Hi,

In DC, Total Negative Slack (TNS) is the total of all of your violations (negative value).

In ur TNS, there is Worst Negative Slack. Meaning, ur worst (or big) violation.

FYI, Design Compiler optimizes based on worst negative slack only, not on total negative slack.

Pls correct me if I'm wrong.

rgds,
 

DC optimisation is based on a Design Cost function which also uses WNS as one parameter.
