Im trying to bring in a load of file paths into a testbench via
generics (I use generics an an area for stuff other users are allowed
to modify). I really need an array of strings for the file paths
because I need to match the length to another generic that is an
array, otherwise the TB should fail.
Now I know I could easily do this with VHDL 2008 like:
type str_array_t is array(natural range <>
of string;
but lets assume for the moment that we cannot use VHDL 2008. am I
stuck, going to have to use a separate generic for each file path,
which makes the TB far more verbose because I wont be able to do a
loop to read in all of the files.
I thought about using an array of lines, but the problem with pointers
is that they have to be variables, and I would have to set the paths
up in a process. Ideally Id like to read the files before time starts.
Im guessing Im stuck, and this is exactly why they brought
unconstrained array elements into the language.
