Highlights • Determining which components are over-stressed by using Smoke (Stress) analysis or observing the affects of component variations on yield by using Monte Carlo analysis helps to prevent "in-field" failures • Identifying which components most affect yield allows you to tighten the tolerances of sensitive components and loosen the tolerances of non-sensitive components to optimize costs • Determining the best component values to meet design performance goals and constraints helps to fine-tune designs faster than trial and error • Simulating the behavior of a circuit statistically when part values are varied within their tolerance range helps to explore operating conditions The PSpice Advanced Analysis simulation engines help maximize design performance, yield, cost-effectiveness, and reliability Upgrading to OrCAD ® EE (PSpice ® ) Designer Plus provides the PSpice Advanced Analysis simulation engines that are used in conjunction with core PSpice simulation to maximize design performance, yield, cost-effectiveness, and reliability. These simulation capabilities—Sensitivity, Monte Carlo, Smoke (Stress), Optimizer, and Parametric Plotter—help you deal with the problems of manufacturing variations of electronic components by providing you with an in-depth understanding of circuit performance that goes beyond basic validation. Overview Manufacturing variations inherent in the electronic components that make up your circuits can greatly affect their function and performance. These manufacturing variations are generally expressed as tolerances on key specifications of the components and it is not usually possible or practical to manually test a circuit to the complete range of tolerances of all the components. Without simulation, a common option is to simply specify tighter tolerances on all the components to try to account for the varia- tions. But tighter device tolerances mean higher-priced compo- nents, increasing design costs. The other option is to hope for the best and assume that variations will not impact a circuit's function or performance to the point of a failure. While this assumption may save costs, it tends to result in lower yields. A robust design can be produced by taking component toler- ances into account such that the circuit functions properly throughout the range of all the possible combinations of component values. Simulation with PSpice Advanced Analysis provides a proven, quick, and easy way to perform circuit calcu- lations to determine and account for the component variations. With this powerful environment and capability, you can be confident that circuits function as intended and the tolerances specified are in-line with your requirements: not so tight as to be overly costly and not so loose as to produce inordinate numbers of defective products.
