What is an analysis view?
From PDVerse MMMC Interview Masterclass · pdVerse Mentor Series
Direct answer
An analysis view is the complete, named timing world an STA engine actually analyzes — built by pairing one constraint mode (the timing intent) with one delay corner (the cell-plus-wire condition). It's the object where "what is the chip doing" finally meets "under what condition.
Mentor explanation
Everything earlier in the flow — modes, libraries, RC corners, delay corners — exists to feed this one moment. A constraint mode alone has intent but no physical condition. A delay corner alone has a physical condition but no idea what behavior it applies to. Only when you combine them into an analysis view do you get something STA can actually run a full setup or hold check against. And even then, as you'll see in the next question, just creating that view isn't the end of the story.
Example or conceptual chain
Constraint mode (intent) + delay corner (cell and wire condition) -> analysis view.

Key takeaways
- An analysis view is the complete, named timing world an STA engine actually analyzes — built by pairing one constraint mode (the timing intent) with one delay corner (the cell-plus-wire condition).
- It's the object where "what is the chip doing" finally meets "under what condition.
