OrCAD PSpice Designer Plus 2 In addition, integration with MathWorks MATLAB Simulink provides an analysis flow enabling multi-domain simulation, such as electromechanical co-simulation. Simulation Features PSpice Advanced Analysis simulation is used to improve your design's performance, yield, and reliability. Capabilities such as temper- ature and stress analysis, worst-case analysis, Monte Carlo analysis, and automatic performance optimization algorithms improve design quality and maximize circuit performance. Sensitivity analysis Sensitivity analysis identifies which component parameters are critical to your circuit performance goals by asking such questions as, "Does the value of R1 affect my bandwidth more than the value of R2?" It examines how a component's inherent manufacturing variations affect circuit behavior both individually and in comparison with other components by varying manufacturing tolerances to create worst-case (minimum and maximum) results. Sensitivity analysis can also be used to identify which components affect yield the most, allowing you to choose the sensitive components with tighter tolerances. The analysis allows evaluation of yield versus cost tradeoffs. Optimizer analysis Optimizer analyzes analog circuits and systems, fine-tuning design parameters faster than trial-and-error to find the best component values to achieve your performance goals and constraints. Circuit specifications can be as simple as an output voltage maximum, a more complex output calculation such as the cutoff frequency for a low-pass filter, or an entire curve using the Optimizer curve-fitting capability. Smoke (Stress) analysis Smoke (Stress) analysis warns of component stress due to power dissipation, increases in junction temperature, secondary break- downs, or violations of voltage and current limits. Over time, these stressed components can cause your designs to fail, often long after the design stage. Smoke (Stress) analysis compares circuit simulation results with the component's safe operating limits, and if the limits are exceeded, Smoke (Stress) analysis identifies the problem parameters. Monte Carlo analysis Monte Carlo analysis predicts the behavior of a circuit statistically when multiple components are varied within their tolerance ranges. By changing all the parts of your circuit randomly within their tolerances over a number of simulations, you can approximate the yield of building numerous boards. These measurements help you to determine what percentage of boards has the potential to be out of spec and affecting yield. If the percentage is too high, running Sensitivity analysis can help identify the component(s) that might need to be tightened up. For example, you can swap a 10% tolerance component with a 1% component to improve your yield, or conversely, if you have components that aren't too critical, you can use 10% or 20% parts to reduce cost. Parametric Plotter The Parametric Plotter enables sweeping of multiple parameters once a simulated circuit has been created. It also provides an efficient way for you to analyze sweep results, sweep any number of design and model parameters (in any combination), and view the results in PPlot or Probe in tabular or plot form. Open Architecture Platform Enabling an extensible and customizable design environment, OrCAD's open architecture platform incorporates a highly integrated Tcl/ HTML5 programming infrastructure that allows the creation or enhancement of features, functionality, design capabilities, and flows. The Tcl programming interface provides programming access to the user interface, command structure, simulation data, and algorithm process. Custom features that do not exist natively can be created, further enhancing and extending the PSpice environment.
