Digital Systems Design
Final Exam
Course Introduction
Digital Systems Design introduces students to the principles and practices of designing digital electronic systems, focusing on the fundamental building blocks such as logic gates, multiplexers, flip-flops, and counters. The course covers combinational and sequential logic circuits, system modeling using hardware description languages (HDLs) like VHDL or Verilog, and the design and implementation of programmable devices including FPGAs. Emphasis is placed on the analysis, synthesis, and optimization of digital circuits, as well as practical aspects of testing and troubleshooting. Through theoretical learning and hands-on laboratory experience, students develop the skills necessary to design, implement, and evaluate digital systems for various engineering applications.
