Welcome to Digital Logic design COE 202 & CS 151. This dedicated course is aimed to students teaching in the faculty of computer ( for both sections COE & CS). This course include Introduction to information representation and number systems. Boolean algebra and switching theory. Manipulation and minimization of completely and incompletely specified Boolean functions. Physical properties of gates: fan-in, fan-out, propagation delay, timing diagrams, and tri-state drivers. Introduction to hardware description languages (HDLs). VHDL. System modeling using VHDL. Combinational circuit analysis and design, multiplexers, decoders, comparators, and adders. Sequential circuit analysis and design, basic flip-flops, clocking and timing diagrams. Registers, counters, RAMs, ROMs, PLAs, PLDs, and FPGAs.
