Digital systems have such a prominent role in everyday life that we refer to the present
technological period as the digital age. Digital systems are used in communication, busine
ANALYSIS OF CASE STATEMENTS
The common practice is to use casez statement in RTL coding. Use of casex is strongly
discouraged. Now we will discuss whether casex is such a bad construct. Before we start
let me say, all case statements are synthesizable.
A hazard is a condition in a logically correct
digitalcircuit or computer program that may lead to a logically incorrect output

INTRODUCTION TO EXPERIMENTS
This chapter presents 17 laboratory experiments in digital circuits and logic design. The
experiments give the student using this book handson experience. The dig
Design at the Register Transfer Level
The behavior of many digital systems depends on the history of their inputs, and the
conditions that determine their future actions depend on the results of previous actions.
Such systems ar
Memory and Programmable Logic
A memory unit is a device to which binary information is transferred for storage and from
which information is retrieved when needed for processing. When data processing takes
place, information fro
Registers and Counters
A clocked sequential circuit consists of a group of flipflops and combinational gates. The
flipflops are essential because, in their absence, the circuit reduces to a purely combinational
circuit (provided th
Synchronous Sequential Logic
Hand-held devices, cell phones, navigation receivers, personal computers, digital cameras,
personal media players, and virtually all electronic consumer products have the ability to
send, receive, st
Logic circuits for digital systems may be combinational or sequential. A combinational
circuit consists of logic gates whose outputs at any time are determined from only the
present combination of inputs. A c
Gate-level minimization is the design task of finding an optimal gate-level implementation of the Boolean functions describing a digital circuit. This task is well understood,
but is difficult to execute
Boolean Algebra and Logic Gates
Because binary logic is used in all of todays digital computers and devices, the cost of
the circuits that implement it is an important factor addressed by designersbe they
