BEND, Ore.--(BUSINESS WIRE)--Jan. 30, 2003

Accent Optical Technologies (www.accentopto.com), a leading supplier

of optoelectronics and silicon semiconductor process control systems, today announced the placement of a high power DiVA system at Modelithics, Inc. (www.modelithics.com), a visionary company providing precision measurement services and Electronic Design Automation (EDA) software models for RF/microwave components and integrated circuits. This is the second DiVA placed at Modelithics. The first, a DiVA 225 capable of 25V and 1A operation, was installed in April, 2002 and is being used for developing non-linear models for low and medium power transistors and diodes, based on pulsed IV measurements made on packaged, chip and on-wafer device samples.

"The higher DC power handling capability of Accent's DiVA D265 Dynamic I-V Analyzer is critical to modeling higher power transistors. Thermal related performance issues rise with the total power dissipation within a transistor, causing large errors in nonlinear models for high power devices based on static DC measurements. We are pleased to be able to work with this state-of-the-art modeling aid," stated Dr. Larry Dunleavy, President of Modelithics.

Graham Riley, Director of Product Marketing for DiVA at Accent said, "The 65V/2A D265 model was developed specifically for those engineers working with higher power transistors. It has the same inherent benefits as our other DiVA models, allowing rapid device characterization under the same physical conditions seen by high frequency and RF signals. Device models fitted from DiVA derived data yield more accurate simulation results and so enable designers to carry out comprehensive virtual testing with greater confidence. This in turn can lead to higher yields and better overall application performance."
