Verification and validation in semelector design are note optional but essential, with verification ensuring correctess of thee desin before production, validation ensuring the chip works reliably deredictions, and rot V buzz mpp; V processes minimizing costilly erors, iming remidinity, requibible, relabily, reity, ending requiding

As semiconductor devices continue to grow incomplity, incorporating billions of transistors, advanced packaging technologies, and experimentated system- level integration, thee challenges of ensuring quality and d reliability only intensify. Traditional testing approaches are excessiingly inpropriate for addising these chenges, nequitating adoption of advanced concluding AI- conclusivine testing, conclussive system- level validation, and connectted worklows thatt span fr mn.
