Wireless communication device testability design method

Abstract

The invention discloses a wireless communication device testability design method. The method includes performing functional unit division on a wireless communication device, including a voice and panel unit, a processor unit, a baseband signal processing unit, a radio frequency unit, a power amplifier unit, a filter unit and a backboard unit, wherein the voice and panel unit, the baseband signal processing unit, the radio frequency unit, the power amplifier unit and the filter unit are connected with the processor unit through respective control interfaces and data communication interfaces via the backboard unit, and the voice and panel unit provides a device internal unit program upgrade interface and maintenance interface to the outside. Main faults of each unit are automatically diagnosed when the device is powered on, a test command is input through the maintenance interface when a fault occurs, a test signal passes through each unit inside and realizes loopback gradually, and the faults of each unit are diagnosed automatically. The wireless communication device testability design method has the beneficial effects of utilizing hardware resources of the device itself, increasing test software to realize testability design of the device itself, accurately positioning the faults inside the device, and greatly reducing debugging and testing and maintenance guarantee cost of the device.

Description

technical field [0001] The invention relates to a testability design method of wireless communication equipment, which belongs to the technical field of testability design of electronic products. Background technique [0002] In the field of digital wireless communication, communication equipment is becoming more and more complex, with higher integration, more powerful functions, and smaller structure size. The corresponding production test and maintenance test are more and more difficult, relying on traditional test methods It has been unable to solve this problem, therefore, it is proposed to increase the testability design requirement while designing the device function. [0003] At present, most products have not been planned for system testability design, and the testability of products is poor. The existing methods usually use boundary scan technology, but this method can only detect chip-level faults for devices with JTAG interface types. The interconnection fault de...
