10. VHDL is intended to serve three purposes: 1.Documentation: VHDL was originally used as a documentation language for describing the structure of complex digital circuits. As an official standard, VHDL provides a common way of documenting circuits designed by numerous designers. VHDL - Introduction

11. 2. Simulation: VHDL provide features for modelling the behaviour of a digital circuit, which allowed its use as input to software program that were then used to simulate the circuit’s operation. The 2 nd Purpose is…….

12. 3.Hardware Synthesis: In the recent years, in addition to its use for documentation and simulation, VHDL has also become popular for use in design entry in CAD systems. The CAD tools are used to synthesize the VHDL code into a hardware implementation of the desired circuit. And the 3 rd Purpose is….

13. FPGAMicrocontroller FPGAs are concurrentMicrocontrollers are sequential FPGAs flexible; one can add/remove the functionality Not possible in case of microcontroller Hard-wired connections make it most suitable for military applications and life- time is longer Microcontrollers keep changing with technology advancements so lots of re- work is required to be done to keep up with the changes Development time is longerReadily available peripheral make the development time shorter Less power efficientMore power efficient Difficult to solderCan be easily soldered on PCB Less time to market; less NRE costMore time to market; NRE cost is high Comparison of FPGA and Microcontroller Source: http://electrodesigns.net/blog/fpgas-microcontrollers/
