The issues of analysis and circuit design of electronic devices in the computer-aided design system OrCAD 17.2 from Cadence are outlined. The modeling of various electronic circuits is considered in the free educational program of the schematic graphical project editor OrCAD Capture Lite, designed for creating circuit diagrams and modeling in the PSpice 17.2 program. Basic methods of working in OrCAD 17.2 are studied: creating projects, modeling modes for DC and AC circuits, transients, long lines, multivariate analysis, Monte Carlo analysis, temperature analysis, noise analysis, analog behavioral models, modeling digital and mixed circuits, creating hierarchical projects. The issues of preparing diagrams for the design stage of printed circuit boards are considered, examples of manual routing in the printed circuit board editor OrCAD PCB Editor and automatic routing in OrCAD PCB Router are given. The book is written on the basis of technical documentation from Cadence and can serve as a user guide when working with the latest versions of OrCAD (OrCAD 16 and OrCAD 17).
