Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
Embodiment one
Fig. 1 is a kind of circuit theory diagrams for chip circuit that the embodiment of the present invention one provides, and the present embodiment is applicable to respectively
The module of kind electronic equipment, such as display screen, Trackpad etc., as shown in figure 1, the chip circuit, including：Main control chip 101, letter
Number detecting element 103 and switching switch 102；
The test side of signal detection component 103 is connected with least one signal output part of main control chip 101, to detect phase
The output signal of signal output part even；The detection output of signal detection component 103 and a signal of main control chip 101 are defeated
Enter end to be connected；
The not moved end of switching switch 102 is connected with the standby output end of main control chip 101；The each of switching switch 102 moves
End is connected with a signal output part respectively；The controlled end of switching switch 102 is connected with the control terminal of main control chip 101；
When detecting the output failure of signal output part, the control switching of main control chip 101 switch 102 connects the signal output
Moved end corresponding to end and not moved end, and output signal corresponding to the signal output part is exported by standby output end.
In this programme, by signal detection component 103 detect main control chip 101 at least one signal output part it is defeated
Go out signal, in specific implementation process, according to the statistics to product bug one or more fault rates can be selected higher
Signal output part is as detection object；If the disposal ability of main control chip 101 and the wiring space of circuit are enough, Ke Yixuan
Select and signal detection is carried out to all signal output parts, to monitor the signal output state of main control chip 101.
For main control chip 101, except realizing the normal output needed for module function, it is also necessary to set a signal
Input accesses testing result；Standby output end is set to take over output in some signal output part output abnormality；Control is set
End controls the conducting state of standby output end output point corresponding with the signal output part of exception.
In Fig. 1, the standby output end of main control chip 101 is BACKUP, signal input part INPUT, and control terminal is
OUTPUT, wherein receiving the signal output part of detection includes RST and EINT.As shown in figure 1, signal detection component 103 is to each
The output result of signal output part is detected, and testing result is fed back to the signal input part progress shape of main control chip 101
The judgement of state, if the exception of some signal output part, the conducting of switching switch 102 is controlled by control terminal output control signal
Output point corresponding to standby output end and abnormal signal output part, maintains the signal output described in module normal operation.
In specific implementation process, switching switch 102 can be selected as single pole multiple throw, the not moved end of single pole multiple throw
It is connected with the standby output end of main control chip 101, each moved end of single pole multiple throw is connected with a signal output part respectively,
When not detecting abnormal, single pole multiple throw maintains a normally open state, when the signal output for having a signal output part is abnormal
When, the moved end that output point corresponding to the signal output part connects can be connected from different ends, be substituted and carried out by standby output end
The output of the abnormal signal output part.Such as signal output part RST output signals under normal circumstances, work as signal detection component
103 when can not detect signal output part RST output, and main control chip 101 assert that signal output part RST is abnormal, now passes through
Signal output part RST is corresponded to output point and standby output end by control terminal OUTPUT output controls instruction control switching switch 102
BACKUP is turned on, and carries out signal output by standby output end BACKUP substitution signal output ends RST, i.e. main control chip 101 controls
Originally changed by the signal output part RST signals exported and exported by standby output end BACKUP.Alternatively, it is also possible to select single-pole single-throw(SPST
Switch, concrete operating principle is similar with single pole multiple throw, now adjusts a single-pole single-throw switch (SPST) every time.If only one
Standby output end, the exception of a signal output part can be received without influenceing normal use；If multiple standby output ends,
It is corresponding to receive multiple signal output parts exceptions without influenceing normal use.
For some main control chips 101, the output signal of signal output part is high level signal or low level signal；
Corresponding, the output signal of standby output end is low level signal or high level signal；
Corresponding switching switch 102 is also in series with NOT gate.
Some main control chips 101 fix some or some standby pin outputs in design, if desired now
The opposite signal of level, NOT gate of directly connecting carry out the conversion of low and high level.
To be easy to control, switching switch 102 be relay switch, such as optical relay switchs.
Or switching switch 102 is triode, existing triode can have been realized miniature by microelectric technique
Change, such as thin film transistor (TFT).
In summary, the present embodiment is by detecting the output state of the signal output part of main control chip, in signal output part
Output failure when, the signal output part that failure is taken over by standby output end continues corresponding signal output, maintains
The normal output of all signals of main control chip, avoid causes module integrally unavailable because of the failure of some pin pin, carries
The high fault-tolerant ability of module, extend the service life of module.
