Introduction to VHDL

VHDL-abbreviation of Very high speed integrated circuit Hardware Description Language
VHDL resulted from the work done in the ˜70s and early ˜80s by the U.S Department of Defense.
In 1986,VHDL was proposed as an IEEE standard
Its roots are in the ADA language



Why Use VHD
L
Semiconductor devices dimensions have shrunk
Reduces design time for a large digital system because designer can model the circuit in a program that simulates the circuit operation
Avoids glitch which occurs in digital circuits
Unlike other programs its statements are inherently concurrent
To create sophisticated electronic products



Basic Building Blocks
ENTITY

It is the most basic building block in a design
Entity block describes the interface for the design which defines input and output logic signals of the circuit.


ARCHITECTURE

All entity that can be simulated have an architecture description
The architecture describes the internal operation of the design
Single entity can have multiple architectures
Three types: : Behavioral Modeling : Structural Design : Sequential behavior



How To Write VHDL Program

Active-HDL 4.2 software has been used for the design synthesis and simulation
The source code written using the normal TEXT editor,then saved as a VHDL file with '.vhd'extension and transferred to any of the VHDL design compiler.If the compilation shows no error(s),the file can be simulated,synthesized and implemented with FPGA

High-level


Source Code

library IEEE;
use IEEE.STD_LOGIC_1164.all;
ENTITY alarm_cntrl is
port(fire,temperature,alarm_disable,main_disable:in STD_LOGIC;
fire_alarm:OUT STD_LOGIC);
END alarm_cntrl;
architecture synth of alarm_cntrl is
begin
process(fire,temperature,alarm_disable,main_disable)
begin
if ((fire='1')and (main_disable='0'))then
fire_alarm<='1';
else
fire_alarm<='0';
end if;
end process;
end synth;
