Cadence Completes Acquisition of Simplex Solutions
Electronic Design Leader Fields World's Best Technology Line-Up
for 0.13-Micron-and-Beyond


SAN JOSE, Calif.--(BUSINESS WIRE)--June 27, 2002--Cadence Design Systems, Inc.
(NYSE:CDN - News), the world's leading supplier of electronic design products
and services, today announced the completion of its acquisition of Simplex
Solutions, Inc. (Nasdaq:SPLX - News), a Sunnyvale, Calif.-based company that
provides software and services for the design and verification of chips.

Cadence reached a definitive agreement to acquire Simplex on April 24, 2002.
This acquisition is a key milestone in the Cadence strategy to deliver
manufacturing-aware design flows that enable customers to achieve 1st Silicon
Success(R) with the most advanced manufacturing technologies. It also advances
the Cadence(R) Design Chain Initiative aimed at strengthening development
relationships throughout the electronics industry.

"The Simplex acquisition is the latest in a series of bold moves Cadence has
made over the past 18 months to consolidate its technology leadership for chip
design at 0.13-micron and beyond," said Ray Bingham, president and CEO of
Cadence. "We are transforming Cadence by strategically leveraging acquired
technology and management resources, our own focus on innovation for our
customers, and through our commitment to interoperability through the OpenAccess
database. With the addition of CadMOS, Silicon Perspective, Plato Design Systems
and, now Simplex, to the Cadence team, we've put together the world's best
line-up for leading-edge design."

At Cadence, Penny Herscher, chairman and CEO of Simplex, has assumed the new
position of executive vice president and chief marketing officer, reporting to
Ray Bingham. She will be responsible for strategy, marketing and the Cadence
Design Foundry(R) business unit announced today.

"The entire Simplex team is excited to be part of the new Cadence," said
Herscher. "With the combined companies' complementary and synergistic
technologies, Cadence will address our customers' rigorous performance and
manufacturability requirements at 0.13 micron and beyond."

Aki Fujimura, Simplex's president and COO, will lead the Cadence design for
manufacturing (DFM) effort as corporate vice president and general manager of
the Cadence DFM business unit, reporting to Lavi Lev, executive vice president
of Cadence IC Solutions. Fujimura will integrate DFM technologies -- including
Simplex's technologies -- into all Cadence solutions, and will continue to lead
the development of the X Architecture -- a very promising next-generation
technology for IC implementation. Steve Teig, Simplex's CTO, will take on the
newly created position of chief scientist, responsible for future Cadence
technology. Teig also joins the office of the CTO at Cadence and will report
directly to Ray Bingham. Dave DeMaria, former Cadence senior vice president of
worldwide marketing, has been promoted to executive vice president of Cadence
Systems Solutions. He will continue to report to Ray Bingham.




The physics challenges at 0.13-micron and beyond demand a new generation of
design technology solutions. To be successful, designers need tools that can
easily interoperate, and support hierarchical design methods and rapid
prototyping. These tools must also take into account critical, deep submicron
effects, such as signal integrity, voltage (IR) drop, electromigration and
substrate noise.

Cadence has had exclusive distribution rights for Fire & Ice(R) QX, Simplex's
leading 3D interconnect modeling and extraction tool, since January 2002. A
roadmap for the incorporation of Simplex's other products is currently under
development. This will include: VoltageStorm(TM) SoC, Simplex's flagship power
grid verification product, ElectronStorm(TM), for electromigration analysis,
SignalStorm(TM) SoC, for digital signal integrity delay calculation and library
characterization, and SubstrateStorm(TM), for substrate noise analysis.
