i am a new user of quartus,now there is a warning when compilation.
:LATCH primitive ... is permanently disabled".
i do not understand the meaning of that.
though i've used the quartus help,but...ha~ha~...
the ex. code
reg [15:0] a,d;
reg [15:0] b=0;
reg [15:0] c=0;
reg [3:0] state=0;
always @ (posedge clk)
begin
if(state <6)
begin
state <=state+1;
end
else if(state ==6)
begin
state <= 0;
end
else begin end
end
always @(state)
begin
case(state)
1'd0:begin
a=b-c;
end
2'd1:begin
d=a+b;
end
default:begin end
endcase
end
