Abstract
A method and apparatus for improving the retiming of a circuit. The invention 'tricks' a conventional retiming engine so that the retiming engine will correctly and consistently retime the circuit. Specifically, the present invention adjusts gate delays to account for the fact that registers in the circuit may be moved during retiming. The present invention also includes a methodology for choosing a preferred register from a technology library. Lastly, the present invention also adjusts the clock period of the circuit to account for the fact that the retiming engine assumes a clock-to-state of registers in the circuit to be zero when this is not always the case.
