Default simulator Error


Hi,
I am using ISE8.2.03i and its simulator is giving the following error

ERROR:Simulator:29 - at 0 ns : Index 19 out of bound 15 downto 0.

Does anyone can advice that how can I get rid of this error?

John

Read the error - it is self-explaining.

You have declared a signal with the range (15 downto 0) and you try to
access bit 19 - wich does not exist in this vector.
Because it happens at 0 ns - at the begin of the simulation - it may be
a problem of the rest value of your index variable.

The simulator is "always" right.

Try to make a minimal example. Try to eliminate everything, that is not
needed and try to find the location of the "error". You may post tThis
minimal example here, but I guess after searching for this "error" you
will find the reason for it.
