UMC 0.18 corner analysis

I want to do corner analysis in umc 0.18 um technology in caadence

the model files required for umc are

modelFile(

'("/usr/local/cadence/umc/UMC_18_CMOS/../Models/Spectre/MM180_DIODE_V113.mdl.scs" "")
)

now there are two kind of files one containing 5 sections tt ss ff sf fs
and another type contains 3 sections
typ min max

for the first kind it is easy to determine which section to use in which corner
but for second type of files which section i should for which corner.
please help

typ, min & max are related to (delay) times (rise, fall, propagation), so by standard, use
typ for tt, sf & fs corners,
min for ff ,
max for ss corner.
