Electrical circuits constitute the core of many courses at the undergraduate level in electrical and electronics engineering. For most undergraduate students, learning and analyzing such circuits are a difficult process. A significant drawback of Simulation Program with Integrated Circuit Emphasis (SPICE)-based simulation tools in terms of e-learning is that they only generate circuit simulation outputs, such as the current and voltage of electrical elements contained in a particular circuit. The users are not provided with the detailed information about the steps that are followed to obtain the related outputs. This study describes the development of a new software tool, called ECDAT (a shorthand for the Electrical Circuit Description and Analysis Tool), which can serve as a practical component of electrical circuits courses. The developed tool currently analyzes simple direct electric circuits in a similar way as the existing circuit analysis and simulation ones, and it produces an output document that includes the certain equations and intermediate calculations, using the well-known circuit laws differently from the previous works. Another contribution of the study is that, unlike the modified nodal analysis method used in SPICE-based circuit analysis programs, it employs a graph analysis method for circuit analysis.

直流电路分析工具的开发与实现

电路是电气和电子工程本科阶段许多课程的核心。对于大多数本科生来说，学习和分析这样的电路是一个艰难的过程。就电子学习而言，基于集成电路重点仿真程序 (SPICE) 的仿真工具的一个显着缺点是它们仅生成电路仿真输出，例如包含在特定电路中的电气元件的电流和电压。未向用户提供有关获取相关输出所遵循的步骤的详细信息。本研究描述了一种名为 ECDAT（电路描述和分析工具的简写）的新软件工具的开发，该工具可作为电路课程的实用组成部分。开发的工具目前以与现有电路分析和模拟类似的方式分析简单的直接电路，并使用与以前工作不同的众所周知的电路定律生成包含某些方程和中间计算的输出文件。该研究的另一个贡献是，与基于 SPICE 的电路分析程序中使用的改进节点分析方法不同，它采用图形分析方法进行电路分析。
