polarity of uTsu in Timing analyzer

I've a bit confused about the polarity of uTsu in Timing analyzer. As indicated in the table the uTsu is positive while in the timing diagram it is negetive. Which polarity of uTsu is correct and why...

Hi,

I received the feedback. This is not a bug.

POSITIVE uTsu:

-------------------------

- *Positive* number on waveform display

- Signal must arrive *earlier*. Therefore, the arrow will go *left* on waveform display, and you will see a *negative* entry in the required time calculation section of the timing report

NEGATIVE uTsu:

-------------------------------------------------------

- *Negative* number on waveform display

- Signal can arrive *later*. Therefore, the arrow will go *right* on waveform display, and you will see a *positive* entry in the required time calculation section of the timing report

Thanks.
