Hi all,

Could anyone help to explain the terms of the total negative setup slack and the fast , worst negative setup slack in Astro tool,and what is difference between them?

Thanks
 

total is sum of all slack values..........while worst is the "WORST SLACK NUMBER "
 

Dear p_shinde,

Thanks for your suggestion,i copy a section of timing report from astro as the following

Code: 
ASTSUM:       Setup                             Hold                Num           Num
ASTSUM:       Slack      Num   Total                Slack   Num     Trans          MaxCap
ASTSUM:      -15.080    291    -2778.7            0.627    0         1366           473

I think -15.080 indicates the worst setup slack value, 292 is the total number of negative setup slack,and -2278.7 is sum of all negative setup slack,please correct me if i am wrong.

By the way,do you kown any about another iterm of "data-and-clock mixing",if yes, could you explain it in details?

Regards

thanks,
Prasad
