Asynchronous NoC switch is proposed as a robust design to mitigate the impact of process variation. Circuit analysis is used to evaluate the influence of process variation on both synchronous and asynchronous designs. The delay and throughput variation are evaluated with different technologies. Although the asynchronous switch has large delay variation as compared to synchronous switch, high throughput is achieved under high process variation conditions. The throughput remains unchanged under high process variation conditions in asynchronous NoC switch, while the throughput of synchronous switch is rapidly reduced at the same conditions.
