I have a problem about simulating OSC with hspice.

The netlist are as follow:
.tran 0.01u 15u

With this netlist,it works better and Avanwaves could show the the right waveform.
But when changing it to".tran 0.001u 15u",or altering "0.01u" into anyother value,it also works better,but Avanwaves could not show the the right waveform.

That's why?Would you tell what's the reason.
 

Hi,

Whatz the size of *.tr0 file in case of .tran 0.001u 15u?

u can try less value for stop time !!

If U wnt 2 simulate upto 15u then you can try multi point transient analysis

.TRAN tstep1 tstop1 <tstep2 tstop2 ...tstepN tstopN>

Hope this helps.

Thanx,
 

what is the frequence of your circuit?
