Verilog Code :

module COIN8(CUR_CNT,QUARTER,CENTS,DOLLAR,NEW_CNT);

//Count quarters ,CENTS and DOLLAR

input [7:0] CUR_CNT;

input QUARTER, CENTS,DOLLAR;

output [7:0] NEW_CNT;

reg [7:0] NEW_CNT;

// Block adds 25,50,75 and 10

always @ (CUR_CNT or QUARTER or CENTS or DOLLAR);

elseif(CENTS)NEW_CNT=CUR_CNT + 8\'d75;

else if (CENTS)NEW_CNT=CUR_CNT + 8\'d50;

elseif(QUARTER)NEW_CNT=CUR_CNT + 8\'d25;

elseif(CENTS)NEW_CNT=CUR_CNT + 8\'d10;

else NEW_CNT=CUR_CNT;
