A view is named FUNC_SS_RCMAX, but its actual configured objects point to an FF library and a different RC condition. What does the timing engine use?

From PDVerse MMMC Interview Masterclass · pdVerse Mentor Series

Direct answer

The configured object associations — not the human-readable name. The engine doesn't parse the name string for meaning; it uses whatever library, RC corner, and constraint mode are actually attached to that view object.

Mentor explanation

Names exist for engineers, not for the analysis engine. A name like FUNC_SS_RCMAX is a convenience — a hint meant to help a human quickly recall what a view is supposed to represent. But naming a view correctly and configuring it correctly are two separate actions, and nothing in the tool enforces that they stay in sync. If someone renames an object, copies a script and forgets to update an association, or reuses a delay corner by mistake, the name becomes actively misleading while the underlying analysis proceeds exactly as configured — silently, with no error. Never take a name as proof. Trace the actual object references before trusting what a view represents.

Tool check

Cadence or equivalent scenario flowreport_analysis_views (or scenario inventory report)

Inspect attached library set, RC corner, and constraint mode rather than trusting the name.

Key takeaways

  • The configured object associations — not the human-readable name.
  • The engine doesn't parse the name string for meaning; it uses whatever library, RC corner, and constraint mode are actually attached to that view object.
