It displays " Dly -3161.751 +67.442" when I use the "delay tune".
Why the first value is negative?
Also my status bar is always red, it didn't turn green, is there any setting I need to do to make it work?
For example: when the status bar display "Dly -3508.416 +15.38", I got the etch length is 13001.38, with the range of my constraints,
But the status bar didn't turn green, it is still red, and not in the middle either. The two Dly values doesn't help me either. What should I do?

It appears that you haven't finished routing the net in your last post. I don;t think you can actually get the length of tye net to be within your specs if it is not completely routed.
Thanks, for finished routing, the status bar doesn't turn green either, always red:
