You can only use strings in test benches, not for synthesiable designs.

Strings are only really useful as constants because you have to set the length of them before you use them and they need padding:

signal my_string : string(1 to 6);

my_string <= "Hello"; --this is too short
my_string <= "Hello "; --fits

Best to use a line type - this is a pointer to a string. You can use the write functions to write stuff to it.
