ABSTRACT:
One use for delay adjustment circuit (32), coarse-grain delay offset circuit (34), and fine-grain delay synthesis circuit (36) may be as part of a delay replication circuit (30) used to replicate the frequency versus voltage behavior of an integrated circuit (29). Also, a circuit (30) and method for determining optimal power and frequency metrics of integrated circuit (29) is also described. In addition, a method for determining programmable coefficients to replicate frequency and supply voltage correlation is described.
