When initializing your floorplan design in Innovus, point the tool to your physical LEF files:

If you specifically need to practice on advanced nodes (45nm or 7nm predictive technologies) for academic simulation without fabrication intent, these predictive, non-manufacturable libraries are free to download online without an NDA. Integrating the Library into EDA Toolchains

Visual symbols used if you are instantiating gates manually within a schematic editor.

Transistor-level schematics used for circuit simulation and Layout-versus-Schematic (LVS) verification.
