transitions?

Subject: [IBIS] query regarding ramp functions
Hi all ,
I have doubt regarding the ramp down and ramp up functions.
While creating the .s2i i have set the simulation time to be 2.5ns.
The pulse signal thereby generated by s2ibis in rdn.spi is
PULSE(2.5 0 0 2.5e-11 2.5e-11 5e-09 1.01e-08)
.TRAN 2.5e-11 2.5e-09
However if i carry ahead with pulse and transient statement then for the
other ramp functions then in the final ibis file i get
Ramp]
| variable typ min max
dV/dt_r 0.61/0.13n 8.892e-21/-0.58n 0.82/89.36p
Now dT must be greater than 0 in a Ramp specification and thereby winibis
flags off an error.
So I needed to know how i go about this problem.
Looking forward for your comments.
Thanking you.
warm regards
arnab hazarika
