PSS Analysis Error

Hello All,

I am trying to design and simulate a LNA using Virtuoso IC6.1.5.500.1 32

While simulation using "PSS" as analysis, I am getting the following error.

ERROR (SPCRTRF-15177): PSS analysis doesn't support behavioral module components with hidden states found in component 'modnm_ahdl'

FYI... I am using AMS 350nm h35b4d3 technlogy and I am NOT using the PRIMLIBRF library; i am using the transistors from PRIMLIB library only.

 Do you think this may be the issue? 

Thanks!

 Best Regards,

Kashif
