Hi all,

I'm trying to use write() function to print out the contents of std_logic std_logic_vector type signals. Can anyone tell me how to do it?
I used to use report() function, but recently learned that write() can be used for printing things on a screen...
Thanks,

Gongdori
 

to use write to the screen, you need to write to OUTPUT.

write(my_line, some_slv);
writeline(OUTPUT, my_line);

but first of all make sure you have included std.textio.all and ieee.std_logic_textio.all before you can access the write functions.
I suggest reading a textio tutorial before you proceed.
 

Yup, you were right. I was missing ieee.std_logic_textio. It worked after I put that line in.
Thanks!
