I am trying to use modelsim_ae with command line and use the built in libraries. But it doesn't find the -Lf Belowis the command line: But if finds none of the -Lf libraries?

Modelsim-Altera libraries have been pre-compiled for both functional and gate-level simulation. We should not compile the library files before running a simulation.

Document: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/qts/qts_qii53001.pdf#page=page2

Can you run the simulation without the need to compile the library?

Could you help to share the screenshot of your current modelsim-ae GUI with the library on the left-hand side?
