-*********************************************************

-* Design			:Seven Segment Decoder				*

-* Model Name		:SEVEN_SEG_DECODER					*

-* Modelling Style	:Structural Modelling				*

-* Language			:Verilog							*

-*********************************************************

-* Description:											*

-* This is an implementation of BCD to Seven Segment 	*

-* Decoder. The module takes 4 bit BCD input and converts*

-* it into equivalent sevent bit output which can be used*

-* to drive Seven Segment Displays. The design is made 	*

-* Common Cathode Seven Segment Display.					*
