newbe: how to print integer and real numbers?

[Schüle Daniel]

Hello,

quick question
I am simulating some simple VHDL code and need to
print integer and real variables.
Can someone give me examples or introduction pages to
basic IO in VHDL?
What I am also looking for is, kind of table
what type conversion function are provided and what are not
provided.

Thx in advance.

Hi Daniel.
i think that you can do it by using textIO statements. try this i hope
it will work.

Have a look into the package std.textio and see the available functions.
See, which parameters can be given to the available functions.

If you want to have ANSI C like text-I/O, have a look at
http://bear.ces.cwru.edu/vhdl/ Note that there is also a paper
describing the files.

Include STD.textio.all and use the image attribute to convert from
real/integer to string.

process
variable l : line;
variable r : real;
variable i : integer;
begin
-- real
write( l, real'image(r) );
writeline( output, l );

-- integer
write( l, integer'image(i) );
writeline( output, l );
end process;
