Your question is no more than very specific EDA vendor's Tool Play not Measurement Issues.

I don't know "IIM3". What is "IIM3" ?

First of all, do you understand definitions of HD3 ,THD, IIP3, IM3 correctly ?
How degree are you familiar with Cadence Spectre and ADE ?
How do you evaluate the above characteristics ? DFT using Transient Analysis or PSS(QPSS) ?
Can you write Ocean Script ?

See http://www.designers-guide.org/Forum/YaBB.pl?num=1220511510/0#0
If you understand definitions of HD3 ,THD, IIP3, IM3 correctly, you can evaluate them whatever analysis you use such as Transient, PSS(QPSS).

Your following question is also no more than very specific EDA vendor's Tool Play not Design Issues.
