thanks for all ur comments. i hav finished modifying de traffic code and now it is really works.. sorry if i bother u all too much..
another question.. de prob that i facing now is that i want to generated a 1 Hz clock using clock divider method from the original crystal frequency of 33.333 MHz.. The FPGA board that I'm using is Apex20k EFC200-484 from Altera
de code is as below :
begin
cloc:process(clk)
variable cnt : integer range 0 to 16500000;
begin
if(clk'event and clk='1') then
if(cnt=16500000)then
cnt:=0;
clkout<='1';
else
cnt := cnt+1;
clkout<='0';
end if;
end if;
end process cloc;
I had compiled the code above.. and when i simulate for 2 seconds .. it took me overnite to finish .. anyone hav better idea than this method? thanks
