Patent ID: 8078438

Claim:
A method for simulating a thermal resistance value of a thermal test die performed by a software program of a processor, comprising: determining a size of one of a plurality of heating blocks according to a temperature distribution of the thermal test die, wherein the step of determining the size of the one heating block according to the temperature distribution of the thermal test die comprises: providing a thermal resistance value R TTV of the thermal test die; providing thermal resistance values R heater for the plurality of heating blocks, and obtaining a relationship between the sizes of the plurality of heating blocks and the thermal resistance values R heater of the plurality of heating blocks; and setting a target value R Target to determine the size of the one heating block that matches the target value R Target ; setting at least one parameter for thermal performance testing, heating the heating block, and measuring a transient response value R heater-T of thermal resistance of the heating block; and verifying whether a relationship between the transient response value R heater-T of thermal resistance of the one heating block and a steady-state response value R TTV-S of thermal resistance of the thermal test die is within a range of a setting variation with the software program of the processor, and when the relationship between the transient response value R heater-T of the thermal resistance of the one heating block and the steady-state response value R TTV-S of the thermal resistance of the thermal test die is not within the range of the setting variation, the target value is reset to determine another size of the one heating block that matches the reset target value, and wherein the reset target value is more close to the thermal resistance value R TTV of the thermal test die compared to the former set target value R Target .
