XCircuit 诞生于 1993 年夏天，最初是一个绘图程序，用于绘制约翰霍普金斯大学惠廷工程学院兼职项目的本科电气工程课程的电路图。从那时起，它已经扩展到包含原理图捕获，并被世界各地的人们用于演示和作为 EDA（电子设计自动化）工具。

XCircuit was written and is maintained by Tim Edwards, currently with MultiGiG, Inc., of San Jose, California (Tim lives in Maryland and works remotely). XCircuit started life in the summer of 1993 as a drawing program to render circuit diagrams for an undergraduate electrical engineering course in the Johns Hopkins University Whiting School of Engineering Part-time programs. Since then, it has expanded to encompass schematic capture and is used by people all over the world for both presentations and as an EDA (Electonic Design Automation) tool.
