News:

Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.

Transient Analysis

 

In transient analysis, I am getting a strange oscillation in my circuit that I know should not be there. Also, the oscillations are very jagged. What can I do about this?

 

Click on the menu sequence Scope/View/Data Points. This marks the actual data points that were calculated during the simulation. If there is a data point at the extremes of these oscillations, but none in between, these oscillations are probably due to trapezoidal integration error. You would need to tighten the numerical integration for this simulation. This may be done by either decreasing the Global Setting Reltol or by decreasing the Maximum Time Step value available in the Transient Analysis Limits dialog box. This will force Micro-Cap to take more data points which should get rid of the oscillations.
