Abstract:
1. A method comprising: receiving input on a computer system indicating results of simulating one or more circuit designs used in an integrated circuit (IC), wherein the one or more circuit designs are susceptible to over-voltage conditions during operation of the integrated circuit; analyzing the simulation results on the computer system to determine that voltages on one or more circuit devices used in the one or more circuit designs exceeded a maximum allowable voltage during the simulation; computing on the computer system a respective scaled reliability rating for each of the circuit devices affected by the excessive voltages, wherein the scaled reliability rating for a given circuit device is dependent on a number of instances in the IC of the corresponding circuit design in which the given circuit device is used; and determining a reliability of the IC, wherein the reliability is based on the scaled reliability ratings for each of the circuit devices affected by the excessive voltages.
