Integrated Circuits(ICs)
What is Integrated Circuit?
Integrated Circuits contains several transistors fabricated
on a single chip.

Classification of Integrated Circuits

VLSI introduction : Objectives
introduction :
• A VLSI (Very Large Scale Integration) system
integrates millions of “electronic components” in
a small area (few mm2 few cm2).
Objectives:
design “efficient” VLSI systems that has:
• Circuit Speed (high )
• Power consumption ( low )
• Design Area ( low )

Vlsi design flow
1. idea (need) 2. specifications 3. design architecture 4. RTL coding
5. RTL
Verification
6. Synthesis7.Foundry8.IC Chip

1. Ideas
• Microprocessor
• Microcontroller
• Memories
• Printer
• Mobile
• Digital security lock
Any thing we needs chip

This is the crucial step as it will affect the future of
the product. Here, vendors may want to get
feedback from potential customers on what they are
looking for
• Instruction set
• Interface (I/O pins)
• Organization of the system
• Functionality of each unit in the system, and how to
communicate it to other units.
2.Specifications

3. Design architecture
• This is where the main work starts. With the help of
the specification sheet the target IC’s architecture is
decided and a layout for same is created by design
engineers using EDA tools.
EDA Tools :
• Synopsys – astro
• activehdl
• Xilinx - ise design suite
• Cadence - encounter digital ic design

4. RTL coding
RTL - register transfer level.
• This implies that the VHDL/VERILOG code
written based on the architecture describes
how data is transformed as it is passed from
register to register.
RTL coding tools
• xilinx ise,
• Vim,
• Emacs,
• conTEXT,
• HDL TurboWriter

VHDL
• Not case sensitive.
• Difficult to learn.
• Based on pascal & ada.
• Strongly typed.
• Case sensitive.
• Easy to learn.
• Based on c.
• Not strongly typed.
HDL – Hardware Description Language
ƒ
A programming language that can describe the
functionality and timing of the hardware.
Types of HDL
• VHDL ( Very high speed integrated circuit Hardware Description Language)
• VERILOG
• SYSTEM VERILOG
VERILOG
Difference

5. RTL Verification
RTL simulation and verification is one of the important
step. This ensures that the design is logically correct and
without major timing errors. It is advantageous to perform this
step, especially in the early stages of the design.
RTL verification tools
• Modelsim
• Finsim
• Verilog - XL
• TestBuilder
• Xilinx ise

6. synthesis
This is where the design now start to get physical. Logic synthesis
is a process by which the desired circuit behavior i.e. Register
Transistor Level is turned into a design in terms of logic gates
which drives the circuit or architecture.
Synthesis tools/kit
• FPGA (Altera,digiland,xilinx)
• CPLD ( altera , digiland )

FPGA KIT
Field programmable gate array (FPGA)
• It is a IC which can be be programmable by user to capture the logic.
• Capable to capturing 100,000 designed gates.

7.Foundry
The design is sent for Fabrication for mass
production to foundry .
