okay, let's dive deep into static timing analysis (sta) for vlsi design, covering the concepts relevant to a 2023-2024 advanced vlsi design course, with a focus on the core principles and code examples. this will be a comprehensive guide.

*lecture 5: static timing analysis (sta)*

*1. introduction to static timing analysis*

static timing analysis (sta) is a method of verifying the timing performance of a digital circuit without requiring simulation. instead of actually running test vectors, sta analyzes the circuit's timing paths statically to determine if all timing requirements are met.

*why sta?*
*completeness:* exhaustive simulation is impossible for complex designs. sta provides a complete coverage of all possible timing paths.
*speed:* sta is much faster than dynamic simulation.
*early detection:* sta can detect timing problems early in the design flow, preventing costly redesigns later.
*sign-off verification:* sta is the standard sign-off method for most digital designs.

*basic concepts*

*timing path:* a sequence of logic gates and interconnects through which a signal propagates.
*clock domain:* a region of a circuit that operates with a specific clock signal. sta is particularly important at clock domain crossings (cdcs).
*setup time:* the amount of time a data signal must be stable before the active clock edge arrives for the flip-flop to capture the data correctly.
*hold time:* the amount of time a data signal must be stable after the active clock edge arrives to ensure the flip-flop captures the data correctly.
*clock skew:* the difference in arrival times of the clock signal at different flip-flops. skew can be positive (launch clock arrives earlier) or negative (capture clock arrives earlier).
*clock jitter:* the variation in the period of a clock signal.
*path delay:* the total time it takes for a signal to propagate ...
