This document provides an overview of VLSI and embedded systems. It discusses VLSI design flow including hardware description languages, FPGA and EDA tools. It also introduces embedded systems and discusses the differences between microcontrollers and microprocessors. Key aspects covered include VLSI integrating millions of components on a chip, FPGA's being reprogrammable after manufacturing, and embedded systems having dedicated functions often with real-time constraints.

3. Introduction to VLSI
An IC is a chip or die where many circuit
components and the wiring that connects them
are manufactured.
A VLSI system integrates millions of electronic
components in a very small area.

4. Generations of IC

5. Field Programmable Gate Array
(FPGA)


An FPGA is a semiconductor device that can be
reprogrammed after manufacturing.
Applications of FPGAs are:

Computer Hardware Emulation

Broadcast

Wireless Communication, etc.

6. FPGA Design

FPGAs can be reprogrammed to desired application or
functionality requirements after manufacturing. This
feature distinguishes FPGAs from Application Specific
Integrated Circuits (ASICs), which are custom
manufactured for specific design tasks.

7. VLSI DESIGN FLOW

8. VLSI Design Flow (contd.)


Design Architecture:
Designers can use different abstraction levels
for VLSI design:

9. VLSI Design Flow (contd.)
RTL Coding: HDLs



Stands for “Hardware
Description Language”.
A language that can describe
the functionality and timing of
the hardware.
Support for hardware
concurrency and time frame
are two main features that
distinguishes HDLs from other
programming languages.

10. Uses and Requirement of
HDL



It provides with concurrency constructs to
simulate circuit behavior.
Simulation for verification and synthesis.
It allows textual representation of how data
flows between register and how design
processes them.

11. EDA Tools


Stands for “Electronic Design
Automation”.
Commonly used EDA tools are:
Xilinx ISE, ModelSim,
Cadence, etc.

Used to compile, simulate and
synthesize the code written in
HDL

12. Introduction to VHDL

Stands for “Very High Speed Integrated
Circuit Hardware Description Language”
(VHSIC HDL).

It is an IEEE and ANSI STANDARD;
therefore, models described in this
language are portable.

Supports three design description
methods and can work with any
combination of them i.e., it allows mixed
type modelling.

13. Introduction to Embedded
Systems


An Embedded system is a special purpose
computer system designed to perform one or a
few dedicated functions, often with real time
computing constraints.
In an embedded system, there is only one
application software that is typically burned
into ROM. Example: Printer, Keyboard, etc.
