GBA vs PBA in STA | Graph Based vs Path Based Analysis | VLSI Timing | SMS |

In this video, we clearly explain the difference between *Graph-Based Analysis (GBA)* and *Path-Based Analysis (PBA)* used in **Static Timing Analysis (STA)**. Both methods are used by STA tools like *PrimeTime and Tempus* to calculate timing delays and slews in VLSI chip designs. In this tutorial you will learn: • What is Graph-Based Analysis (GBA) • What is Path-Based Analysis (PBA) • Why GBA introduces pessimism • How PBA removes pessimism • Real-time STA examples of GBA and PBA timing reports • When STA engineers use PBA during timing closure We also explain a practical example using an *AND gate slew propagation example* and show how timing results differ between GBA and PBA. Note: in PBA I haved said 160 ps but it is actually 125 ps. This video is useful for *VLSI beginners, STA engineers, and physical design learners* preparing for interviews or learning real project concepts. If you are learning **Static Timing Analysis**, understanding GBA and PBA is very important for debugging timing violations. #vlsi #sta #vlsiengineering #asicdesign #asicdesign #asic #statictiminganalysis #gba #physicaldesign #pba #semiconductor #primetime #chipdesign #vlsiforbeginners #timinganalysis #timingclosure #stamadesimple
