9 years agoI redid my project with the MegaWizard IP Manager. Just like before the project compiles without any error, but i dont get a higher clock out of the PLL.
I used this code:library IEEE;
use IEEE.std_logic_1164.all;
use IEEE.numeric_std.all;
Entity Test9 is
PORT(
CLK : in std_logic;
LEDG : out std_logic_vector (0 TO 7);
DB1 : out std_logic_vector (0 TO 8)
);
end Entity Test9;
architecture Behavioral of Test9 is
Component PLL is
PORT(
inclk0 : in std_logic;
c0 : out std_logic;
locked : out std_logic
);
End Component;
SIGNAL CLK_100 : std_logic;
Begin
PLL_inst : PLL PORT MAP(CLK, OPEN, CLK_100 );
DB1(0) <= CLK;
DB1(1) <= CLK_100;
process(CLK_100)
Variable cnt : integer :=0;
begin
if (CLK_100'event and CLK_100='1') then
cnt:=cnt+1;
if (cnt=100000000) then
LEDG <= "11111111";
elsif (cnt=200000000) then
LEDG <= "00000000";
cnt:=0;
end if;
end if;
end process;
End Behavioral;
and LIBRARY ieee;
USE ieee.std_logic_1164.all;
LIBRARY altera_mf;
USE altera_mf.all;
ENTITY PLL IS
PORT
(
inclk0 : IN STD_LOGIC := '0';
c0 : OUT STD_LOGIC ;
locked : OUT STD_LOGIC
);
END PLL;

I get some Warnings like "No clocks defined in the Design", could this be the problem? Thanks in advance
