OSCI Completes First Analog/Mixed-Signal Standard for SystemC-based Design

DATE CONFERENCE – The Open SystemC Initiative
(OSCI), an independent non-profit organization dedicated to
supporting and advancing SystemC as an
industry-standard language for electronic system-level (ESL)
design, today released the SystemC Analog/Mixed-signal (AMS) extensions
language standard, AMS 1.0. The AMS 1.0 standard is the first
modeling language targeting system-level design and verification
to describe analog/mixed-signal behavior as natural extension to
existing SystemC-based design methodologies.

Designed for use with IEEE Std. 1666-2005, the
AMS language standardizes new class libraries, layered on top of
the SystemC standard, featuring specialized AMS system-level
design and modeling methods. The AMS language reference manual
(LRM) introduces new execution semantics for efficient simulation
of discrete- and continuous-time behavior, and incorporates
updates from the public review conducted in early 2009.

The AMS 1.0
standard is available for download under open-source license at systemc website.
The standard includes the requirements specifications, AMS
language reference manual (LRM), and a user’s guide, a
comprehensive manual explaining all fundamentals of the AMS
language standard and how to use the extensive set of features for
AMS behavioral modeling at the system-level.

“The AMS
extensions demonstrate how SystemC further advances with the
collaborative effort of semiconductor industry, universities and
research institutes,” said Eric Lish, OSCI Chairman. “I am delighted
that OSCI is in the center of this standardization effort, driving
these innovative ESL design methodologies.”

standard was developed by the OSCI AMS working group, with the
objective to define a true system-level modeling language as an
extension to SystemC. The new class definitions defined by the SystemC
AMS extensions are essential to describe AMS systems at different
levels of abstraction.

“The SystemC AMS extensions have evolved
significantly with the availability of the LRM and user’s guide
today,” said Martin Barnasconi, Chairman of OSCI’s AMS working
group. “I am very pleased with this achievement, and we look
forward to the widespread use and adoption of this AMS standard.”

The AMS working group members will continue to promote SystemC and
the AMS extensions, and will be providing periodic updates at
many workshops, tutorials, and conferences over the course of this
