Strange error in ADS's schematic simulation

[alexneverhurts]

My project file is huge since I did everything in one project, so I can't upload the project until I figured out a way to separate a single layout design, together with the associated layout file, substrate file, and simulation data nicely, and I do need help for this.

Therefore, let me just quickly explain this error message, just in case anybody is familiar with it.

I had a layout design, simulated it, got the s-parameters, and everything went smoothly without an error. Then I created a schematic component of this layout, used the simulated data. And I made a simple circuit with multiple such component connect in series, and measured s-parameters. It worked before, but when I changed the layout's geometry, re-ran layout simulation, re-created the component model, and re-ran the schematic simulation again, it gave me the following error message:

Invalid citi-data in the Layout Component ModelDatabase
Fatal error occurred while evaluating model 'MomCmpt', instance 'XXX'

(XXX is the name of my layout component)

I tried other layout components in the schematic, and they worked, so I'm totally confused here. I'll try modifying my design's geometry a little bit and re-run it to see if this error goes away.

Thanks!

You can try delete previous database and do not add the last simulation result when updating your layout component. Or copy the problematic layout in momentum into a new design and re-create your component. It worked for me in the past.

Each time when you do the modification in layout, you need to repeat the process of momentum-->component--->create/update and delete the old design simulation results.
The same message will be displayed by the tool when ever you create a schematic model from layout.
