Unable to get DC analysis

Hi,

I am trying to simulate BJT common ecmitter, JFET and MOSFET, input and output charactristics using esim but I unable to get the plots. please tell me how to see the results

if you are a part of today's workshop, please stick to the schedule given today, JFETs, MOSFETs are not part of today's workshop.

If not, post the cir.out file

you have not selected device modeling for BJT CE example

Dear Saurabhb,
I know that and I followed by selecting NPN model but still I unable to get simulation.

can you run another example and see if the simulation plots are coming?
