questions:

1. why the "export" was not executed?

2. how to plot an expression from resultsdirectory?

what i am trying to achieve is do a DC followed by an AC within each MC run and nested with a sweep of a parameter.

appreciate any feedbacks.

I don't understand. In your original post, you had a sweep within monte carlo (sweeping EQ from 0 to 3 in steps of 1). That would do 4*100 simulations. In a later append, you said that you wanted the measurements at each value of EQ for each monte carlo point, so that's inherently iterations*sweep_points.
So what are you really trying to do?
Note that the actual number of invocations of the simulator will be dependent upon the setting of the "number of jobs" in ADE XL. With the corner sweep approach, the simulator will be invoked (at least) once per corner. With a sweep of 0:1:10, if the number of jobs is less than 11, you'll get 11 jobs each running 100 MC iterations - some in parallel if you have asked for more than 1 job. If you'd asked for 22 jobs, you'd get 22 simulations in parallel, each running 50 MC iterations, etc. This is assuming you only have a single test.
If you are trying to run 100 MC iterations total, but include the effect of varying EQ, you could always define a statistics block in an include file to define the variation of the variable EQ (maybe with a uniform distribution - maybe you vary another variable with a continuous uniform variation, and then set EQ to be the int(contVar) if it has to be an integer). That way you'd then include random values for EQ - although I'm not entirely sure that's terribly useful (it depends on what you really are trying to measure).
Regards,
Andrew.
