INTRODUCTION: History. Why use VHDL ? Hardware design construction, design levels,
HDLs Hardware simulation and synthesis. Using VHDL for design synthesis, terminology.
PROGRAMMABLE LOGIC DEVICES :Why use programmable logic ? What is a
programmable logic device ? Block diagram, macrocell structures and characteristics of PLDs
and CPLDs. Architecture and features of FPGAs. Future direction of programmable logic.
BEHAVIORAL MODELING:Entity declaration, architecture body, process statement, variable
assignment, signal assignment. Wait, If, Case, Null, Loop, Exit, Next and Assertion statements.
Inertial and transport delays, Simulation deltas, Signal drivers.

signal assignment, Multiple drivers, conditional signal assignment, selected signal
assignment, block statements, concurrent assertion statement, component declaration,
