Embodiment one
Fig. 1, Fig. 3 and Fig. 4 are please referred to, the present embodiment provides a kind of test methods of the MIPI pins of communication module, can
The production test efficiency to the MIPI-DSI and multiple MIPI-CSI pins of communication module is improved, is solved due to manually judging band by accident
The quality risk come.
The MIPI-DSI is the HSSI High-Speed Serial Interface between processor and display module (such as liquid crystal display)；Institute
It is the HSSI High-Speed Serial Interface between processor and camera module to state MIPI-CSI pins.Communication module all can under normal circumstances
Include the MIPI-DSI interfaces of screen and the MIPI CSI interfaces of several groups of camera.
The test method of the present embodiment, including：
MIPI DSI interfaces and MIPI CSI interfaces is set to connect and compose communication loop.Optionally, in practice, Ke Yizhi
It connects and is connected to the signal that MIPI DSI interfaces export on MIPI CSI interfaces by equipment such as tool circuits.
Obtain the first data that MIPI DSI interfaces are sent out；Obtain the MIPI CSI interfaces institute being connect with MIPI DSI interfaces
The second data received；
MIPI CSI interfaces may have multiple, be illustrated for three herein, specially MIPI CSI0, MIPI
CSI1 and MIPI CSI2.It is connect successively with MIPI DSI interfaces by each in the multiple MIPI CSI interfaces of control
To complete the test to each MIPI CSI interface.
In the present embodiment, the switching that is controlled by software switch realize each MIPICSI interfaces of switching successively with MIPI
DSI interfaces connect.
Wherein, MIP signal transfer modes include high-speed mode and low-speed mode, and the present embodiment is by software by MIPI DSI
The transmission of data is carried out according to high-speed mode, when test can not only cover all data channel as far as possible, it is ensured that test is complete
Face, while also more meeting practice scene.
In test process, after software control switching switching to MIPI CSI0 interfaces, MIPI DSI transmission datas are led to
It crosses and obtains the first data that MIPI DSI are sent.MIPI CSI0 receive the data that MIPI DSI are sent, by obtaining MIPI
The second data that CSI0 is received.As with the physical layer protocol of MIPI CSI interfaces being due to MIPI DSI interfaces,
By directly judging whether the first data consistent with the second data, can confirm communication module whether failure.If two data
It is consistent, then judges that the pin work of MIPI DSI interfaces and MIPI CSI0 interfaces is all normal；If two data differ
It causes, can not either get the first data or the second data, then judge that there are failures for the communication module.Because if MIPI
DSI pins are problematic, such as the signal pin of pin shorted to earth or communication module inside chip open circuit, then MIPI DSI
Pin normally transmission data, MIPI CSI1 pins cannot not receive data, or the data and transmission received data not
Unanimously.
After MIPI CSI0 interface testings, controlled in switching switching to MIPI CSI1 interfaces by software, together
The first data that sample is sent by obtaining MIPI DSI.MIPI CSI1 receive the data that MIPI DSI are sent, by obtaining MIPI
The second data that CSI1 is received.If MIPI CSI0 interfaces are consistent with the data of MIPI DSI before, it can be determined that
Be all normal.It therefore, can be directly by judging the first data when being directly switch to the judgement of connection MIPI CSI1
It is whether consistent with the second data, determine whether MIPI CSI1 are problematic, to screen malfunctioning module.
And so on, the test to MIPI CSI interfaces such as subsequent MIPI CSI1 and MIPI CSI2 all need to only lead to
It crosses in software control switching switching to corresponding MIPI CSI interfaces, obtains the first data that MIPI DSI are sent, and
Corresponding MIPI CSI interfaces receive the data that MIPI DSI are sent, then carry out comparison judge whether it is unanimously corresponding to determine
Whether MIPI CSI pins are problematic, and malfunctioning module is screened.
In one specifically uses scene, referring particularly to Fig. 3 and Fig. 4, MIPI-DSI transmits one group of data (i.e. the first data),
If MIPI-DSI interfaces are normal, the format of data is as shown in Figure 3；
Also assume that MIPI CSI interfaces are also normal, format such as Fig. 4 institutes of received data (the second data)
Show.Wherein, Lane:Channel, Byte:Byte, SerDes:English SERializer (serializer)/DESerializer (unstrings
Device) abbreviation.
During actual test, it can judge by the way that whether compare the format of the first data and the second data completely the same
Communication module whether failure.
Embodiment two
The present embodiment provides a kind of storage mediums, are stored thereon with computer program, and described program is called by processor
When, can by execute embodiment one in specifically test all steps for being included realize automatically, high efficiency, high-accuracy
Test communication module MIPI interfaces whether failure.
Embodiment three
The present embodiment corresponding embodiment one and embodiment two provide a kind of MIPI pins test system of communication module, packet
Include tested communication module 1 and a test fixture 2；
The tested communication module 1 includes MIPI DSI interfaces and MIPI CSI interfaces；Optionally, the MIPI DSI
Interface have it is multiple, such as MIPI CSI0, MIPI CSI1 and MIPI CSI2.
The test fixture includes at least at least one processor 22, the storage medium 21 of embodiment two and signal
Switch switch 23；The signal shift switch controls for software.May participate in Fig. 5, be one specifically with test fixture in scene with
The connection of tested communication module and signal interaction schematic diagram.
In test process, MIPI DSI interfaces and MIPI CSI interfaces are one-to-one connects and composes circuit.
In conclusion the test method and its system of a kind of MIPI pins of communication module provided by the invention, storage are situated between
Matter can not only realize automatic test interface, significantly improve testing efficiency, ensure module quality；But also support is right simultaneously
