Abstract
A method that determines the maximum number of logic cells that can be placed in a predetermined area on the base of an integrated circuit, and meet a voltage drop requirement. The method iteratively changes the logic cell spacing until the voltage drop requirement is made. This is done prior to the placement and extraction design phases as was done in previous methods. The predetermined area may be extrapolated across the base of the integrated circuit and meet the voltage drop requirements without the need to change the power grid, or to redo the placement and extraction phases. An integrated circuit designed according to the method, and an integrated circuit design system for using the method is also disclosed.
