- 2. VLSI DESIGN
- 3. Contents• About Cadbridge semiconductor • IC & Classification • VLSI introduction & objective • VLSI design flow • VLSI application • VLSI companies in India • How can we placed in cadbrige semiconductor • IEEE paper implemented , improved & work on by me. • Conclusion
- 4. Cadbridge semiconductor • CADBRIDGE SEMICONDUCTOR is a emerging company in electronics field. • Corporate office - greater Noida . • Branch office - jalander ( Panjab) , jaipur ( Rajasthan) introduction Vision • To support a multicultural environment and make it our business to hire, inspire and develop the very best people in the industry, worldwide.
- 5. Area of work Work on • Memories • PCB Design • Digital security lock • Robots • Image processing • MATLAB • ARM KIT • AVR KIT Fature project • FPGA Board design • CPLD Board design • DSP KIT Design • microcontroller Arm kit Avr kit products
- 6. Integrated Circuits(ICs) What is Integrated Circuit? 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 3000 – 30000 LSI 1975 30000 – 1000000 VLSI 1980 > 1000000 ULSI 1990
- 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 .
