Peak current evaluation system and peak current evaluation method

A peak current evaluation system, comprising:

• a peak current evaluation apparatus, comprising:
• a pulse tuner, receiving a clock signal, adjusting pulse width and duty ratio of the clock signal according to at least one predetermined parameter in order to generate a pulse signal, wherein amplitude of the pulse signal is equivalent to a stress voltage;
• and
• a testing circuit, coupled to the pulse tuner, supplying the pulse signal to a testing device in order to measure resistance value of the testing device;
• and
• a peak current computing apparatus, measuring resistance value of the testing device, detecting whether the testing device has melted or not based on the measured resistance value, and calculating a peak current of the testing device when the testing device has melted.

A peak current evaluation method, comprising:

• receiving a clock signal;
• adjusting pulse width and duty ratio of the clock signal using a pulse tuner according to at least one predetermined parameter in order to generate a pulse signal with a stress voltage;
• applying the pulse signal to a testing device and measuring resistance value of the testing device;
• detecting whether the testing device has melted or not based on the measured resistance value;
• and
• determining a peak current of the testing device when the testing device has melted.
