Why is the time step too small?

[Bhavesh]

For the attached circuit I am having an issue with a "time-step too small" message. How can I fix this? File is attached.

Hi,

To get this circuit to run without the "time step too small" error, select Simulate>>Interactive Simulation Settings>Analysis Options>>Customize>>Transient, change the method of integration from "trapezoidal" to "gear". 
 
For more information about this error please refer to the following knowledge base:
