How to Use This Course
Study order, prerequisites, and signoff posture for STA learning.
Study order
Start with Constraints & SDC — bad constraints invalidate everything downstream.
Learn delay graphs and how to read report_timing before MMMC.
Study variation and SI before aggressive ECO.
Use interview pages to practice corner/mode/view narration.

CORNER/MODE/VIEW -> PATH GROUP -> METRIC -> ARTIFACT -> ECO -> REGRESSION
1. Which scenario (corner/mode/view)?
2. Which path group fails (reg2reg, in2reg, etc.)?
3. What is WNS/TNS and setup vs hold?
4. Cell vs net delay on critical path?
5. Constraint bug, view mismatch, or real path?
6. What ECO and what regression matrix?
