Just (out)comment the vary lines which you don't want to be varied in the STATISTICAL Section of the model file (s. slide 11 of the above linked tutorial).
you mean i have to manipulate (fix) monte-carlo library in PDK???
is it possible to do monte-carlo simulation with swept variable??? (cadence 5.14 version)
Same as with any other parameter: give it a name, and write this 'name' where it should take place for your delay (e.g. in a vsource).
Vxxx n+ n- PU[LSE] [(]v1 v2 [[B]td[/B] [tr [tf [pw [per]]]]] [)] + [PERJITTER=val [SEED=val]]
Edelay in_delay 0 DELAY in 0 TD='td1' $$ signal "in_delay" is the "in" signal delayed by TD='[B]td1[/B]' + where [B]td1[/B] is your parameter to be swept.
