complexity
Novel techniques are required to cope with the ever-increasing complexity of digital systems and to utilize the integration densities offered by the advancing submicron fabrication technologies.abstraction
Abstraction is a useful way to deal with complexity. The OO paradigm allows higher abstraction than the behavioral level already provides.maintenance
Maintenance requires a long-term, as well as consistent and comprehensible, design & documentation in order to ease future modifications.
time-to-market
Object-oriented hardware modeling helps to fulfill the great demands on the design quality in terms of efficiency (power, speed, and area trade-off), testability, and correctness.Also the higher abstraction of object-oriented modeling allows easier validation of systems before fabrication. This avoids design iterations and helps to meet the market window.
