Tower Semiconductor adopts Legend's
CharFlo-Memory!™ for quality assurance of commercially available
SANTA CLARA, Calif., --December 15, 2003 - Legend Design
Technology, Inc. today announced that semiconductor foundry Tower
Semiconductor (NASDAQ: TSEM; TASE: TSEM) has adopted CharFlo-Memory!
to implement a quality assurance (QA) methodology for commercially
available memory compilers. Based upon layout-extracted circuit data
with resistors and capacitors, Legend's CharFlo-Memory! toolset has
the capacity to generate accurate on-chip memory instance models at
any PVT (process, voltage and temperature) corner. The results
enable Tower to offer its clients the highest quality product
"System-on-chip (SoC) designs are becoming increasingly memory
dominant as silicon technology rapidly moves to deep sub-micron and
nanometer levels. Tower Semiconductor has put in place a memory
quality assurance (QA) flow that minimizes the growing gap between
the foundry and IP provider, and enables our customers to achieve
time-to-market goals for their SOC designs. We have successfully
used Legend tools to QA our wide portfolio of memory compilers from
leading IP vendors. Tower Semiconductor uses Legend's memory
characterization tool, CharFlo-Memory!, to efficiently produce
memory models that reflect the reality of the silicon. We are
dedicated to the overall quality of our design services and the
means to achieve the highest levels of customer satisfaction," said
Sergio Kusevitzky, vice president of design services and IP at Tower
"For the 'what-if' analysis on any PVT (process, voltage and
temperature) corner, Legend's CharFlo-Memory! has automated the
characterization task and accomplished it accurately and
efficiently. Tower Semiconductor now has the means to easily verify
the impact that a process change might have on memory IP function.
In addition, Legend's high-accuracy circuit simulator MSIM, which
is seamlessly integrated with CharFlo-Memory!, has provided
excellent performance and results," added Kusevitzky.
"Quality and reliability of embedded memory is essential for
silicon success of deep-submicron and nanometer SOC designs," said
You-Pang Wei, president and chief executive officer of Legend Design
Technology. "With the adoption of Legend's Charflo-Memory!, Tower
has acquired the leading-edge solution for memory IP quality
assurance and verification. We're pleased to be working closely with
Tower in meeting their needs for supporting their clients'
state-of-the-art SOC designs."
About Legend Design Technology, Inc.
Technology, Inc. is a leading provider of characterization and
simulation software for semiconductor Intellectual Property (IP) in
SoC designs. With an emphasis on productivity and value, Legend's
CharFlo-Memory! toolset which includes MSL, SpiceCut, MemChar and
MSIM, efficiently and accurately automate the time consuming and
error prone processes associated with characterization. SpiceCut
automatically builds critical-path circuits to reduce simulation
time for characterization, especially from post-layout extracted
circuits with resistors and capacitors. MemChar automatically
characterizes the memories and generates the 'true' timing and power
models. MSL automates memory characterization with customized setup
of '.Lib-in and .Lib out'. MSIM is a highly accurate
characterization-oriented circuit simulator with post-layout RC
reduction capacity. For more information, visit http://www.LegendDesign.com
