The amount of complexity by which a system is viewed or programmed. The higher the level, the less detail. The lower the level, the more detail. The highest level of abstraction is the entire system.

Without abstraction, advances in semiconductor design would have stalled decades ago and circuits would remain about the same size as analog blocks. No new abstractions have emerged since the 1990s ...

During the past decade, several attempts to move verification to a higher level of abstraction have not delivered sufficient returns to systems designers or EDA vendors. The efforts by EDA vendors and ...
