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.

14. Peripherals necessary for Microcontrollers / Microprocessor CPU : Central Processing Unit Input /Output Bus : Address bus & Data bus Memory : RAM & ROM Timer Interrupt Serial Port Parallel Port
