摘要
A computer-implemented method for modifying an original design of an integrated circuit in accordance with an engineering change order (ECO) design includes cloning complex logic gate having multiple logic functions with cloned logic gates in parallel with the corresponding complex logic gates in the original design and the ECO design and expanding each cloned logic gate to corresponding base functionality logic gates to provide an expanded original design and an expanded ECO design using the processor. The method also includes modifying at least a portion of the expanded original design to have a circuit topology that is the same as the expanded ECO design in order to have an input from the expanded original design to an output structure be the same as the input from the expanded ECO design to the output structure in response to an expanded original design input and an expanded ECO design input being non-equivalent.
