Statisk tidsanalyse

Statisk tidsanalyse (STA) er en ikke-simuleringsbaseret metode til at verificere, at digitale kredsløb opfylder tidsmæssige begrænsninger (clock-frekvenser, setup/hold-tider, udbredelsesforsinkelser). Introduceret systematisk af Bhatnagar et al. i 1990'erne, beregner STA værste-tilfælde og bedste-tilfælde sti-forsinkelser ved at analysere logiske stier uden at simulere vektorer. STA er essentiel for moderne VLSI-design, muliggør hurtig tidsmæssig lukning før silicium og identificerer kritiske stier til optimering.
