Abstract

The invention discloses a method and apparatus for testing a chip. The apparatus includes: a field-programmable gate array which is intended for generating at least one testing image for testing a to-be-tested chip; a data conversion apparatus which is in electrical connection to the field-programmable gate array through a first data transmission interface of the field-programmable gate array, and is intended for converting the image data of the testing image generated by the field-programmable gate array to an object signal; the to-be-tested chip which is in electrical connection to the data conversion apparatus through a second data transmission interface of the data conversion apparatus, and is intended for, based on the object signal, generating a control signal, wherein the control signal is intended for controlling a display to display the testing image. According to the invention, the apparatus addresses the singularity of the functions of testing TCON of prior art.

Description

technical field [0001] The invention relates to the testing field, in particular to a chip testing method and device. Background technique [0002] When using traditional automatic test equipment (Automatic Test Equipment, referred to as ATE) for testing, the BIST (Built-in SelfTest) embedded in the timing controller (Timing Control, referred to as TCON) is generally used to verify the basic functions of the TCON. However, since the BIST embedded in TCON is only some very simple test images, such as solid colors. Therefore, the test for the internal logic of the TCON product is very limited, and this test method cannot cover the test of the DP input interface of the TCON. And once a new problem occurs in the mass production process, it is impossible to add a new test plan on the premise that the traditional test platform does not change the hardware platform, and if a new hardware platform is designed, it will take extra time and cost, and the impact will be great. unpredi...
