Abstract
- Nowadays, power is a dominant factor that constrains highly integrated hardware-systems designs. The implied problems of high power density, causing chip overheating, or limited power source in modern Internet-of-Things devices are most commonly dealt with the use of the dynamic power management. This method enables to use power-reduction techniques, such as clock gating, power gating, or voltage and frequency scaling. Since the adoption of power management is quite difficult in modern complex systems, there are new approaches evolving intended to simplify power-constrained systems design. We have also proposed such an approach, utilizing the system level of design abstraction and increased automation in the design process. In this paper, the proposed hybrid verification approach is described that represents an integral part of the suggested design methodology. It consists of formal and informal techniques, enabling the verification process to begin at the very early specification stage of the system development. Our approach helps a designer to create correct and consistent power-management specification and verifies whether the specified power intent is preserved after design refinement. The continuous automated verification steps can quickly find errors at early design stages and thus reduce the amount of design re-spins, which speeds-up the overall development process.
