AWR Integrates Analog Devices' Analog-to-Digital Converter Models with Visual System Simulator Design System
Applied Wave Research, Inc . (AWR®), a provider of electronic design automation (EDA) software, announced the integration of Analog Devices' analog-to-digital converter models (ADIsimADCT) with AWR's Visual System SimulatorT 2004 (VSS) design system. With this combination of capabilities, radio-frequency (RF) and baseband design engineers who use VSS software to develop today's wireless communications systems, can now quickly and easily model the actual performance of Analog Devices' ADCs in a system block diagram.
"The combination of VSS software and Analog Devices' ADIsimADC models is a giant step forward in being able to accurately predict and analyze the performance characteristics of a specific A/D converter part number over various input and operating conditions," said Brad Brannon, staff applications engineer in the high-speed converter group at Analog Devices. "Every converter genre exhibits unique 'real world' behavior patterns, and this tool helps minimize the design surprises that tend to result from basing performance assumptions strictly on data sheet specs."
"The introduction of the analog-to-digital converter models into VSS 2004 software enables RF and baseband system designers to simulate the effects of actual devices in their system architecture," said George Chrisikos, director of engineering for systems development at AWR. "This new capability provides engineers with the ability to make design tradeoffs at the system level, ensuring that design specifications are met early in the development process, thus reducing development cycles and time-to-market. This modeling capability is an exciting enhancement to the functionality of the VSS 2004 product."
The ADIsimADC software design tool is based on proprietary behavioral modeling technology used in Analog Devices' state-of-the-art design labs. By using such advanced models in VSS software, designers can now reduce risk during the system design phase by running simulations across various system parameters while using "real world" device models. This eliminates the need to transcribe parameters obtained from an ADC product specification sheet into a generic ADC model where, more often than not, such a model does not have either one-for-one correspondence with the specification sheet or a complete selection of essential parameters. Furthermore, this model may not have direct correlation to the physical device's performance.
The VSS product is a comprehensive software suite for the design of complete, end-to-end communications systems. VSS technology uses a complex envelope simulation engine that enables systems and circuit designers to work together within a common simulation framework to perform interactive, top-down analysis of analog and digital communications systems and RF sub-systems. VSS software, with its core algorithmic advantages, provides an extremely fast simulation engine that reduces overhead and eliminates simulation bottlenecks, speeding designs to implementation.
