stb iprobe
Normally, stb or ac simulation proceeds at a DC operating point that is calculated at the start of the sim. But there are times when it can be useful to have the stb or ac analysis performed at some other operating point. One example might be the far extreme transient output voltage swing of an amplifier, where the gain can be quite degraded compared to its midpoint. This email tells how to set that up.
1. Confiigure the simulator to run both a stb (or ac) and a transient simulation.
2. Configure the transient simulation to end at the point in time at which you wish the ac analysis to be performed. (For example, at a time when you know the amplifier's output will be at full-scale.)
3. In the simulation window, go to Analysis-->Choose-->stb (or ac)-->options, and set "prevoppoint" to "yes". This tells the simulator to use the final value of the transient simulation as the operating point for the stb or ac simulation.
4. Run the simulation. The transient will run first, then the stb or ac will run using the final value from the transient as the operating point.

I m in inverter tutorial and getting error =
xi0.m1: Effective length is less than or equal to zero.
I changed the L & W to a certain range but it did not help.
Moreover for an another project i need to vary L & W to a certain range and see its graph simultaneously ... Can i do this? I know i can vary dc ac voltage and all that in analysys section but how can i do this in case of physical parameters such as Length and Width?
Can i vary the performance by changing any other parameter?
