Abstract:
A method for repairing logic design includes inserting primary logic gates in a primary logic design path of a logic chip. The method also includes inserting alternative logic gates in an alternate logic design path of the logic chip. The alternate logic design path and the primary logic design path are coupled to multiple fuses. The potentially defective design is repaired by selecting between the alternate logic design path and the primary logic design path with the fuses when the logic design is defective.
