Integrated Circuits contains several transistors
fabricated on a single chip.

7. Classification of Integrated Circuits
Size classification( historical )
 <100 SSI 1963
100-3000 MSI 1970

8. 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 )

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

11. 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

12. 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

14. 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

15. VHDL
• Not case sensitive.
• Difficult to learn.
• Based on pascal & ada.
• Strongly typed.
VERILOG
• 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
Difference

16. 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

17. RTL verification wave form

18. 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 )

19. 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.

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