Hi,
you have found a bug in the annotator. As a work-around, set the path to
annotate: use --sdf=max=/=disp_value1.sdf
Also, the example was not complete. Try with this one:
library ieee;
use ieee.vital_timing.all;
use ieee.std_logic_1164.all;
entity disp_value is
generic (tipd_i : VitalDelayType01 := (0 ns, 0 ns));
port (i : std_logic);
end disp_value;
use std.textio.all;
architecture behav of disp_value is
begin
process
variable l : line;
begin
write (l, string'("tipd_i = ("));
write (l, tipd_i (tr01));
write (l, string'(", "));
write (l, tipd_i (tr10));
write (l, ')');
writeline (output, l);
wait;
end process;
end behav;
Tristan.
