Abstract

The invention provides a digital circuit system test method. The method is characterized by carrying out test on collaborative modules in a digital circuit system in sequence through a power interface impedance test before powering up as well as a voltage correctness test, a phase-locked loop module clock test, a DDS accuracy and homologous stability test and an AD / DA access performance test after powering up, so that functions and performances of main modules in the digital circuit system can be subjected to comprehensive test, corresponding indexes of the digital circuit system can be evaluated effectively, test results can be obtained at a fastest speed, and reliability is high.

Description

technical field [0001] The invention relates to the testing field, in particular to a testing method for a digital circuit system. Background technique [0002] With the rapid development and application of electronic information technology and ultra-large-scale integrated circuits, the field and scope of digital signal processing technology applications are also expanding. Compared with analog signal processing, digital signal processing has the advantages of good flexibility, high precision and stability, convenient development and strong functions. A digital circuit system typically includes many modules that work together. After the digital circuit system completes the principle design, printed board production and welding assembly, it needs to be tested to ensure the correctness and reliability of the system. When the components of the digital circuit system board burn out or the circuit is damaged, it may be necessary to pass the test. repair. During the test proces...
