Ipulse wave in Cadence

[muffassir]

Hi all,

I am using Cadence 6.1.4

I want to have the pulse waveform that will start from 0A for 10ns and then rise to 15nA and stay for next 20ns.

When i am filling the option of ipulse instance : period= 30ns, pulsewidth=10ns.

what i get is the waveform that is ON for 10ns and OFF for next 20ns...I want to start my wave as OFF first then ON.
I see a option like pulsewidth=20ns.But the wave will start with ON.What i want the way to start from OFF position

Is there way to do that in Cadence.

Any help is much appreciated.

Thanks in advance..

i1 (in 0) isource dc=0 type=pulse delay=10n val0=0 val1=15n period=30n rise=1n fall=1n width=20n

You have dc, initial and pulse voltage levels in the instance
params. So set the DC and initial values to your OFF level
and your pulse value to ON level.
