set Slew Rate in hspice

[deepakmd]

Hi,

My spec says that the input slew rate should be set to 80ps. I am using Pulse as input signal.
And slew rate is defined by 0.1 Vdd to 0.9 Vdd.

How to I set that in my spice file?

.measure trise trig v(in) val=0.6 fall=1 targ v(out) val=0.6V rise=1
.measure tfall trig v(in) val=0.6 rise=1 targ v(out) val=0.6V fall=1

.end
