From the project
A Tic Tac Toe game made completely using digital logic. A semester project for the course Digital System Design
A first year graded project I submitted for my course in Digital System Design (Winter Semester, Vellore Institue of Technology, Chennai). This is a Tic Tac Toe game that uses only digital logic to play the game. PCB Design was done on KiCad , an open source PCB Design software. I simulated the circuit in another open source digital simulator called Digital.exe (which is based on another software called Logisim) by Helmut Neemann which I downloaded from his GitHub repository. Digital.exe helped me immensely in my project as I cannot have simulated my project without this software for free.…
