WebOne limitation in VHDL-1993 is that hexadecimal bit-string literals always contain a multiple of 4 bits, and octal ones a multiple of 3 bits. You can’t have a 10-bit hexadecimal bit-string literal, or one containing values other than 0, 1 or _, for example. In VHDL-2008, bit string literals are enhanced: they may have an explicit width, WebJun 7, 2011 · with VHDL 2008, there are to_string () (and to_hstring () ) functions declared for all types.

WebOur `line` variable (`L`) is an access type - a pointer to a string. We need to get at the memory where it is pointing. We do this by _dereferencing_ the pointer. This is done in VHDL by adding `.all` to our `line` variable `L`. And, finally, we just need to … WebCAUSE: In a VHDL Design File at the specified location, you used an aggregate for a record type object.
