect SPICE Subcircuits).  Several enhancements to the IBIS
Algorithmic Modeling Interface (IBIS-AMI) improve modeling of equalization
found in the latest high-speed DDRx interfaces.  The IBIS-AMI "back-channel"
link training protocol is enhanced to add support for statistical-based
optimization of buffer equalization settings.  Another new feature adds support
for a simplified On-die Power Distribution Network (PDN) model. The new version
includes other technical and editorial improvements offering a significant
upgrade to IBIS version 7.0.

This is the first time that IBIS has developed our syntax checking software,
IBISCHK, in parallel with the specification editorial and approval process. The
software will be made available nearly simultaneously with the release of IBIS
version 7.1, aiding model developers and EDA tools to support IBIS version 7.1
compliant models more quickly. This concurrent development process improved the
quality of the new Electrical Module Description (EMD) syntax, a highly
anticipated interconnect modeling feature.

Many thanks to all who contributed to IBIS 7.1!  Happy Holidays.
