Automatisk Testmønstergenerering

Automatisk Testmønstergenerering (ATPG) er den automatiserede oprettelse af testvektorer, der detekterer fabrikationsfejl i digitale kredsløb. ATPG, der blev banebrydende af Roth i 1966, finder systematisk input, der gør "stuck-at"-fejl observerbare ved output, hvilket muliggør omfattende fejldetektering. ATPG er afgørende for halvlederfremstilling: høj testdækning sikrer, at kun gode chips sendes ud, og identificerer problemer i fremstillingsprocessen.
