Hi, I'm new to SPICE. I'm using MacSpice to simulate a TL072 amplifier circuit. The following is my code:
OPAMP AMPLIFIER

As I simulated it, it prompt this message:
Circuit: OPAMP AMPLIFIER
Note: MacSpice converts spice2 'polys' to spice3 'B' sources, use 'listing physical expand' to inspect the result(s).
Note: Spice2 'poly' source translated at line 30.
Note: Spice2 'poly' source translated at line 31.
On line 52: .model op:jx pjf(is=15.00e-12 beta=270.1e-6 vto=-1)
Missing level parameter - using level=1
On line 57: .probe
Warning: .probe control card ignored.
I wonder what's wrong with the .probe? Do I miss something? And what does it mean "Missing level parameter - using level=1"? Can anyone please shed some light on these problems? Thanks in advance.
Btw, I got the TL072 model from Internet.
