Hi,
I've done a lot of FSM's, but today I can't make Quartus recognize mine as a FSM. The State Machine Viewer gives me a blank page.
I know it's not completed. There's missing the combinational always that sets the signals.
But as far as I know, it should give me the FSM "draw".
Don't care with the signals not being assigned.
Here's my code.
module CONTROL
# (parameter integer DATA_WIDTH = 16)
(
//Inputs
input wire clk ,
input wire rst ,
input wire start ,
input wire div0 ,
input wire lt0 ,
//Outputs
output reg enC ,
output reg enA ,
output reg enB ,
output reg rstC ,
output reg done ,
output reg newA
);
localparam IDLE = 1'b0 ,
MAIN = 1'b1 ;
reg STATE ,
NEXT_STATE ;
always @ (posedge clk, posedge rst)
begin
if (rst)
STATE <= IDLE;
else
STATE <= NEXT_STATE;
end
always @ (*)
begin
NEXT_STATE = STATE; //default
case (STATE)
IDLE: if (start)
NEXT_STATE = MAIN;
MAIN: if (div0 == 1'b1 || lt0 == 1'b1)
NEXT_STATE = IDLE;
endcase
end
endmodule
Hope someone can help me.
Thank You!
