NOTE: The primitive cells compiled through the simulator compile option -v or -y are treated as library cells.

NOTE: To skip cell instances, use the NOVAS_FSDB_SKIP_CELL_INSTANCE environment variable or the +fsdb+skip_cell_instance=mode runtime option. For example:

simv +fsdb+skip_cell_instance=1
