multisim解决timestep too small 仿真错误

Change RELTOL to 0.01% (Relative Error Tolerance)
Change METHOD to “trapezodial” (Integration method)
Change ITL4 to 100 (Upper transient iteration limit)

1. For a complex circuit, try simulating portions at a time until you identify the problem area. Sometimes a particular part model will be the problem.

2. In the Analysis Options, change the simulation mode from Trapezoidal to Gear.

3. In the Analysis Options, reduce the values of all the tolerance limits by a factor of ten or so. This will reduce the simulation accuracy somewhat but may allow the circuit to converge.
