What is the significance of "static timing analysis" (STA) in digital IC design, and what two main constraints does it check?
Correct! Well done.
Incorrect.
The correct answer is A) STA verifies signal timing throughout a chip meets requirements without simulating every input pattern; it primarily checks "setup" (signal must arrive before the clock edge) and "hold" (signal must stay stable after it) constraints
Correct Answer
STA verifies signal timing throughout a chip meets requirements without simulating every input pattern; it primarily checks "setup" (signal must arrive before the clock edge) and "hold" (signal must stay stable after it) constraints
STA analyzes all possible paths in a design (without needing input vectors) to ensure that data arrives at flip-flops within the required setup and hold windows relative to the clock, which is essential for closing timing on large designs where exhaustive simulation is infeasible.
