Lattice Semiconductor and Synplicity Extend Partnership

Lattice Selects Synplicity as its Exclusive Logic Synthesis Solutions Provider

HILLSBORO, OR - April 21, 2008 - Synplicity, Inc. (NASDAQ: SYNP), a leading supplier of innovative IC design and verification solutions, and Lattice Semiconductor (NASDAQ: LSCC), a leading supplier of Field Programmable Gate Arrays (FPGAs), today announced an expansion to the companies’ existing OEM agreement. Under the terms of the new agreement, Synplicity will be Lattice Semiconductor’s exclusive synthesis partner, and Lattice will broaden its synthesis offering in its ispLEVER® design tool suite to include the industry-leading Synplify Pro logic synthesis software for higher-level designs. As of May 2008, Lattice will distribute only the Synplify and Synplify Pro synthesis products with its FPGA and CPLD devices. The companies also will work to deliver expanded support of the Synplify DSP solution to algorithmic designers who seek to accelerate their DSP designs using Lattice FPGAs.

“A critical ispLEVER design tool priority for Lattice continues to be a focus on delivering industry leading timing closure capability to FPGA designers,” said Chris Fanning, corporate vice president, enterprise solutions. “Lattice is excited to bundle Synplify Pro’s leading FPGA synthesis technology with our ispLEVER design tool suite, and to offer our customers better performance and logic efficiency capabilities.”

According to Joe Gianelli, vice president of business development and strategic alliances at Synplicity, “With this deeper relationship, Lattice and Synplicity will more effectively work together to improve their collective tool flows and performance for increased customer satisfaction. Designers will continue to experience the real benefits of our ongoing relationship, especially when implementing exciting new products like the Lattice ECP2M™, LatticeXP2™ and LatticeSC™ families of high-performance FPGAs.”

Synplicity’s Synplify and Synplify Pro synthesis software products support all Lattice devices, including the new LatticeECP2M and LatticeXP2 FPGA families, creating powerful solutions for aerospace, wireless, telecom and digital multimedia applications. Through advanced 90-nm silicon technology, an optimized architecture and proprietary circuit design, Lattice devices reduce total solution costs.

Lattice Semiconductor Corporation provides the industry's broadest range of Programmable Logic Devices (PLD), including Field Programmable Gate Arrays ( FPGA), Complex Programmable Logic Devices (CPLD), Mixed-Signal Power Management and Clock Generation Devices, and industry-leading SERDES products.

Lattice continues to deliver "More of the Best" to its customers with comprehensive solutions for system design, including an unequaled portfolio of high-performance, non-volatile, and low-cost FPGAs.
