attribute signal name

Hi,
Can I access a std_logic signal attribute that is the signals name as a
string?
This isn't the 'image attribute is it?

Say for example I had a proceduure that did a check on various signals
and I wanted to 'report' the condition and the signal name; then I
would have to have two inputs, the signal and a string of the signal
name. (?)

Yup: my_signal'SIMPLE_NAME (or 'PATH_NAME or 'INSTANCE_NAME).

No. A signal-class formal parameter is a reference to a real
signal, so life is good for you. Try this:

library ieee;
use ieee.std_logic_1164.all;
use std.textio.all;

entity name_attrib is end;

architecture A of name_attrib is
signal SIG: std_logic;
procedure P (signal S: in std_logic) is begin
write(output, "simple_name = " & S'simple_name & CR & LF);
write(output, "path_name = " & S'path_name & CR & LF);
write(output, "instance_name = " & S'instance_name & CR & LF);
end;
begin
process begin
P(SIG);
wait;
end process;
end;

Yet more stuff that's easy in VHDL but the Verilog folk didn't
think of
