Please refer to the BJT_amplifier example provided with eSim.
reduce the sine amplitude to say, 100m. Reduce the step time to 100e-06
Adjust the values of resistors and capacitors. And please make sure that the global labels " in " and " out " are not floating i.e they are properly connected at the intended nodes.
