In HSPICE, when the phase > 180 degree , the sotfward changes it and causes discontinuous plot as attached. How to avoid this situation? Thank you.
 

HI~! I saw your question. This graph isn't an error.

See your warning point, confirm peak to peak.

I think that graph tool change a 180 degree.
 

Thank digilog and hr_rezaee for explanation.
Is there any option in HSPICE to smooth the phase plot and prevent from discontinuouse edges? Otherwise, the plot looks strange though it is correct. Thanks.
 

you can in you .sp file delete the option:
.option post=2(may be post)
because you start a plot graphic processing,you can don't start it ,that's ok ,you can tyr
