In this course, students will learn design principles for combinational and sequential digital circuits, using TTL components as well as field programmable gate arrays. The functional design using standard mathematical description and VHDL will be used for designing and realization of various digital circuits. The laboratory classes will be arranged as a set of laboratory tasks and practical examples. Some laboratory lessons will be focused on VHDL and its application for realization of basic digital circuits using FPGAs, their simulations and emulations as well as creating more advanced digital blocks.
The prerequisite is the knowledge on basic mathematic operations at the high school level.
