SAN JOSE, Calif., and HSINCHU, Taiwan, Sept. 20, 2007 - Magma Design Automation Inc. (Nasdaq: LAVA), a provider of chip design solutions, and UMC (NYSE: UMC), a leading global semiconductor foundry, today announced a broad physical verification and design for manufacturability (DFM) solution for 65-nanometer (nm) designs. The two companies completed joint qualification of Magma's Quartz^TM DRC, Quartz LVS and Quartz DFM for UMC's advanced processes and development of foundry-validated runsets and models that support the flow, which is tuned to detect design problems so they are corrected quickly. With the software, runsets and models, designers can accelerate time to market and improve manufacturability of chips targeted for UMC's advanced 65-nm process technology.

Quartz DRC and Quartz LVS are the industry's first fully scalable design rule checking (DRC) and layout-vs.-schematic (LVS) products. Leveraging a unique architecture and advanced modeling capabilities, this revolutionary physical verification solution allows affordable, massively distributed processing. With this technology and the right number of processors, virtually any design can be physically verified in less than two hours. Quartz DFM allows designers to analyze and characterize the timing and power impact due to sources of manufacturing variability, such as lithography and CMP. With this, designers can reduce the guard-banding required by traditional design flows, allowing significant gains in timing and power performance.

"UMC continually works to provide its customers with design and manufacturing solutions that help ensure silicon success. We believe Magma's physical verification software provides significant turnaround time advantages to our mutual customers," said Ken Liou, director of the Design Support division at UMC. "The qualification of Quartz DRC, Quartz LVS and Quartz DFM for our 65-nm process and our ongoing collaboration with Magma demonstrates our commitment to helping our customers address complex system-on-chip design challenges and shorten their time to market."

"IC designers need fast, reliable physical verification to help minimize the cost of developing advanced chips," said John Lee, general manager of Magma's Physical Verification Business Unit. "We pleased to be partnering with UMC to make it easier for more customers to leverage advanced process technologies to meet their most challenging design and schedule requirements."

Magma's software for designing integrated circuits (ICs) is used to create complex, high-performance chips required in cellular telephones, electronic games, WiFi, MP3 players, DVD/digital video, networking, automotive electronics and other electronic applications. Magma's EDA software for IC implementation, analysis, physical verification, circuit simulation and characterization is recognized as embodying the best in semiconductor technology, enabling the world's top chip companies to "Design Ahead of the Curve^TM while reducing design time and costs. Magma is headquartered in San Jose, Calif., with offices around the world. Magma's stock trades on Nasdaq under the ticker symbol LAVA. Visit Magma Design Automation on the Web at www.magma-da.com.
