Rochester, NY– EMA Design Automation and AEi Systems have released the Power IC Model Library. The PSpice library incorporates over 150 time-domain simulation models for power electronic designs and gives designers the ability to plug in a model, representative of the actual IC, and simulate the switching performance under actual operating conditions.

“Many EDA vendors only have access to information in the data sheets, which is not sufficient when modeling a controller or regulator,” said Charles Hymowitz, managing director of AEi. “The data sheets simply do not have the level of detail required, and companies who rely solely on data sheet input produce substandard and inaccurate models.”

The models in this library enable designers to perform high-speed, cycle-by-cycle simulations to show true large-signal performance, simulate current-mode control using accurate modeling techniques, run CCM and DCM converter simulations, generate line and load step responses, and measure power stage loss and stress analysis for all major components.

The models are compared and verified with bench data under startup, steady state, line, and load transient conditions. Nonlinear characteristics such as propagation delay, switching speed, drive capability, maximum duty cycle/current limits and startup phenomena are all accurately modeled. Designers can directly compare the performance of components from various vendors and analyze the effects of different implementations such as peak current mode control, hysteric current control, low voltage and low operating current.

NORWALK, OH -- In July, EPIC Technologies completed the certification process for ISO 13485:2003 in its Norwalk and two Juarez, Mexico, facilities. It has also completed surveillance audits and recertified these facilities to the ISO/TS 16949:2002 standard.

ISO 13485:2003 is a quality management standard for medical device manufacturers. ISO/TS 16949:2002 was developed to support the automotive industry.

"While ISO 13485:2003 and ISO/TS 16949 are valued by medical and automotive customers because they address industry-specific quality issues, we also recognize that each of these standards drives further development of best practices in the areas of performance measurement and standardization. ISO/TS 16949 drives additional focus in the area of customer satisfaction measurement and integration of those results into focused continuous improvement efforts. The practices we adopted in support of these certifications continue to strengthen our internal systems company wide," said Jochen Lipp, VP operations and COO, EPIC Technologies.
