KNOW MORE ABOUT VLSI DESIGN

	VLSI Design today is the most happening field in Electronics. This is a highly specialized field that has the power of integrating billions of transistors on a Silicon Chip.
	To design a chip we usually write a code to a chip. These are of two types :ASIC and FPGA (mostly).ASIC stands for Application specific Integrated Circuits(ASIC) are a specialized integrated circuits which are programmed and reprogramming is not possible. Coming to Field Programmable Gate Array (FPGA) these are the integrated circuits which can be re-programmable depending on the application.
	There might be a question ,how these integrated circuits are programmed?
	The answer for this is ,there are two hardware descriptive languages through which the ICs can be programmed.They are VHDL and VERILOG HDL.
	VHDL stands for V(very high speed integrated circuit)Hardware Descriptive Language and VERILOG Hardware Descriptive Language. These two languages are used to program an IC.
	VHDL is intended for describing and modeling a digital system at various levels and is an extremely complex language compared to VERILOG.
	Most of the FPGA chips are designed using VERILOG in present days .
	So everyone who are interested can go through VHDL and VERILOG.
	One of the best book to learn VHDL for beginners is CIRCUIT DESIGN with VHDL by volnei A.Pedroni
	For VERILOG one among the best books is DESIGN Through VERILOG HDL by T.R.PADMANABAM and B. BALA TRIPURA SUNDARI.
