A design structure for piggybacking multiple data tenures on a single data bus grant to achieve higher bus utilization is disclosed. In one embodiment of the design structure, a method in a computer-aided design system includes a source device sending a request for a bus grant to deliver data to a data bus connecting a source device and a destination device. The device receives the bus grant and logic within the device determines whether the bandwidth of the data bus allocated to the bus grant will be filled by the data. If the bandwidth of the data bus allocated to the bus grant will not be filled by the data, the device appends additional data to the first data and delivers the combined data to the data bus during the bus grant for the first data. When the bandwidth of the data bus allocated to the bus grant will be filled by the first data, the device delivers only the first data to the data bus during the bus grant.
