Experience:

This Reddit thread discusses what to expect for a Marvell PD intern interview. Key topics to study include timing fundamentals such as setup and hold time, clock skew, and clock-to-Q delay, along with understanding how constraints are set up.

Candidates should be prepared to explain timing paths and violations.

Strong scripting skills, particularly in TCL (for tools like PrimeTime or Tempus) and Python for automation, are highly recommended.

A general understanding of the full Physical Design (PD) flow, especially where STA fits in and how timing closure works iteratively with place and route, is important.

MOSFET basics, including how delay varies with PVT corners and the impact of wire parasitics on timing, are also considered fair game.

The advice emphasizes showing the ability to learn and possessing the right foundation, rather than being an expert.
