I am an electrical engineer, I want to use LTspie for circuit simulation design analysis. As for my biography, there may not be much to write. My undergraduate study is in the field of optoelectronic information, and I don't have enough knowledge of electronic technology. After graduation, I mainly use analog circuits and digital circuits, which are mostly simple. However, circuit simulation is an important step in circuit design, so I want to learn to use LTspie. I used multisim before. Although it is powerful, it is more convenient for simple applications or LTspie.
