This lecture provides a basic introduction to Logisim Evolution, a software tool essential for designing and simulating digital logic circuits. The instructor begins by connecting to the EPFL VDI and launching Logisim, explaining its interface and functionalities. The focus is on fundamental components such as inputs and outputs, starting with the pin component, which allows users to set binary values. The instructor demonstrates how to connect a pin to a NOT gate and an LED, illustrating how the circuit operates based on input values. The lecture progresses to more complex inputs, including multi-bit pins and clock inputs, explaining their significance in circuit design. The instructor also covers various gates, including NOT, AND, and OR gates, detailing their functions and how to implement them in Logisim. By the end of the lecture, students gain a foundational understanding of using Logisim for digital circuit design, preparing them for more advanced topics in their course.
