how to show a number in output text?

[Amit]

Hello group,

I'm learning to write a testbench so in part of the code I increment
a variable to count number of errors during simulation.

now, I need to know how I can print out a message showing number of
detected errors as following:

Found n error(s).

where n is the value in the counter variable.

Any help is appreciated.

p.s. I thought using & to concatenate would work but no

report "Found " & err_cnt & " error(s)" !!!! (wrong)

Concatenation works perfectly ... on strings, but err_cnt isn't a
string.

What you need depends on the type of err_cnt.
If it is integer, simply
report "Found " & integer'image(err_cnt)  & " error(s)"
will do.

Currently what you have to do is (as others have noted):
report "Found " & integer'image(err_cnt) & " error(s)"

IN VHDL-2008 (which some vendors are starting to look at) you can do this:

report "Found " & to_string(err_cnt) & " error(s)"

The "to_string" function is overloaded for EVERY type, so you can use it
on STD_LOGIC_VECTOR, UNSIGNED, Boolean, etc...

Thanks to all for your comments and help.
