Explain the concept of a Clock Divider Circuit? Write a VHDL
code for the same?

Answer Posted / senthil

I am using the Mr.Suriya code with little modification.

ENTITY CLK_DIV IS
PORT(CLK: IN STD_LOGIC;
NEWCLK:OUT STD_LOGIC);
END CLK_DIV
ARCH BEH OF CLK_DIV IS
VARIABLE COUNT:INTEGER:=0;
BEGIN
PROCESS(CLK)
BEGIN
IF CLK='1' AND CLK'EVENT THEN
COUNT:=COUNT+1;
IF COUNT=8000000 THEN
NEWCLK<= '1';
COUNT:=0;
ELSE
NEWCLK<= '0';
END IF;
END IF;
END PROCESS;
END BEH;

Is This Answer Correct ?    12 Yes 12 No
