string type conversion

[webb4789]

Anyone help with this?

In my test bench I want to enter expected bus values in hex and verify them against a STD_LOGIC_VECTOR type with an ASSERT statement.

If the string is of fixed length this isn't hard to do, but the problem arises when I try to write a hex2STD_LOGIC_VECTOR type_conversion routine for a string of arbitrary length. As string is unbound, the normal 'left type attributes have no meaning.

'left should work with any size vector (string)

if the input string is any length then your function may need a parameter that tells it what size std_logic_vector to return and what to do if the input string is too long or too short.
