Assertion Violation Report Strings inc. Signal Values

[daveob]

I'd like to include values in the Report strings of my testbench assertion violation checks. Something like this:

	signal min_acq_time : TIME := 500 ns;

	assert (cnv'last_event >= min_acq_time)
		report "Aquisition time (" & cnv'last_event & ") is less than minimum acquisition time (" & min_acq_time & ")."
		severity warning;

Is it possible to convert STD_LOGIC signal values or TIME into a string to append to the Report string?

Thanks all.

Hi,

For your time or std_logic you can use the image function:

report "My std_logic value is " & std_logic'image(<name>) & " at time " & time'image(now);

Unfortunately not supported for std_logic_vector. Ben Cohen has written image functions to convert for example std_logic_vector to string:
