Abstract

The invention relates to the technology of electronic product testing. The invention solves a problem that the existing voltage margin reliability testing scheme is low in testing efficiency and high in cost and provides a testing device and a testing method for the reliability of a voltage margin. The technical scheme is summarized as follows: in the testing device for the reliability of the voltage margin, a first testing end is connected with a second testing end through a first I2C adjustable resistor, the second testing end is connected with a third testing end through a second I2C adjustable resistor, the third testing end is connected with a device ground wire, a clock module and a user interaction module are connected with a microcontroller respectively, the microcontroller is connected with an I2C interface of the first I2C adjustable resistor and an I2C interface of the second I2C adjustable resistor through an I2C bus, and a power supply module supplies power to each module. The beneficial effects are that the testing is convenient, and the invention is suitable for testing the voltage margin.

Description

technical field [0001] The invention relates to electronic product testing technology, in particular to the voltage margin reliability testing technology of electronic products. Background technique [0002] With the rapid development of electronic technology, the scale of electronic products is becoming more and more complex. Many electronic products require continuous reduction of single-board power consumption to solve the problem of product miniaturization. This reason directly leads to chip manufacturers designing multiple voltages to reduce single-board power consumption. power consumption. Due to the existence of various voltages in large-scale electronic products, and the voltage signal is the core part of electronic products, if there is no certain margin, it will directly affect the stability of the equipment under different working conditions such as environment and temperature. Therefore, in the research and development stage of electronic products, it is necess...
