2. Design a counter satisfying the following conditions: (20 points) a) Has a clock input. b) Has a four-bit data output. c) Has a reset input. Whenever reset-'1', the data outputs are set to zero; d) Has a load input and four-bit data inputs. When load -'1', the data outputs are set to synchronously e) Have one-bit control inputs. when control-0, the counter is counting between 0r8; w the counter is counting between 0r9; ) Reset has the highest priority, After clock signal, load has the second highest prioritya priority.

Explanation / Answer

module counter(clock, reset,control,load,in, out) ;

input clock, reset, control,load ;

input [3:0] in;

output [3:0] out ;

reg [3:0] out ;

always@(posedge clock )

begin

if (reset)

out=4'b0000;

else if(load)

out=in;

else

if(control)

if(out<8)

out=out+1;

else

out=0;

else

if(out<9)

out=out+1;

else

out=0;

end

endmodule
