VLSI TECHNOLOGY..

SCALING

Digital logic is implemented using transistors in integrated circuits

containing many gates.

Small scale integrated circuits(SSI) contain 10 gates or less.

Medium scale integrated circuits(MSI) contain 10-100 gates. Large-scale integrated circuits(LSI) contain upto 104 gates.

Very large-scale integrated circuits(VLSI) contain

>104 gates.

Improvement in manufacturing lead to ever smaller transistors

allowing more per chip.

>107 gates/chip now possible;doubles every 18 months or so

HARDWAREDESCRIPTIONLANGUAGE (HDL)

There are two popular HDLs:-

VHDL(Very High Speed Integrated Circuits

Hardware Description Languages)Developed by DOD from 1983

IEEE Standard 1076-1987/1993/200x

Based on the ADA language

Verilog

IEEE Standard 1364-1995/2001/2005

Based on the C Language

WHATIS VHDL

VHDL is an acronym for VHSIC Hardware Description Language (VHSIC is anacronym for Very High Speed Integrated Circuits).

Itis a hardware description language used in electronic design automation todescribe digital and mixed-signal systems such as fieldprogrammable gate

arrays and integrated circuits.

The language has constructs that enable to express the concurrent or sequential

behavior of a digital system with or without timing.

This language not only defines the syntax but also define very clear simulation

semantics for each language construct.

DESCRIBINGADESIGN

In VHDL, a design consists at a minimum of an

entitywhich describes the interface and an

architecturewhich contains the actual

implementation

An entity can be described using,

1. Entity declaration.

2. Architecture.3. Configuration

4. Package declaration.

5. Package body.


8/19

Entity declaration:

It defines the names, input output signals and modes of a

hardware module.

Architecture:

It describes the internal description of design or it tells what is

there inside design.

Configuration:If an entity contains many architectures and any one of the

possible architecture binding with its entity is done using

configuration.


9/19

CONTINUE..

Package declaration:

Package declaration is used to declare components,

types constants, functions and so on

Package body:

A package body is used to declare the definitions

and procedures that are declared in corresponding

package. Values can be assigned to constantsdeclared in package in package body.

ADVANTAGES OF VHDL

VHDL offers several advantages to the designer.

Standard language. Readily available tools.

Powerful and versatile description language.

Multiple mechanisms to support design hierarchy.

Versatile design reconfiguration support. Support for multiple levels of abstraction.

FUTURE ASPECTS OF VHDL.

VHDL describe the behavior is a fast growing industry and with

unbelievable future aspects.

Floating point multiplier VHDL future scope

16-bit microprocessor using VHDL.

CONCLUSION

I conclude that the VHDL language is more comprehensive andsimple.

As a knowledge of Hardware Description Language has

become a very important aspect for ELECTRONICS ANDCOMMUNICATION ENGINEERING students.

Moreover with the advent of new technology every 5 to 6

months, it has become very important to know the varioustechnology advancements happening in electronics field,

and for this the Hardware Modeling Language provide a very

convenient platform.

CONTINUE

Each and every component is simulated

individually, also CPU simulated using component.

All the component and CPU shows good results.

Waveforms are shown in the report, which showscorrect results.
