2. VLSI VLSI stands for Very Large Scale Integration.This is the field which involves packing more and more logic devices into smaller and smaller areas. And it is the process of creating an integrated circuits (IC) by combining thousands of transistors into a single chip.

3. VLSI CHIP

4. HISTORY Vlsi introduced by INTEL in 1970’s.

5. TYPES OF VLSI (ICS) There are some type on the basis of no. of transistors:- SSI MSI LSI VLSI ULSI

6. VLSI DESIGN FLOW A design flow of VLSI is the sequence of processes or steps involved in the making of an integrated circuit(IC).

7. VLSI DESIGN FLOW

8. APPLICATIONS OF VLSI Daily life Applications:- Refrigerator Calculator Water purifier Music player Smart watch Air conditioner Pen drive Toaster Dish washer

9. IDEAS Any thing we needs chip Microprocessor Microcontroller Memories Printer Mobile Digital security lock

10. ADVANTAGES Reduces the size of circuits. Reduces the cost of the devices. Increase operating speed of circuits. Less power consumption. High reliability. Occupies less area.

11. CMOS TECHNOLOGY CMOS inverter circuit consists of two MOSFETS ( NMOS and PMOS ) series such a way that the P-channel device has its source connected to +Vpn and the N-channel device has its source connected to the two devices are connected together connected together ground. The gates as the common input and the drains are as the common output. CMOS has the greatest complexity and lowest packaging density; however, it has important advantages of high speed and much lower power dissipation.

13. MICROWIND SOFTWARE Microwind software is used for layout design of various circuit. Microwind is a windows tool for designing and simulation microelectronic circuit at layout level. Process diffusion, poly-silicon pads, deep submicron CMOS design and n-well process.

15. CMOS LAYOUT Layout is drawing the masks used in the manufacturing process. so at the end of the day, foundry is going to create different mask on the basis of layout which designer has prepared. so from foundry side, it doesn’t matter in which seqence you have design the layout/mask.

17. HDL HDL stands for hardware description language. The current trend is to move away from proprietary HDLs and towards the two leading standards, VHDL and Verilog HDL. VHDL stands for VHSIC Hardware Description Language. It can describe the behavior and structure of electronic systems.

18. XILINX SOFTWARE XILINX ISE(Integrated Synthesis Environment) is a software tool produced by XILINX for synthesis and analysis of HDL designs, enabling the developer to synthesize(compile) their designs, perform timing analysis, examine RTL diagrams, simulate a designs reaction to different stimuli, and configure the target device with the programmer.

19. MODELING STYLE There are three modeling style for vhdl programming in XILINX:- Data flow Behavioral Structural

20. Vhdl code for and gate Library IEEE; use IEEE.std_logic_1164.all; entity andgate is Port(A: in std_logic; B: in std_logic; Y: out std_logic); end andgate; architecture dataflow of and gate is begin Y<= A and B; end dataflow ;
