Quiero ejecutar 2 módulos, uno tras otro con una señal de señalización
¿Qué cambios debo hacer en el código a continuación para los módulos? He usado delay_4 y multiplicar.
module iir_model(yout,temp1,win,clk);
input [3:0] win;
output [3:0] yout;
wire [3:0] yout;
input clk;
output [3:0] temp1;
wire [3:0] temp1;
delay_4 a1(temp1,win,clk);
multiply_4 (yout,win,temp1);
endmodule
delay_4:
module delay_4(data_out,data_in,clk);
input [3:0] data_in;
input clk;
output [3:0] data_out;
reg [3:0] data_out;
reg [2:0] counter=4'b000;
reg [3:0] temp;
reg carry;
integer i=0;
always @(posedge clk)
begin
i=i+1;
if(i==1)
temp=data_in;
if(i>1)
begin
if(counter!=4'b100)
begin
carry=temp[0];
temp=temp>>1'b1;
temp[3]=carry;
$monitor ($time," clk=%b, counter=%b ,temp=%b ,carry=%b,data_out=%b",clk, counter,temp,carry,data_out);
counter=counter+1;
end
data_out=(temp==data_in)?temp:4'b0000;
end
end
endmodule
multiplicar_4:
module multiply_4(z,x,y);
input [3:0] x,y;
output [7:0] z;
reg [7:0] t;
reg [7:0] z;
integer i,j;
always @ (x or y)
begin
z = 8'b0;
for(i = 0; i < 4 ; i = i + 1)
begin
t = 8'b0;
if(y[i])
begin
t[i] = x[0];
t[i+1] = x[1];
t[i+2] = x[2];
t[i+3] = x[3];
end
z = z + t;
end
end
endmodule
