STA (Static Timing Analysis)

STA (Static Timing Analysis) is one of the most important area in Semiconductor chip Designing. Having an in-depth knowledge and exposure in STA provides opportunity in exploring and understanding how other domains operate to design chip. As expert say Timing and Performance is almost everything, STA turns out to be the single most important domain which collaborates with every other areas of chip designing.
