What are the major files an MMMC timing run actually needs?

From PDVerse MMMC Interview Masterclass · pdVerse Mentor Series

Direct answer

At minimum: a netlist for connectivity, timing libraries for cell behavior, an SDC for timing intent, parasitic data for interconnect behavior, and an MMMC configuration that ties modes and corners together into views.

Mentor explanation

It helps to think of each file as answering one specific question, and MMMC as the layer that connects the answers. None of these files alone gives you a timing result — STA only produces a meaningful number once all five are present and correctly associated with each other.
