ABSTRACT:
A method of optimizing timing of signals within an integrated circuit design using proxy slack values propagates signals through the integrated circuit design to output timing signals. For early mode timing analysis, the method sets an early proxy slack value to zero if the late slack value is less than zero. Otherwise, if the late slack value is not less than zero, the method restricts the early proxy slack value to a maximum of the early slack value and the negative of the late slack value. To the contrary, for late mode timing analysis, the method sets a late proxy slack value to zero if the early slack value is less than zero. Otherwise, if the early proxy slack value is not less than zero, the method restricts the late proxy slack value to a maximum of the late slack value and the negative of the early slack value.
