Mentor Graphics and X-FAB Provide New Production-Proven Design Kits for Mentor's Mixed-Signal IC Design Flow

Erfurt, Germany, April 29, 2004.

Mentor GraphicsCorporation (Nasdaq: MENT) and X-FAB Semiconductor Foundries AG todayannounced the availability of the first three in a series of technology design kits(TDKs) supporting X-FAB’s CMOS process technologies. The three kits, the XC06,XC035 and XC035 LV, have been validated and are available now for use with theMentor Graphics analog/mixed-signal (AMS) integrated circuit (IC) design flow.These open-source TDKs reduce the time required to set up design environments,cutting weeks off design time, increasing productivity, and ultimately shorteningtime-to-market.

X-FAB’s AMS CMOS technologies XC06, XC035 and XC035LV are set up in amodular way, offering maximum flexibility and cost-effectiveness while enablingdesigners to select only those process options that match their application needs.XC06 is a two or three metal layer 0.6μm 5.0V CMOS process with 17 modularoptions, including medium and high voltage MOS transistors, passive elements andembedded EEPROM and Flash blocks. XC035 and XC035LV are three or four metallayer 0.35μm 3.3V CMOS processes with optional double poly and high resistivitymodules. XC035 also offers 5V capability with a single or double gate option, whileXC035LV, which adds a non-volatile EEPROM module and a Schottky diodemodule, is capable of operating voltages down to 1.0V.

Customer-Proven Technology
Apogee Technology Inc. recently taped out a mixed-signal chip using the XC06 kit.
Apogee, a developer of high-power audio amplification chips, designed the IC
entirely in-house using the complete Mentor IC design flow.

"We needed a cost-effective 5V analog process that would give us optimum die size.
XC06 allowed us to effectively utilize silicon, meet our die size constraints, and
control the die price," said Justin Fisher, group leader of analog design at Apogee.
"We chose the Mentor IC design flow due to its superior performance on simulation
and design rule checking. Having the XC06 TDK helped us realize dramatic time
savings by leveraging its well-coded device generators. Together with IC Station’s
integrated automatic routing tools, these device generators reduced custom block
layout time from several days down to a few hours."

The new design kits include X-FAB-supported Eldo™ analog simulation models and
Calibre® design rule checking (DRC), layout vs. schematic (LVS) and extraction
technology files. They also include schematic symbols for the Design Architect®-IC
tool, programmable device generators for schematic-driven layout with IC Station,
process definition files, and all other configuration files necessary to effectively
utilize the Mentor Graphics® complete AMS IC design flow.

"As demand for Mentor’s mixed-signal IC flow increases, we have intensified our
support for ready-to-use design kits that can accelerate design starts using our flow,"
said Jue-Hsien Chern, vice president and general manager, deep submicron (DSM)
division, Mentor Graphics. "We’re pleased to be collaborating with X-FAB on these
TDKs. X-FAB’s CMOS processes are ideal for our customers designing highprecision,
low-power mixed-signal circuits for consumer, automotive and telecommunication products."

These X-FAB kits are unique in that they are designed to fully support the digital
portion of the Mentor AMS design flow. They include libraries with I/Os for pad and
core limited designs, various digital libraries for high-performance, high-density, lowpower, and low-noise applications, as well as a variety of tested and qualified analog intellectual property (IP) blocks. The XC06 TDK contains standard cell and pad cell libraries with symbols for the Design Architect-IC tool, simulation models for the
ModelSim® tool and layout representations for place and route with the AutoCells™
tool; similar libraries for XC035 and XC035LV TDKs will be available by mid-2004.

"The new Mentor design kits for XC06, XC035 and XC035LV offer a complete set of
libraries, views and technology files that leverage Mentor’s mixed-signal design
capabilities," said Jens Kosch, CTO, X-FAB Group. "These TDKs can help kick-start
a design from HDL all the way to GDSII for the leading-edge processes at X-FAB
Semiconductor Foundries AG."

The XC06, XC035 and XC035 LV design kits have been qualified by both X-FABand Mentor and are available immediately 24/7 through X-FAB's X-TIC online accesspoint.
