New Release Of Lattice FPGA Design Tools Extends Performance And Productivity

- ispLEVER Design Tool Suite Includes Industry-First SSO Analyzer for
SERDES Design and New, Upgraded Synthesis and Simulation Tools -

HILLSBORO, OR - MAY 5, 2008 - Lattice Semiconductor Corporation (NASDAQ: LSCC) today announced the immediate availability of its ispLEVER( 7.1 FPGA design tool suite. The new tool release delivers a number of new functional and performance-enhancing features, including the industry's first dedicated FPGA Simultaneous Switching Output (SSO) Analyzer. The SSO Analyzer enables FPGA designers to actively analyze and optimize I/O pin placement and output switching characteristics to minimize undesirable noise and ground bounce on a printed circuit board. To enable designers to achieve higher levels of productivity, the ispLEVER 7.1 design tools also deliver up to 30% faster FPGA design compile times and now support multi-processor powered design compilation to achieve the fastest timing closure.

"Lattice's highest design tool priority continues to be delivering industry leading timing closure capability to FPGA designers," said Chris Fanning, corporate vice president, enterprise solutions. "The ispLEVER design tool suite now delivers industry leading performance and innovative productivity tools that enable FPGA designers to optimize their designs more productively and efficiently."
An enhanced Power Calculator enables FPGA designers to analyze and optimize power requirements early in their design. The Lattice Power Calculator includes an exceptionally user-friendly interface that enables power analysis at the block level and examination of "what-if" scenarios by changing design environment variables.
This release marks the addition of Synplicity's Synplify( Pro and Aldec's Active-HDL( Lattice Edition as principal elements of the ispLEVER FPGA design flow. "We're excited about our new OEM tool bundle," said Tim Schnettler, director of design tools marketing at Lattice. "Lattice now offers the very high performance, mixed language design flow that today's complex designs demand."
Enthusiastic Support from Partners
Joe Gianelli, Synplicity vice president, said, "We're excited to expand our partnership with Lattice to include our Synplify Pro software with the ispLEVER tool suite. Lattice customers now will be able to access the industry's number one FPGA synthesis tool in a solution that enables them to take full advantage of Lattice's high performance FPGA architectures."

"Aldec's fast, mixed language verification solution bundled in the ispLEVER tool suite is designed to produce results more quickly than any other FPGA solution," said David Rinehart, Aldec vice president of marketing. "Our new Lattice OEM partnership is focused on delivering flexible, fast verification capabilities to users of Lattice's innovative FPGA products."
Mentor Graphics Precision RTL synthesis and ModelSim simulator continue to be supported as standalone tools for Lattice FPGA design and are available directly from Mentor Graphics. Both Lattice and Mentor Graphics remain fully committed to support Lattice's existing and future programmable devices with Mentor Graphics tools.
Daniel Platzker, product line director, Mentor Graphics Design Creation and Synthesis Division, said, "The engineering effort we've engaged in with Lattice over the past several years has allowed us to develop the only physical synthesis solution for Lattice devices and offer a world class design flow that will stand up to the stringent requirements of high speed FPGA design, now and in the future. We will continue our joint development in the interests of supporting our mutual customers with the best tools possible."

New Features

The ispLEVER 7.1 release includes enhancements and new features in virtually every aspect of the design flow. A partial list of new features and enhancements includes:
* Windows Vista O/S Support
* "Find Module" Function in Project Navigator

Higher Performance

The ispLEVER 7.1 release marks a new standard in performance, encompassing improvements in post-route design operating frequency of up to 5% and runtime reductions by as much as 30% for larger designs. These improvements decrease costs, speed-timing closure and help users deliver the best solutions more quickly.

LatticeMico32(tm) Embedded Microprocessor Release

A recent release of the LatticeMico32 embedded processor solution included Linux O/S-based tools, VHDL language support (through VHDL wrappers of the Verilog IP) and added arbitration support. The ispLEVER 7.1 release seamlessly integrates the LatticeMico32 Mico System Builder into its design flow. The new arbitration support automatically selects the appropriate Wishbone Bus arbitration scheme when the microprocessor platform is generated, enabling shared-bus or slave-side arbitration. This capability allows multiple master ports efficient access to multiple slave ports.
Lattice also has recently added the uClinux O/S to a portfolio that already included RTOS support from Micrium and µITRON. The release of ispLEVER version 7.1 is the first that includes the latest LatticeMico32 support.

About the Lattice ispLEVER Design Tool Suite

The ispLEVER design tool suite is Lattice's flagship FPGA design environment for use with its latest FPGA products. It provides a complete set of powerful tools for all design tasks, including project management, IP integration, design planning, timing analysis, place and route, in-system logic analysis and more. The ispLEVER tool suite is provided on CD-ROM and DVD for Windows Vista, UNIX and Linux platforms.
About Aldec's Active-HDL Lattice Edition

The new OEM agreement between Aldec and Lattice enables Lattice to bundle the Active-HDL Lattice Edition with its ispLEVER suite, and Active-HDL Lattice Web Edition with Lattice's ispLEVER Starter and ispLEVER Classic design tool suites.
Active-HDL Lattice Edition features mixed language simulation of VHDL and Verilog, co-simulation with The MathWorks( Simulink(, and many advanced verification and debug features such as Language Assistant, Code Execution Tracing, Advanced Breakpoint Management and Memory Viewing.
