Hello,
i have a counter which is 27 bit long.
signal counter : STD_LOGIC_VECTOR(26 downto 0);
Is there a "better" way to reset than counter

Martin,
If your signal "counter" is declared as an integer with a valid range you can then use a reset as shown:
signal counter : integer range 0 to 67108863 := 0; ... if reset = '0' then signal counter Hello,
Allan & Jason B. show the typical ways; alternatively, if you are using numeric_std, you could write:
counter
Personally, if I'm doing a counter I would use an unsigned type (or even an integer!) rather than "casting" to std_logic_vector all the time. After all, what you're representing is a number...
Cheers, Martin

Hi,
Here's a different but similar question: Is there a better way to do the following (vector extension):
signal A,B: std_logic_vector(10 downto 0); signal X: std_logic_vector( 7 downto 0);
