Abstract :
Resonant rotary clocking is a novel clocking technology for low power, high frequency integrated circuits. Rotary clock distribution networks are traditionally designed using regular array topologies of oscillatory rings. In this paper, the design of rotary clock distribution networks using a custom ring topology is investigated. Custom ring topologies permit reduced total wirelength for registers tapping onto the oscillatory rings, impacting overall power dissipation. A maze router based algorithm is developed for implementation of custom topology rotary rings. In experiments performed on UCLA IBM benchmark circuits, an improvement of 13.09% for register tapping wirelength is achieved on average.
