Carbon Fuels Growth With Additional $5M Funding

September 14, 2006

Next Generation Product Development Underway

WALTHAM, MA -- (MARKET WIRE) -- 09/14/2006 -- Carbon Design Systems -- an innovator in ESL tools for software validation prior to silicon -- announced today that it has raised $5M in its series D round of financing. In addition, Carbon mentioned that Edgar Masri will remain on its board of directors, after being recently appointed the new president and chief executive officer of 3Com, a leader in networking products.

Participating venture capital firms included all previous series C investors: Matrix Partners, Flagship Ventures, and Commonwealth Capital. This round of investment brings Carbon's total financing to $25 million, with each venture capital firm having an equal equity stake.

"Carbon will use this funding to drive new product development, with our recently announced Replay™ being the first in a new round of innovations brought to market," proclaimed Rick Lucier, president and CEO of Carbon. "Expect to see Carbon setting the benchmark in software validation by which others are measured."

"Carbon is implementing a big vision that allows electronic systems, including the software content to be validated before fabrication," expressed Edgar Masri, president and CEO of 3Com. "Their differentiation is supporting multiple levels of design abstraction, including fast models derived from RTL -- the world's hardware design language."

"Carbon is removing the adoption barriers for system-level design methodologies," stated Steve Ricci, managing director and vice chairman of Flagship Ventures. "Carbon has the momentum to capitalize on this fast growing market segment."

"Traditional EDA customers have been saddled with outdated simulation and emulation products," declared R. Stephen McCormack, general partner and co-founder of Commonwealth Capital. "It takes new, innovative companies like Carbon to bring revolutionary products to market."

About Carbon

Carbon's products in conjunction with SystemC™ simulation platforms, such as ARM® RealView® SoC Designer, enable the first effective system validation solution. Carbon dramatically reduces design cycle time by allowing legacy IP and RTL to be used early for architecture profiling and tradeoff analysis all the way through software and hardware integration. Unlike the time-sink to create behavioral models or bring-up an expensive emulator, Carbon generates high-performance hardware-accurate simulation models from RTL in minutes.

Carbon's new approach accelerates time-to-profit by enabling software validation to occur in parallel with hardware development. Problems can be found and resolved early in the design cycle -- rather than waiting for FPGA prototypes to be built or silicon to be delivered.

The company is headquartered at 375 Totten Pond Road, Suite 100/200, Waltham, MA. 02451. Telephone: 781.890.1500, Fax: 781.890.1711, Email: info@CarbonDesignSystems.com, Website: www.carbondesignsystems.com or www.easypass2esl.com
