Milpitas, Calif. – January 13, 2011 – GLOBALFOUNDRIES today
introduced the industry’s first 28nm silicon-validated signoff-ready
digital design flows
to help chip designers deliver the next
generation of power-sensitive mobile and consumer electronic devices.
Developed in collaboration with EDA/IP ecosystem leaders and based on
GLOBALFOUNDRIES’ 28nm Super Low Power (SLP) technology with Gate First
High-k Metal Gate (HKMG), the flows are precisely tuned to help
overcome the unique challenges of designing and manufacturing
integrated circuits at leading edge nodes.

The new signoff-ready flows were developed with recognition of the
need for silicon validation to ensure first-time-right silicon
success, setting a new standard for quality, scope, and relevance in
foundry flows. Customers can now produce signoff ready 28nm designs
using the industry’s most advanced set of synthesis, place and route,
sign-off, and DFM tools, tool scripts, and methodologies.

“Many of the world’s top IC designers are using our 28nm technology to
deliver tomorrow’s most innovative mobile and consumer devices,” said
Mojy Chian, senior vice president of design enablement at
GLOBALFOUNDRIES. “By collaborating closely with our partners in the
EDA/IP ecosystem to provide a comprehensive 28nm design platform, we
are giving customers confidence that their designs will be brought to
life smoothly and in time to meet their critical market requirements.”

Traditional foundry design flows have not taken into account the
growing interaction of design and manufacturing at advanced technology
nodes. GLOBALFOUNDRIES has addressed these issues by emphasizing early
collaborative development with providers of EDA software and IP to
validate design methodologies against real silicon. In addition to
tight integration with GLOBALFOUNDRIES’ signoff physical verification
solution, all flows leverage GLOBALFOUNDRIES’ heritage as a leader in
Design-for-Manufacturing (DFM) by supporting DRC+, the company’s
silicon-validated solution that goes beyond standard Design Rule
Checking (DRC) and uses two-dimensional shape-based pattern-matching
to enable up to a 100-fold speed improvement in identifying complex
manufacturing issues without sacrificing accuracy.

GLOBALFOUNDRIES and Cadence have jointly developed a complex 28nm-SLP
design that fully demonstrates Cadence’s portfolio of advanced silicon
implementation tools, including high-level synthesis, low power,
routing, DFM, and verification. The 9 mm2 multi-million gate design
is architected to highlight and showcase advanced 28nm chip
implementation techniques and to enable quantitative silicon
validation of power, performance, and area tradeoffs, as well as
robustness and yield. The design is being released to manufacturing
and is expected to be silicon validated in the first half of 2011.
The full design, implementation scripts, and a set of recommended
methodology white papers on 28nm routing and DFM will be available to
customers starting in Q1 of 2011.

GLOBALFOUNDRIES and Synopsys have collaborated to develop a 28nm-SLP
design flow based on the Synopsys Galaxy™ Implementation Platform,
together with a 28nm-SLP Foundry-Ready System technology plug-in for
the Lynx Design System. The silicon-proven design flow integrates the
GLOBALFOUNDRIES 28nm-SLP design rules with Synopsys’ latest EDA
technologies, including PrimeTime® advanced on-chip variation
analysis, IC Compiler’s DFM-optimized Zroute router and In-Design
physical verification, and IC Validator DRC and DRC+ pattern support.
The Lynx Foundry-Ready System adapts Lynx’s Galaxy Platform-enabled
production design flow to GLOBALFOUNDRIES’ technology and includes
guidelines and tool settings based on the latest 28nm silicon data to
help ensure the highest quality and the most robust designs. The Lynx
Foundry-Ready System addresses recommended routing rules,
on-chip-variation and advanced on-chip variation analysis, and DFM,
enabling a more efficient handoff with the foundry. Both the foundry
design flow and 28nm-SLP Lynx Foundry-Ready System are expected to be
available to customers starting in Q1 of 2011.

GLOBALFOUNDRIES and Mentor Graphics are developing a complete
reference flow based on the Olympus-SoC™ and Calibre® InRoute™
products. The Olympus-SoC router has been qualified for
GLOBALFOUNDRIES’ 28nm-SLP technology, providing support for both
advanced 28nm ground rules and recommended rules to implement DFM,
improved recipes for efficient routing, and support for manufacturing
scoring analysis (MAS).

GLOBALFOUNDRIES and Magma have worked to develop a 28nm-SLP
signoff-ready flow based on the Talus® Vortex IC implementation
platform. Talus Vortex is an ideal physical design environment for
engineers creating complex systems on a chip (SoCs) at all process
nodes and where performance and power management are crucial. It
dramatically improves productivity by allowing designers to implement
up to 1.5 million cells or more per day on large designs or blocks –
with crosstalk avoidance, advanced on-chip variation (AOCV) and
multi-mode multi-corner analysis enabled. Talus also performs advanced
low-power design analysis and optimization via an automated multi-Vdd
methodology. Talus has already been used by Magma’s and
GLOBALFOUNDRIES’ mutual customers to meet aggressive time, power and
performance targets.

GLOBALFOUNDRIES is jointly developing a 28nm-SLP signoff-ready flow
with Apache Design Solutions using RedHawk™ and Totem™ to provide
customers with a robust solution to meet their low power demands.
RedHawk is a production proven power signoff platform for large scale
SoCs including those with ultra-low power design techniques. Totem
offers power, noise, and reliability sign-off for analog/mixed-signal
designs. The suite of Apache’s products in the GLOBALFOUNDRIES’
sign-off flow enables designers to perform early prototyping, circuit
optimization, and full-chip sign-off.

A prerequisite in developing all of these advanced flows is rigorous
qualification of the digital routers. GLOBALFOUNDRIES has developed a
stringent set of requirements that digital routers from Cadence,
Synopsys, Mentor Graphics, and Magma must meet in order to be
qualified as signoff-ready. This includes meeting physical
verification signoff rules and recommended rules, run time and memory
footprints, as well as quality of results. The signoff-ready flows
and router qualifications are supported by a full suite of 28nm-SLP
Artisan advanced physical IP from ARM, including standard cells, power
management kit, memory compilers, and interface IP.

All of GLOBALFOUNDRIES’ 28nm technologies employ the Gate First
approach to HKMG, which is superior to other foundry 28nm technologies
in both scalability (performance, power, die size, design
compatibility) and manufacturability. The Gate First solution shares
the process flow, design flexibility, design elements and benefits of
all previous nodes based upon Poly SiON gates.

"Once again, Cadence has teamed with GLOBALFOUNDRIES to help our
mutual customers tackle their toughest advanced-node challenges," said
John Bruggeman II, senior vice president and chief marketing officer
of Cadence. "Our Silicon Realization technologies, particularly the
Encounter Digital Implementation (EDI) System, enabled us to play a
leading role on the 28nm High-K Metal Gate Signoff-Ready Digital
Design Flow. This end-to-end digital flow leverages unified,
silicon-proven 28nm routing intent, DFM abstraction and built-in
signoff capabilities to deliver predictable silicon convergence. In
addition, EDI System’s in-design DRC+ leverages signoff-quality
pattern matching technology, providing customers with
GLOBALFOUNDRIES-certified DRC+ fixing, which is over 100 times faster
than traditional flows."

“Our early collaboration on process, design and manufacturing has
enabled GLOBALFOUNDRIES and Synopsys to deliver a comprehensive
front-to-back production-proven 28nm design solution based on the
Synopsys Lynx Design System,” said John Chilton, senior vice president
of marketing and strategic development at Synopsys. “The Galaxy
Implementation Platform’s advanced design and physical verification
technologies, along with the pre-validated 28nm SLP Lynx Foundry-Ready
System, enables leading-edge SoC design teams to deliver their
next-generation power- smart mobile and consumer electronic devices
more efficiently and with lower integration risk and cost.”

“Achieving 28nm signoff-ready flows is a continuation of the long-term
collaboration and mutual investment between GLOBALFOUNDRIES and
Mentor,” said Joseph Sawicki, vice president and general manager of
Mentor’s design to silicon division. “The integration of Olympus,
Calibre and GLOBALFOUNDRIES technology into a seamless flow, including
consideration and optimization for advanced DFM effects, ensures
signoff-ready results. This solution helps mutual customers fully
leverage 28nm process capabilities, yet still maintain or reduce
design cycle times.”

“Supporting the ever-increasing performance, time-to-market and power
minimization requirements of the 28-nm ICs used in today’s tablets,
smartphones and networking and embedded devices requires advanced
design and manufacturing technology,” said Premal Buch, general
manager of Magma’s Design Implementation Business Unit. “The
combination of GLOBALFOUNDRIES 28nm-SLP process technology and Talus
Vortex provides mutual customers with extremely fast throughput for
low-power designs at the 28-nm node.”

“Apache Design Solutions’ focus is on delivering products that address
the critical design challenges of power, noise, and reliability. The
company’s industry proven sign-off solutions for digital and custom IC
power supply noise, electro-migration (EM), and electro-static
discharge (ESD) have enabled many customers to predict and manage
power related issues in their designs,” said Dian Yang, senior vice
president and general manager of Apache. “Apache’s collaboration with
GLOBALFOUNDRIES on the 28nm-SLP sign-off flow will further ensure our
mutual customers to meet low power demands and achieve silicon
success.”

“The ARM Artisan physical IP platform offers designers a wide range of
implementation options to achieve their low power requirements and
processor performance goals,” said Simon Segars, ARM, executive vice
president and general manager, Physical IP Division. “Qualifying EDA
technology with Artisan physical IP and tuning the IP for
GLOBALFOUNDRIES’ manufacturing process is an important element of
assuring these platforms support the diverse SoC implementation flows
used across the fabless semiconductor industry.”
