Questions on initializing signals in QuartusII 4.1

[dairui]

I want to use the hardware primitives or some other way in QuartusII 4.1 to initiate signals in stead of using a reset signal.How can I achieve this?

I think you can directly assign a state to the signal when u define it.
eg.
signal abc std_logic := '1'

I think this should work in QuartusII 4.1. Altera had implemented this in Quartus II 2.1.

Try out & let me know

OR

You can also do
abc <= '1' when abc = '0';

cheers,

I'm sorry to tell u that the first solution u presented can not work because the default value of signal abc will be ignored by the compiler of QuartusII,and the actual requirements will not be met through the second solution.
In fact,I wanna initialize an array in my digital design.THe specific statements are as follows:
type configdatatype is array(0 to 31) of std_logic_vector(15 downto 0);
signal configdata:configdatatype:=(0=>x"0b0a",1=>x"0d0c",2=>x"0f0e",others=>"0000000000000000");
The default value of array configdata are mentioned above,and signal configdata will be variedaccording to the input signals' transition.How can I do to make it happen?
Tremendous thanks,

Hi,
Then you can try to initialize the array on reset.

for eg. if reset is low set the locations to respective values.
