I am new to PSPICE as well as the community and i'm trying some circuits given by my professor for an assignment. I've completed most of them which helped me in understanding how the software works but i'm stuck at this part and i can't find out what's wrong. The message i get when trying running the simulation is:
*Analysis directives:

The simulation is a parametric analysis with the VAMPL of the AC source as a global parameter and the circuit is this:
The JBreakN is modified with the parameters:
.model Jbreakn NJF (Beta=550u Rs=1 Rd=1 Betatce=-.5 Lambda=10m Vto=-3.44

+ N=1 Xti=3 Alpha=10u Vk=100 Kf=1E-18 Af=1)
I am sorry if the post is too long i am trying to give as much information as i can.
Thanks in advance to anyone answering.

I would like to add that the more information you write, the better. So no, its not too much information, there is just the right amount! :)
The VSIN source has a parameter called "AC" which it looks like you have turned off, so its not displayed on the schematic(you probably deleted it). You need to assign a number to that parameter, else you get this error.
This parameter sets the phase shift. You can just set it to 0.
Extra:
So its actually a little quirky. When you first add the source to the schematic, and don't alter the
AC
parameter, it is assigned a default value (0) and it will simulate fine. But if you open the property, and even though you don't write anything in the field, and click OK, it will assign<AC>
as the value to the parameter. It will therefore give an error next time you run the simulator, as<AC>
is not a valid value..
