The key advantage of VHDL, when used for systems design, is that it allows the behavior of the required system to be described (modeled) and verified (simulated) before synthesis tools translate the design into real hardware (gates and wires).
Ključna prednost VHDL-a, kada se koristi za dizajn sistema, jeste da omogućava ponašanje potrebnog sistema da bude opisano (modelirano) i verifikovano(simulirano) pre nego što alati sinteze prevode dizajn u stvarni hardver (kapije i žice).
