Static time analysis

What is Static Time Analysis?
Static timing analysis is a traditional type of frequency or clock rate analysis for an integrated circuit used in most computers and similar electronic devices.

In contrast to another method called delay calculation, which calculates a delay for each part of the circuit, static time analysis attempts to calculate the overall timing of the complete circuit, including individual delays. In contrast to other methods, static time analysis does not require any simulation.
Because static timing analysis provides some kind of generic assessment of the estimated frequency, there are variables that the process does not take into account. This includes temperature and voltage changes.

These types of physical problems can change the bottom line when it comes to the clock speed of an integrated circuit such as a CPU. Static timing analysis uses estimates called "corners" to predict certain outcomes.

A new alternative to regular static timing analysis is called statistical static timing analysis. Instead of using static or deterministic estimates, statistical statistical time analysis uses a range of probabilities. This can help technicians or others provide a better overall estimate of circuit performance.

There are also a number of automated timing analysis solutions that can help improve a company's ability to test products faster and more efficiently.
