"OrCAD概述及电路图绘制技巧详解"

The presentation titled "OrCAD Overview and Circuit Diagram Drawing" consists of 95 slides in the PowerPoint file "Components.pptx." The content of the presentation covers a comprehensive overview of OrCAD, the process of drawing circuit diagrams, editing and modifying circuit diagrams, editing and modifying circuit element properties, as well as displaying and printing circuit diagrams. The first section of the presentation provides an introduction to OrCAD, including the process of circuit design. It discusses traditional and modern design methods, highlighting the shift from manual circuit drawing and testing to computer-aided design (CAD) and electronic design automation (EDA). The traditional method involves setting a scheme, drawing the circuit diagram, soldering, testing, modification, and finalizing the printed circuit board (PCB) design. In contrast, the modern approach utilizes computer software to draw, analyze, optimize, and statistically assess circuit performance, leading to the PCB design and fabrication process. The presentation also delves into the concepts of CAD, CAE, and EDA, emphasizing their roles in computer-aided design and electronic design automation. CAD, which stands for Computer-Aided Design, emerged in the 1970s-1980s and paved the way for electronic design automation (EDA). The presentation outlines the need for a computer and electronic design CAD software to facilitate modern circuit design processes. Overall, the presentation serves as an informative guide for individuals involved in circuit design, providing insights into the use of OrCAD, the evolution of design methods, and the significance of computer-aided design and electronic design automation in the field of electronic circuit design. It demonstrates the transition from traditional design methods to modern computer-aided approaches, reflecting the advancements in technology and its impact on the design and development of electronic circuits.
