Models for a liquidliquid phase transition

A method and apparatus for reducing contention in an integrated circuit during power-up. According to one aspect of the invention, an initialization circuit is included in an integrated circuit. In response to receiving Vcc, the initialization circuit generates a substitute clock signal and a substitute reset signal. The substitute clock signal and substitute reset signal are substituted for an off chip generated clock signal and an off chip generated reset signal during power-up until a predetermined condition is met. In response to receiving the substitute clock signal and the substitute reset signal, a plurality of circuits on said integrated circuit are initialized.
