SDF Generation under Cadence Encounter EDI

Recently I've been doing an experiment with only one lib and one SDC, which means I only have one analysis view (typical). However, after calling write_sdf to generation the SDF, I'm surprised to see the SDF contains MIN and MAX delay, rather than showing only TYPICAL delay for each path. What's stranger is that MIN delay is not the same as MAX delay, and sometimes MIN delay are larger than MAX delay. I'm a little confused because I only have exactly one analysis view.

I loaded the same design to ICC and write sdf. ICC's sdf gave me 3 identical delay values of min:typ:max for each path, and this is what I expected.


I've seen someone posted somewhere that it may be the problem of OCV or si-aware, but it still occurred after I turned OCV or si-aware to OFF.

Can some EDI pros give me a hint?

Thanks!
