LM5158: simulation running time less than configure

Part Number: LM5158

dear

I want use LM5158 to output +/- 75V/25mA voltage from a input voltage 3.0V~5V. for evaluation the design, I do some simulation and try to evaluate the performance. however, the simulation is always slowly and stop simulation than I configured. is there any one in product line help to find root cause? thanks.

    Hi Bill,

    Thank you for using E2E forums, I am a bit confused by your question, could you elaborate what do you mean by "is there any one in product line help to find root cause?"

    Thank you

    Hi, Haroon

     please refer below figure. I want simulation running ~30ms. but the simulation just running ~2ms and then stopped.so I just get a ramp curve and could not check the stability output. the second issue is the simulation is very very slowly. do you have any idea to reduce simulate time. 

    thanks.

    Hi Bill,

    The simulation time can be reduced by making the system simpler but I guess apart from that nothing much can be done about that.

    Regarding the 2ms running and stopping, is there an error you are getting or warning of some sort?

    BR,
