Abstract:
A method for designing an integrated circuit (IC) which contains a plurality of cells with interconnecting signal lines in close proximity, such that capacitive coupling among the signal lines is operable to induce a crosstalk noise pulse on at least one of the signal lines, the method comprising the steps of:forming a multi-dimensional noise lookup table for a cell used within the IC, wherein the multi-dimensional noise table relates a set of input noise pulse characteristics and a set of output loading characteristics to an output noise pulse characteristic of the cell; determining a first noise pulse on an input to a first instantiation of the cell; characterizing the first noise pulse to form a first noise pulse characteristic; and predicting if the first instantiation of the cell will propagate the first noise pulse by selecting an output noise pulse characteristic from the multi-dimensional noise table corresponding to the first noise pulse characteristic.
