Several factors such as process variation, noises, and delay defects can degrade the reliabilities of a circuit. Traditional methods add a pessimistic timing margin to resolve delay variation problems. In this paper, instead of sacrificing the performance, we propose a re-synthesis technique which adds redundant logics to protect the performance. Because nodes in the critical paths have zero slacks and are vulnerable to delay variation, we formulate the problem of tolerating delay variation to be the problem of increasing the slacks of nodes. Our re-synthesis technique can increase the slacks of all nodes or wires to be larger than a pre-determined value. Our experimental results show that additional area penalty is around 21% for 10% of delay variation tolerance.
