Course Description
This course provides a modern introduction to logic design and the basic building blocks used in digital systems, in particular digital computers.
It starts with a discussion of combinational logic: logic gates, minimization techniques, arithmetic circuits, and modern logic devices such as field programmable logic gates.
The second part of the course deals with sequential circuits: flip-flops, synthesis of sequential circuits, and case studies, including counters, registers, and random access memories.
State machines will then be discussed and illustrated through case studies of more complex systems using programmable logic devices. Different representations including truth table, logic gate, timing diagram, switch representation, and state diagram will be discussed.

Course Description: Lab
The course has an accompanying lab component that integrates hands-on experience with modern computer-aided design software including logic simulation, minimization and an introduction of the use of hardware description language (VHDL).
The hands-on assignments will make use of the Xilinx ISE tool chain for the design and implementation of a variety of projects.
The labs will give you direct feedback on how your design performs and will be a great learning tool.

Digital Model of a Transistor
We make abstraction of the signals: 0 or 1 As a result a transistors can be
considered a switch (on or off; 1 or ;):

What is an IC? An Integrated Circuit is a miniaturized
electronic circuits whose components (transistors, resistors, capacitors) are build on the surface of a semiconductor wafer, using the same planar fabrication technology.

How to Design such complex systems?
Make Abstractions
Divide and Conquer
Reuse previous designs (IP)
22
Importance of Abstraction
Real world is very messy – can be described by the laws of Physics
For EE, CS, these laws are Maxwell’s equations (Electromagnetics – ESE310)
Simplifications (abstractions):» Lumped models (R, L, C, V)» Amplifier level» Digital abstraction:
– Gate level (inverter, AND gates)– …
23
Digital Abstractions (simplifications) Transistors switches Gates: inverter, AND, OR, etc. Next level: Combinational logic Next: Synchronous and sequential logic Next: Computational architecture: X86 Next: Language Abstraction Software System Abstraction (OS, Linux,
Windows)
Thanks to these levels of abstractions one can build useful things, e.g. iPad, etc.
