Embodiment Construction
[0072] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0073] Such as figure 1 As shown, the present invention provides an automatic detection device for chip power-on reliability, including a PC for running test software and a test board for chip testing. The PC is connected with the test board through a serial port cable and communicates.
[0074] The test software is installed in the PC, and the test software receives the chip type, test intensity (that is, the number of repeated power-on times), power-on sequence (core power supply first, then I / O power supply, or vice versa) and power-on voltage value input by the tester. And the control information of the time interval (that is, the time difference between power-on of the core and I / O, in order to avoid damage to the chip caused by too long interval, the time difference is limited to 1s by software judgment), and the test software ...
