How does these display work making the log report coloured for required word

[viveks2585]

Hi,

This is a UVM code which shows some display statements.

if ( fatal_count > 0 || error_count > 0 )
$display( "*** %s SIMULATION FAILED %s ***",
white_chars_on_red, reset_color );
else if ( warning_count > 0 )
$display( "*** %s SIMULATION PASSED (warnings=%0d) %s ***",
black_chars_on_yellow, warning_count, reset_color );
else
$display( "*** %s SIMULATION PASSED %s ***",
black_chars_on_green, reset_color );

First question is how does this make the log file to become coloured for a particular work and secondly how does this work.

Thanks,

That's not a good thing to see $display's in UVM code.

In any case, You'll have to look at the source code they are using that sends ASCII control codes to the log file that change the color of the terminal when viewed on a certain terminal window.

This is not part of the UVM, but there are user contributed packages to add coloring to your log files. Here is one example
