incmprehensible error

--- Quote Start ---

Hi !!

When i compile my programm, I have these errors :

My programm consists to a variable control_2 (std_logic_vector (15 downto 0)) which count up to a constant value . When this value is egal, control_2 is initialized to 0 and count up a new time, etc...

The constant can be 4 values defined by the position of a commutator (hardware).

Here I don't understand all these errors, and more even if my constant et control_2 is always 16 bits, sometimes i don't have these errors sometimes i have. It depends the value of the constant.

An exemple :

Here divide_2 is the constant. The values of divide_2 generate or not the compilation errors.

Why if for 8000Hz my value is "000000001101101" I have these errors?

And why for this case if my value is "000000001111101" I don't have errors...? The compilation is ok and my outpout is ok.

Please Help me...:confused:

Hi,

your post is also a little bit confusing. You posted that your compilation isn't successful, but later on you wrote that the compilation and your output is ok ?

BTW: What is the width of your signal, 16 bit ? You compare values are 17 bit or 15 bit ???

11101010011000000 17 bit

011000011010100 15 bit

000010011100010

000000001111101

000000000000001

Kind regards
