ADEXL Monte Carlo Simulation Error: no statistical data generated for the test

[ranran19870222]

Hey all, I am encountering a problem when running Monte Carlo simulation in ADE XL. I want to use Monte Carlo mismatch simulation to find out the achievable IIP2 of a passive mixer at each corner (typical fast and slow). I am using virtuoso 6.1.4 and IBM cms9flp design kit. At the end of the running it gives the warning as follows:
ADEXL-5052: Monte Carlo run stopped because no statistical data generated for the test: XXX
1. In the output setup, I did add a scalar expression of IIP2, but it is a little bit complicated because my in/output signal is current. I have IIP2=ipn(hb2dBm hb1dBm 2 1), where I substitute hb2dBm and hb1dBm with dBm version of hb1 and hb2 where
hb1=harmonic(i("/V14/PLUS" ?result "sweephb_hb_fi-sweep") list(-1 0 1)) ---- fund
and hb2=harmonic(i("/V14/PLUS" ?result "sweephb_hb_fi-sweep") list(0 -1 1)) ---- 2nd order harmonic
2. For the corner setup, I turned off the process variation switch, customized the model file of design.scs for each corner and included them in the corner setup window. I also chose method "All" for Monte Carlo setup.
I am guessing the problem comes from step 1 with the expression for IIP2, but I dont know exactly where because it worked well for single simulation in ADE L.. and it is a scalar. Anyone has experience on this? Any help will be really appreciated

Hi,i am also getting same problem in IC 6.1.5 could you help in this regard...
