摘要
The function of logic cells may be changed by altering their metal routing. Logic cells altered in this manner may be used to correct, substitute, or otherwise alter the operation of logic blocks or scan paths without completely re-working an integrated circuit. The process may be referred to as an engineering change order (ECO) process. According to an exemplary process a buffer may be reconfigured to operate as a NAND gate, a NOR gate, or an INVERTER, for example, and may be configured to operate in a circuit in need of such a logic function.
