Silvaco and Si2 Release Unique, Free 15nm Open-Source Digital Cell Library

Sponsored by Businesswire

Silvaco Inc., a leading supplier of EDA software and design IP, today
announced that it is providing an open-source, 15nm standard-cell
library to Silicon Integration Initiative, an electronic design
automation software research and development joint venture. The library
is available to Si2 members and universities at no fee under the
Apache-2.0 open source license agreement.

Silvaco, through its acquisition of Nangate Inc., previously provided a
45nm open source cell library to Si2 under similar terms. This new
library aligns with the current generation of silicon process nodes and
is based on the FreePDK15 process design kit from NC State University.
This PDK does not contain proprietary or sensitive data that would
prohibit free sharing of a library built with it.

The new Silvaco cell library is free for non-commercial purposes and is
particularly suited to research programs and standards development
organizations that have previously had free access only to libraries
with much older process technologies. The Predictive Technology Model
from Arizona State University was used in conjunction with the PDK to
characterize the 15nm standard-cell library.

“Silvaco is active in several Si2 initiatives such as the Compact Model
Coalition and OpenAccess Coalition,” said Jens Michelsen, business
development director at Silvaco. “With Cello™, our solution for digital
cell library creation and optimization, we have a unique platform where
the creation and maintenance of standard-cell libraries at 15nm and
below becomes relatively effortless compared to other industry
methodologies. We’re pleased to contribute this missing element of the
flow development puzzle,” he concluded.

“This new contribution from Silvaco is a major step in filling a void
that has existed for over 10 years. This 15nm library will serve
academic researchers who are developing EDA algorithms targeted for our
newest technology nodes. This effort is a classic example of successful
cooperation between Si2 and industry. Having the continued support of
Silvaco and its automated library creation solution ensures that our
member’s collaborative efforts are kept current with ever-changing
process developments,” said John Ellis, president and CEO at Si2.

“We’re very excited to see that Silvaco independently chose to
contribute new material to the FreePDK15 effort. We hope others in the
user community follow their lead,” said Rhett Davis, professor of
computer and electrical engineering at NC State University, and
principal investigator of the FreePDK15 project.
