When version updating is tested：Test command is specially version updating test command.
Referring to Fig. 3, version updating test specifically includes following steps：
101, test terminal sends version updating test command to interchanger, which is used to indicate friendship
It changes planes and version updating test is carried out to CPLD.
In the present embodiment, the code that version updating file is write by the Verilog language run in test terminal, by patrolling
It collects converter software and is converted into version updating file, send and be stored in the memory chip of interchanger.It is tested in version updating
When, after interchanger receives the version updating test command that issues of test terminal, the CPLD that is sent out by the CPU of interchanger
The version updating file is recalled from memory chip and is written into CPLD by Update orders, so that CPLD carries out version more
Newly.If CPLD is updated successfully, interchanger update test information is first identifier；If CPLD update failures, interchanger update test
Information is second identifier.
102, whether test terminal receives the test information of interchanger transmission within the preset period, is, then enters step
Rapid 103；It is no, then enter step 104.
Wherein, which can be with sets itself, such as, but not limited to 3 minutes.
103, test terminal judges the test information received as first identifier or second identifier, if first identifier,
Then enter step 105；If second identifier, then 106 are entered step.
Wherein, second identifier includes version updating failure cause field.Wherein, the version updating failure cause field is available

Interchanger sends version updating test command, so that interchanger carries out version updating test to CPLD and returns to test information, surveys
Examination terminal determines version updating test result according to test information, and result is recorded to test log.It is tested in version updating
When number is not up to preset number, version updating test command is sent again from trend interchanger, in version updating test time
When number reaches preset number, test log is exported, to carry out test analysis, the CPLD test methods are in multiple test process
Without manual intervention, testing efficiency can be effectively improved.
In the register write test of CPLD, test command is specially register write test command.
Referring to Fig. 4, register write test includes the following steps：
201, test terminal writes test command to interchanger transmitter register, and enters step 202.
Wherein, which carries the register address to be tested of CPLD and the register to be written
First numerical value of the corresponding register in location, it is corresponding in the register address which is used to indicate interchanger
The first numerical value is written in register, if changing the interchanger after the first numerical value is written in the corresponding register of the register address
Function then returns to the test information for the changes of function notice for including corresponding first numerical value to test terminal.
202, test terminal judges whether the first numerical value of the write-in can change switch function；It is then to enter step
206；It is no, then enter step 203.
It should be noted that when carrying out register write test, interchanger itself is in operating status.
Rewriting for most of register, does not interfere with switch function, for such register only need into
Row write-read operation.But for certain specified registers, exchange opportunity generates corresponding action after it is written, for
Such register, register testing is just not suitable for judging using readwrite tests again, and can be judged by presentation.
203, test terminal transmitter register read command is to interchanger, and enters step 204.
The register read command carries the register address that the register write test command sent in step 201 carries, with
So that interchanger is read the second value of the corresponding register of the register address and is back to test terminal.
204, whether test terminal receives the test information including second value within the preset period；It is then to enter step
Rapid 205；It is no, then enter step 208.
205, test terminal judges whether second value is identical as the first numerical value, is, then enters step 207；It is no, then enter
Step 208.
What 206, test terminal received interchanger transmission within the preset period includes the function change of corresponding first numerical value
The test information for changing notice, is then to enter step 207；It is no, then enter step 208.
Specifically, if the function of interchanger changes, the test packet that terminal is returned according to interchanger is tested
The changes of function of the first numerical value of correspondence included notifies, judges whether interchanger presentation (such as interchanger weight as being expected occurs
Open, the port UP or DOWN of interchanger), it is on the contrary then enter step 208 if unanimously, entering step 207.
207, it determines that this test result is the corresponding register write success of register address, and this test result is remembered
Record is to test log, subsequently into step 209.
208, it determines that this test result is the corresponding register write failure of register address, and this test result is remembered
Record is to test log, subsequently into step 209.
Wherein, register write failure information includes：The write operation failure of which time and prompt when there is write operation failure
Information.
209, whether the number that test terminal judges to send test command is more than setting value, is then to enter step 210；It is no,
Then return to step 201.
210, terminate test, and export test log.
It can be intuitive to see by the test log of register testing, such as in the 1st time to the 200th time, which time goes out
Show write operation failure, and the information of the secondary write operation failure occurred, reason is searched will pass through the write operation failure information,
And it proposes a solution.
