Master STA from Novice to Sign-off Timing closure. Learn Setup/Hold, SDC, OCV, PVT, LVF, MMMC, SPEF, TWF, Timing Reports
Have you ever wondered how companies TOP MNCs can guarantee that their chips, with billions of transistors switching billions of times per second, will actually work at the advertised speed? The answer is Static Timing Analysis (STA), and it’s the single most critical sign-off step in modern chip design.
What you’ll learn
- Understand the fundamental concepts of Setup Time and Hold Time, the core of all timing analysis..
- Learn to write essential SDC (Synopsys Design Constraints) for clocks and I/O paths..
- Confidently analyze and interpret real STA reports to find violations (WNS, TNS)..
- Grasp how timing libraries (.lib), parasitics (.spef), and On-Chip Variation (OCV) impact results..

Have you ever wondered how companies TOP MNCs can guarantee that their chips, with billions of transistors switching billions of times per second, will actually work at the advertised speed? The answer is Static Timing Analysis (STA), and it’s the single most critical sign-off step in modern chip design.
This course is a Basic, practical, straightforward guide to mastering STA from the ground up. We’ll skip the unnecessary jargon and focus on what really matters. My goal is to teach you the concepts and skills you’ll actually use in the industry, whether you’re designing an ASIC or an FPGA. We’ll explore why a timing path fails and, more importantly, how to read the reports to understand the problem.
By the end of this course, you won’t just know the theory – you’ll be able to confidently analyze timing reports and understand the impact of your design choices.
