CoreSim Replaces Obsolete ASIC with Board Powered by LatticeEC FPGA

8/24/2005 - Lattice Semiconductor Corporation (NASDAQ: LSCC) announced that advanced design services company CoreSim has selected the LatticeECTM FPGA to replace an obsolete ASIC for one of its customers. CoreSim has delivered a drop-in component adapter board based on the LatticeEC device to replace the ASIC. The board has a low operating frequency of 60-70 MHz and will be used in an aerospace ground base application. The LatticeEC FPGA is used for phase and bit detection to synchronize incoming signal traffic.

"This project presented some interesting challenges," said Mike Alam, Project Team Leader. "Not only was the ASIC obsolete, it could not be manufactured in any case because most of the original design documentation was lost or unverified. It was a design challenge that required CoreSim's unique design and verification process, but also it clearly called for a low cost programmable logic device. The LatticeEC FPGA offered very attractive features that helped us make our decision. Primary among them was that the Lattice device could be configured using a low cost, standard off the shelf SPI Flash boot PROM. We also were impressed with the part's 5-volt tolerance and signal overshoot/undershoot characteristics. We also liked the density migration available within the LatticeEC family of seven devices.

"The local Lattice support was outstanding," Alam continued. "The Lattice representatives were responsive, knowledgeable and available."

Project Designer Karen Chase used the Lattice ispLEVER® design tools. "I was very pleased with how easy it was to set up the design tools," said Chase.

"It's gratifying to see customers such as CoreSim selecting our LatticeEC and LatticeECPTM low cost, high performance FPGAs," said Stan Kopec, Lattice vice president of corporate marketing. "We were determined to provide customers with FPGAs that were low in cost but high in features and performance, and the enthusiastic reaction to the devices tells us we've achieved that goal," Kopec concluded.

About the LatticeECP-DSPTM and LatticeEC FPGA Families
The LatticeECP-DSPTM and LatticeEC FPGA device families are architected to provide the most optimized feature sets combined with the lowest total solution costs of any FPGAs. The new LatticeECP-DSP products, targeted for high-performance DSP applications, provide up to a 50% performance and 75% logic utilization improvement over other low cost solutions when implementing common DSP functions. The LatticeEC FPGA product family, targeted for general-purpose FPGA applications, is a precise and targeted response to the market's explosive demand for low cost, architecturally streamlined logic solutions. Through advanced 130nm silicon technology, an optimized architecture and proprietary circuit design, the new Lattice devices lower total solution costs by up to 30% to 50% compared with existing FPGA solutions, and are expected to broaden the adoption of FPGAs within the $20 billion ASIC marketplace.

About CoreSim
CoreSim, headquartered in Ottawa, Canada, is a world leader in advanced analysis and design of new circuit boards and design cost reduction of existing products. Companies developing new products partner with CoreSim experts to avoid costly respins and design marginality through concurrent functional and parametric modeling techniques up to Multi GHz frequencies. For existing products, these analysis techniques along with real time system vector capture and hardware modeling create accurate models of hardware / software functional and parametric operating margins. This "digital fingerprint" is the starting point for aggressive design cost reduction. The replacement board model is matched to the original golden model prior to fabrication for first pass success.
