Analog / Mixed Signal Board Level Simulation D A T A S H E E T AccuParts™ Key Product Benefits • Over 11,7000 Models optimized for use with AccuSim™ / Eldo / ADMS / DxSim / Continuum • Complex parts have 2 or more model levels • Many primitive parts have variants • Models are 100% tested • All models work with utilities that ease the selection and placement of parts • Models can be changed on-the-fly within a simulation session The AccuParts library provides designers with an industry-leading resource for analog component models. With over 11,700 models, AccuParts included many of the most popular component models used by designers in the aerospace, automotive, telecommunications, computer, consumer and other industries. In combination with Mentor Graphics’ AccuSim or Eldo analog simulators and the Design Architect schematic capture tool for specifying and creating electronic designs, AccuParts contributes to a powerful solution for analog/mixed-signal, printed circuit board, and systems designers. AccuParts models of discrete components, such as transistors, diodes and JFETs, are based on proprietary model generation techniques that translate the datasheet parameters to the appropriate spice model parameters ensuring that the models accurately reflect the actual devices. Complex devices, such as operational amplifiers, voltage comparators, Voltage references and regulators are modeled as subcircuits using similar techniques that include often overlooked parameters like noise, temperature and loading. AccuParts also provides designers with more then 1370 accurate models of complex analog components, such as operational amplifiers, comparators, voltage regulators, and more. Modeling engineers at Mentor Graphics develop subcircuit models comprised of AccuSim II primitive models. In AccuSim II Analyses, the resulting models exhibit behavior that is comparable to that of real devices in actual circuits. Moreover, the AccuParts library offers extensive support for linear and nonlinear magnetics. Custom transformer design is made easy with the extensive transformer creation utility provided in Design Architect. The magnetic core materials and specific core geometries make use of the flexible nonlinear magnetics primitives within AccuSim II to offer the most accurate models possible. In the event the core geometry or core material is not AccuParts, the designer can use the pop-up forms to enter magnet data directly from the manufacturer’s data sheets. The AccuParts library includes over 2000 models of Power MOSFET devices, IGBTs, Thyristors, and PWM ICs based on AccuSim II primitives for use in power conversion designs. Designers access AccuParts models through Design Architect either by manufacturer part number or by using the selector guide. The Selector Guide helps designers choose parts based on their manufacturers’ specifications, thus simplifying the parts selection process. Both ANSI and conventional symbols are available for most analog components. Mentor Graphics continually develops new models for AccuParts library in response to customer requests and the availability of new analog components. Models in the AccuParts library are open—all model parameters and subcircuits are available to the designer for inspection. Designers can view and modify copies of AccuParts models as well as on-line data sheets. AccuParts models range from OpAmps to diodes and transistors.
