Even experienced electronics developers can hardly predict the behavior of electrical circuits. Therefore, circuits or only critical circuit parts are analyzed either by physically constructed prototypes and subsequent measurements or by circuit simulations. The trend here is clearly towards virtually simulated measurement, as the development cycles are getting shorter and shorter, and simulations can be used very promptly to make statements that correlate with measurements. Worldwide, PSpice has been the reference simulator for years, and most component manufacturers offer PSpice simulation models on the Internet.
Based on the circuit diagram drawn for a PCB layout, a simulation can be started. If necessary, the user inserts a current source or a defined stimulus and measuring points in the circuit diagram. This procedure is similar to a physical setup with function generator and oscilloscope.
Analyze and verify your analog and mixed-signal electrical circuits with the advanced PSpice simulation tools in OrCAD.
Virtually create and test designs before developing hardware, saving you time, money and materials.
The seamless bi-directional integration between MathWorks MATLAB/Simulink and PSpice lets you easily simulate electrical circuits and mechanical,hydraulic,thermal blocks in one unified environment.
Basic functionality of PSpice is integrated in the OrCAD PCB design flow. Design intend is entered in schematic entry tool OrCAD Capture and can be used to drive a PSpice simulation and develop functionality of the circuit. Same schematic can be used for documentation and simulation. The netlist can be created and the PCB Editor uses the schematic to cross probe during placement and routing. A comprehensive integration provides broad information and avoids errors in the design process.
PSpice Feature comparison
OrCAD PCB Designer Professional includes a full version of PSpice A/D incl. Smoke option. With this feature set you can perform a stress analysis of components and ensure you have components reliability as needed. Maximum de-rating of components can be determined and thus make a statement about the component load. The load can be specified in percent via model parameters. The developer is interested in statements about the types of load: thermal at maximum current and highest possible voltage, conduction of junction temperature in °C or thermal contact resistances jC and jA, as they occur in the circuit.
