OrCAD datasheets

OrCAD PSpice Designer 2 tries such as aerospace, medical, power electronics, and automotive. It is also utilized extensively within the research community as a reference implementation. It is capable of simulating your designs from simple circuits, complex electronics, and power supplies to radio-frequency systems and targeted IC designs. With built-in mathematical functions, behavioral modeling, circuit optimization, and electromechanical co-simulation, the OrCAD PSpice environment goes far beyond general circuit simulation. Included in the OrCAD EE (PSpice) Designer product with OrCAD PSpice, OrCAD Capture provides fast, easy, and intuitive circuit capture, along with highly integrated flows supporting the engineering process. With an upgrade to the OrCAD EE (PSpice) Designer Plus product, Advanced Analysis simulation engines provide you with functional simulation to improve design performance, cost-effec- tiveness, and reliability. In addition, integration with MathWorks MATLAB Simulink provides an analysis flow enabling multi-domain simulation, such as electromechanical co-simulation. Simulation Features Simulation OrCAD PSpice simulation technology provides DC, AC, and transient analysis, so you can test the response of your circuits to varying inputs. It also provides digital worst-case timing analysis to help you find timing problems that occur with circuit signal transitions. Mixed-signal designs can also be verified where the analog portions have digital content embedded. Integrated analog and event- driven digital simulations mean improved speed without loss of accuracy, and complex measurements can be created and viewed as the simulation progresses. Results and data display The extensive capabilities of OrCAD PSpice Probe enable you to make complex measurements, cross-probe with the circuit design, view waveforms in multiple plots, and provide you with an expanded set of mathematical functions to apply to simulation output variables. OrCAD PSpice Probe also enables the measurement of performance characteristics of a circuit using built-in functions and the creation of custom measurements. With OrCAD PSpice Probe, you can plot both real and complex functions of circuit voltage, current, and power consumption, including Bode plots for gain and phase margin and derivatives for small-signal characteristics. You can display Fourier transforms of time domain signals or inverse Fourier transforms of frequency domain signals. You can also vary component values over multiple runs and quickly view results as a family of waveforms with parametric, Monte Carlo, and worst-case analysis. Models and modeling Along with numerous vendor models and model libraries available online, the OrCAD PSpice model library offers more than 30,000 analog and mixed-signal models. This library includes parameterized models such as BJTs, JFETs, MOSFETs, IGBTs, SCRs, discretes, operational amplifiers, optocouplers, regulators, PWM controllers, and multipliers. A device equations developer's kit (DEDK) allows implementation of new and custom internal model equations. You can describe behavior modeling though functional blocks using mathematical expressions and functions, which allow you 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. The integrated OrCAD PSpice Model Editor provides you with an easy way to create models using device characteristic curves. An intuitive stimulus creation capability makes it easy to create a variety of simulation stimuli. Any shape stimulus can be created with built-in functions and can be described parametrically or freehand with the mouse to draw piece-wise linear (PWL) signals. Flexibility and control The OrCAD PSpice CheckPoint Restart feature provides greater control over your simulations. You can stop and restart, generate checkpoints at specified points in time of a simulation, and then restart the simulation from a specific checkpoint. In addition, you can add assertions to detect failure or warning conditions as the simulation progresses, so you don't need to wait for complete simulations to detect error conditions. Simulation profiles allow binding of models and stimulus to enable simulation of different test conditions using same schematic, and you can also queue-up simulations for overnight results.
