www.cadence.com 3 Allegro PSpice Simulator • Transmission line models that incorporate delay, reflection, loss, dispersion, and crosstalk • Digital primitives, including bi-directional transfer gates with analog I/O models • Battery models allow accurate simulation of the discharge cycle and operating conditions • Comprehensive model set for various electromechanical and mechanical devices like BLDC, flywheel, resolver, tacho, etc. • Built-in library component for commonly used mathematical functions • Models for Tiny Switch-III family devices and new Optocoupler devices The Device Model Interface capability in PSpice offers enables simulation of system designs using different kinds of abstractions. With the GUI, users can define C/ C++, System C, and Verilog A components and simulate them in the simulator. Model library Users can select from more than 33,000 analog and mixed-signal models of devices made in North America, Japan, and Europe. Also included are more than 4,500 parameterized models for BJTs, JFETs, MOSFETs, IGBTs, SCRs, magnetic cores and toroids, power diodes and bridges, operational amplifiers, optocou- plers, regulators, PWM controllers, multipliers, timers, and sample-and-holds. Model editing It's easy to extract a model of a supported device type—simply enter the required data from the device's datasheet. Once you have extracted, the PSpice Model Editor automatically creates a part of the model, making it available for immediate use in the design. Behavioral modeling Functional blocks are described using mathematical expressions and functions, which allow designers to leverage a full set of mathematical operators, nonlinear functions, and filters. Circuit behavior can be defined in the time or frequency domain, by formula (including Laplace transforms), or by look-up tables. Error and warning messages can be specified in different conditions. Users can easily select parameters, which have been passed to subcircuits in a hierarchy, and insert them into transfer functions. New behavioral capabilities include mathematical functions like in(x), exp(x), and sqrt(x). Magnetic parts editing The Magnetic Parts Editor helps designers overcome issues involved in manually designing transformers. Users can design magnetic transformers and DC inductors, and generate simulation models for trans- formers and inductors that can then be used in Allegro PSpice Simulator circuits. The Magnetic Parts Editor also allows designers to generate data required for manufacturing the transformers or inductors. The manufacturer's report that is generated by the PSpice Magnetic Designer after the completion of the design process contains the complete data required by a vendor to develop the trans- former for commercial use. The modeling design capabilities help you generate accurate PSpice models, including winding resistances and various parasitics. Encryption The encryption feature allows models to be encrypted using 56-bit DES algorithm. SLPS Cadence simulation technology and the MathWorks' MATLAB Simulink package integrate two industry-leading simulation tools into a powerful co-simulation environment (SLPS). However, in order to run PSpice SLPS one must have a PSpice SLPS license along with a PSpice or Allegro PSpice Simulator license. Simulink is a platform for multi-domain simulation and model-based design of dynamic systems. The SLPS integration allows designers to perform system-level P(u) 0(P) = 2 Polynomial SLPS Relay average outdoor temperature daily temperature variation heater blower constant Add1 Gain2 Gain1 1/Req Integrator Scope1 -K- 32 50 -K- 5/9 -K- 1 s Figure 3: SLPS integration allows designers to interface the Allegro PSpice Simulator with Simulink and then observe the waveforms after Simulink-Allegro PSpice Simulator co-simulation Figure 2: Allegro PSpice Simulator provides a complete simulation environment including simulation waveform analysis with cross-probing and bias results displayed on the schematic
