Abstract
Methods for generating a design for logic circuitry using rotary traveling wave oscillators (RTWOs) are described. A plurality of RTWOs are is arranged into an array of rows and columns. Adjacent elements in the array are interconnected so that the clocks in adjacent element are phase synchronous. Clocked devices are placed along the signal path of each array element and each is connected to one of the multiple phases provided by the RTWO element. The logic circuitry, described by a netlist, is divided into a number of partitions and each of these partitions is mapped to one of the array elements. The logic circuitry of the partition is then placed within or about the element of the array to which the partition is mapped and the circuitry in the partition is connected between the clocked devices in the element of the array, according to the net list.
