Quantus: warning regarding separate field solver techfile with MEOL stack description

dontpanic

Hi! I am getting the following warning when performing Quantus extractions with the FS extraction mode:

WARNING (NEBULAM-135092): Design is using device stack extraction in 'TSMC finfet' node. Foundry is supposed to provide separate field solver techfile with MEOL stack description. With current techfile you are not going to get sign-off certified accuracy for nets connected to MEOL devices. If you do have FS technology file and still see this warning request Cadence support to recover accuracy.

Do I need to have some additional decks installed in order to use the FS extraction mode? I am using Quantus 18.2.1-s210 on TSMC 16FF+ PDK.

Thanks and regards, Jorge.

    Hi Jorge

    There should be a file named "_qrcfs_profile" in the QTS tech directory. You can contact TSMC to get the file.


    Best regards
