Patent ID: 8638120

Claim:
A method for improving a success rate of an engineering design change (ECO) for an integrated circuit, comprising: identifying a plurality of spare latches within the integrated circuit; determining an input driver for each of the spare latches; determining a functionality of each of the input drivers and input/output pins of each of the input drivers; receiving the ECO for the integrated circuit; removing each input driver in response to receiving the ECO for the integrated circuit; replacing each input driver with a programmable gate array in response to receiving the ECO for the integrated circuit; programming each programmable gate array according to the ECO in response to receiving the ECO for the integrated circuit, the programming including programming each programmable gate array to include the functionality of the input driver being replaced and to include the input/output pins of the input driver, wherein each programmable gate array is programmed to include a higher driver strength than each of the input drivers that are replaced in response to receiving the ECO.
