Cannot change timestep with function generator in circuit

[LnY_Designs]

There is a function generator (sin, 4kHz, 4Vp) in my circuit. I tried to change timestep in Interaction Simulation Settings but timestep didn't change at all.

Then I removed the function generator and timestep can be changed. Does anyone know why?

Hi there,

Thank you very much for your question. I suggest that check the wiring in your circuit first. If the wiring has been validated in the circuit then follow these steps:

1. Select Simulation=> Interactive SImulation Settings

2. Under Initial conditions select Set ot zero

3. Click the OK button

Check to see if the simulation now works. If not:

4.Select Simulation=>Interactive Simulation Settings

5.Check Set maximun time step(TMAX)

6.Select Maximum Time Step(TMAX) and change it from 1e-005 to 1e-003

7. Click the OK button

Hope this helps!
