Abstract

The invention discloses a DAC interface verification method, device and system. The method comprises the steps of inputting a test signal to a DAC interface of a to-be-tested chip; and obtaining a test result of testing the to-be-tested chip. According to the invention, the technical problem of relatively low test efficiency in related technologies is solved.

Description

technical field [0001] The present application relates to the field of testing, in particular, to a verification method, device and system for a DAC interface. Background technique [0002] After the chip sample tapes out, the laboratory stage needs to verify the relevant functions of the chip, especially the digital-to-analog converter (DAC) function of the chip. A digital-to-analog converter (DAC) has a wide range of applications. As a communication bridge between the digital domain and the analog domain, the DAC has important applications in many important occasions. When DAC verification is performed in the traditional laboratory stage, the excitation is manually injected from each channel. In this way, when the number of channels is large, all channels need to be fully traversed in order to test the accuracy of the results. Taking 12 channels as an example, Full traversal needs to traverse from 12 0s to 12 1s in turn. This is a work with a huge workload but high repeti...
