Post-Layout Simulation Error in Virtuoso with GPDK90: Undefined Model/Subcircuit

Hi,

I am having an issue during a post-layout simulation in Cadence Virtuoso, utilizing the GPDK90 technology. I have successfully created a layout and moved on to perform post-layout simulation. For this purpose, I created the "av_extracted" from Quantus. I then created the config Hierarchy Editor and set  "View to use"  as "av_extracted". However, upon running the maestro simulation with the "av_extracted" view I am getting some errors related to missing key model files. 

Could anyone provide some guidance on what might be causing this error and how to fix it?

Thank you in advance for your help.

The Error Snippet is:
