In this circuit an error is displayed. What may be the reason(s)? The error message is ' '

    These pins must be connected for successful simulation of this chip (SG3524). Look at datasheet of this devices and add appropriate connection on PIN 5 and 10. In case you do not intent to use these pins you may want to terminate these with high impedance.

    I read the datasheet after your reply. The circuit given here is taken from the datasheet. Here also these pins are kept unconnected.

    I also tried terminating these with high impedance but the output were not the desired ones.

    I needed to observe the output in steady state. But I couldn't find any steady state time domain analysis option. That's why I used transient analysis. I am confused about whether it will provide correct output or not. Can you ensure me about this.

    Transient analysis is right analysis type for such circuit and analysis goal. You need to keep simulation time long enough to achieve steady state value.
