The serial number generator interfaces with serial number generators 1-N, each serial number generator (serial number generator 1 103, serial number generator 2 and serial number generator N105 shown in fig. 1) needs to provide consistent serial number data output information for the serial number generator according to the agreed interface definition, one serial number generator realizes one serial number generation rule, and if a new serial number generation rule exists, one serial number generator is realized again. 109 denotes a sequence number generator and a call specification intermediate the sequence number generator.

In one embodiment, after receiving the information that the writing of the data fed back by the chip is successful, the chip driving module reads the current data on the chip, compares the current data with the recording data stream, and if the current data is consistent with the recording data stream, sends serial number completion information to the serial number generator; and/or the serial number generator releases the appointed serial number generator after receiving serial number completion information of all chips to be burned in the current batch.
In this embodiment, after all the chips to be burned in the current batch are burned, the serial number generator can clean the corresponding designated serial number generator (DeInit), and finally clean the generator, release the resources, and call the Init in a peer-to-peer manner.
Specifically, referring to the timing chart shown in fig. 3, the working process of the chip serial number burning device includes:
1. the method comprises the steps that a chip driving module receives a burning request sent by a chip in burning setting;
2. the sequence number generator assigns and initializes a sequence number generator (fig. 3 specifically an assigned sequence number generator N);
3. the chip driving module in the burning setting sends serial number request information to the serial number generator to request to generate a serial number;
4. the serial number generator receives serial number request information and sends serial number record group generation information to the serial number generator N;
6. the serial number generator N receives serial number record group generation information, generates a serial number record group and returns the serial number record group to the serial number generator;
5. the serial number generator reads the current serial number from the serial number record group and sends the current serial number to the data processing module;
7. the data processing module puts the current serial number into a burnt data stream;
8. the chip driving module writes the burnt data stream into the chip;
9. the chip informs whether the data writing is successful;
10. the chip driving module reads data in the chip;
12. the chip driving module compares the read data with an original data stream (a burnt data stream);
13. the chip driving module reports a result according to the comparison result; after judging that the serial number is successfully written into the chip, sending serial number completion information to a serial number generator;
14. after all the chips to be burned in the current batch are burned, the serial number generator releases the designated serial number generator (i.e. the serial number generator N shown in fig. 3).
Specifically, the sequence number record group includes an array of a plurality of sets of record sequence numbers.
In this embodiment, when the serial number generator requests the serial number generator to generate a serial number record group, one serial number record includes a chip address where the client wants the serial number to be written, the number of bytes occupied by the serial number, and the content, and the serial number record group is an array including a plurality of serial number records. Thus, the requirement that a chip can have data of a plurality of places as serial numbers possibly desired by a customer can be met.
Before requesting a sequence number group, the sequence number generator needs to be initialized by calling the allocation and initialization method provided by the generator after the corresponding user (such as an external client) selects the designated generator, and a designated configuration file is allowed to be imported to the sequence number generator for informing the initialization parameters during initialization. And finally, when the serial number is not used any more, the corresponding interface is required to be called for releasing the serial number generator. To prevent errors in writing data, after the chip data is written successfully, the data needs to be read back from the chip and compared with the original data stream to determine that the data is written correctly into the chip.
In one embodiment, the chip driving module obtains a first data range of initial burning data and sends the first data range to the data processing module; the data processing module acquires a second data range of the current serial number, identifies an intersection part between the first data range and the second data range, and merges serial number data of the intersection part into the initial burning data to obtain a burning data stream.
The embodiment can realize the combination of the current serial number and the corresponding initial data stream, and obtain the accurate and complete burnt data stream. Specifically, the process of merging the serial number data carried by the current serial number into the corresponding burnt data stream may be as follows:
1. the chip driving module acquires the start position (StartAddress) and the Length (Length) of the recording data (initial recording data) to determine a first data range;
2. the data processing module obtains whether serial number data exists in a first data range [ StartAddress, startAddress +Length-1] of the request when the chip driving module requests, wherein "[ ]" represents a closed interval, for example, the Length from StartAddress being 0 is 10 bytes, and the Length is represented as [0,9]. Assuming that the range of the sequence number data is [ SNStartAddress, SNStartAddress +SNLength-1], wherein SNStartAddress is the starting position of the sequence number data, SNLength is the length, if two intervals have an intersection, merging the sequence number data of the intersection part into returned request data, and the non-intersection part data in the request data range is derived from the original archive data.
In one example, assume that the now drive requests to read data of [0,9], which is originally 0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0a, and the valid range of sequence number data is four bytes from address 0, which is 0x12,0x34,0x56,0x78. Then after merging, the drive will get 10 bytes of data, 0x12,0x34,0x56,0x78,0x05,0x06,0x07,0x08,0x09,0x0a, where the 0x beginning indicates that the value is 16-ary data. If the valid range of sequence numbers is four bytes from address 8, the values are 0x12,0x34,0x56,0x78, then 0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x12,0x34 will be obtained by the merge driving. The following describes various cases of the merging case:
case 1: (snstartaddress+snlength-1) < StartAddress, no intersection, no merging, as shown in fig. 4 (a).
Case 2 (StartAddress+Length-1) < SNStartAddress, no intersection, no merging, as shown in FIG. 4 (b).
Case 3: SNStartAddress < StartAddress ]
And (snstartaddress+snlength-1) > = (startaddress+length-1). The sequence number data is merged at [ StartAddress, startAddress +Length-1], as shown in FIG. 4 (c), where the hatched data is merged.
Case 4: SNStartAddress < StartAddress ]
And (SNStartAddress+SNLength-1) < (StartAddress+Length-1).
The sequence number located [ StartAddress, SNStartAddress +SNLength-1] data is merged as shown in FIG. 4 (d), where the shaded data is merged.
Case 5: SNStartAddress > StartAddress
And (SNStartAddress+SNLength-1) > StartAddress+Length-1. The sequence number located [ SNStartAddress, startAddress +Length-1] data is merged as shown in FIG. 4 (e), where the shaded data is merged.
In one embodiment, the serial number generator allocates and initializes the serial number generator after the chip driver module receives the burn request, so that the designated serial number generator is initialized.
As one embodiment, the specified sequence number generator initializes the present generator to receive a configuration file; displaying a setting interface, and reading sequence parameters set by a user in the form of an interactive interface; reading setting completion information input by a user through the interactive interface, recovering initialization, closing the interactive interface, and generating a serial number group according to the configuration file and the sequence parameters.
In one example, in the chip serial number burning process, the interface call flow of each serial number generator including the designated serial number generator may be shown with reference to fig. 5, where the interface method provided by the serial number generator includes:
1. an initialization generator (Init) allows to transfer a configuration file containing the creation information.
2. A setup interface (ShowDialog) is presented that allows the builder to interface with the operator for parameter settings.
3. A setting (DoOK) is determined, and the method is invoked after the operator setting is completed.
4. Restoration initialization (DoReset), the operator performs restoration setting initialization.
5. Closing the setup interface (closedialogs), closing the interactive interface.
6. And (3) requesting a serial number (QuerySN), wherein the request generator generates a serial number group, and transmits the current chip burning number, the UID of the chip and the custom CID. The burn number starts from 1 and is incremented by 1 each time. The UID of the chip is the identity card of each chip, the chips manufactured by the chip manufacturer are solidified in the chips leaving the factory, and the chips of the same model and batch are different. CID is a customer-defined ID (Custom ID), such as a two-dimensional code on a PCBA board, so that in order to track board information, different two-dimensional codes exist on different boards, the two-dimensional codes participate in serial number generation calculation, and the chip and the PCBA board are bound.
7. The producer (DeInit) is cleaned up, and at the end, the producer is cleaned up, the resources are released, and the resource is called with the Init in a peer-to-peer mode.
In this example, the implementation of the corresponding interface adopts a dynamic library manner, so that the dynamic loading of the burning software can be facilitated, the work of the serial number generator is independent of the burning software, and the serial number generator can work normally when any chip and a plurality of chips are burned simultaneously. The serial number generator has a lock function, and can ensure the data integrity during concurrent access. The specific serial number data recording position and length are configured through an interface, and are determined by a client according to the actual condition of self-recording, if a plurality of chips are recorded simultaneously, the serial number data recording position and length expected by the simultaneously recorded chips are ensured to be the same.
As an embodiment, after the specified sequence number generator obtains the burning information setting instruction, sequentially calling an SNCreateWindow interface, an SNShowWindow interface, an SNInitCtrlsValue interface, an SNGetCtrlsValue interface, and an sndestrewingw interface, and calling an SNPreLoad interface; the SNCreateWindow interface is used for requesting the sequence number generator to create a window for information setting of a client, wherein the information setting comprises a sequence number burning address, a length, a group number, an initialization file selection and the like; the SNShowWindow interface is used for requesting the sequence number generator to display the window which is already created; the SNInitCtrlsValue interface is used for requesting the sequence number generator to set the initial value of the control on the window; the SNGetCtrlsValue interface is used for requesting the serial number generator to return to the final setting of the client; the SNDestroyWindow interface is used for requesting the sequence number generator to destroy the created window; the SNPreLoad interface is used for requesting the pre-loading of the serial number generator, and the pre-loading allows the generator to perform initialization preparation of a serial number generation environment according to the setting, including resource allocation, initialization of corresponding variables and the like;
the appointed sequence number generator also calls the SNQuery interface and the SNTellResult interface in sequence, and returns to execute the process of calling the SNQuery interface when the sequence number is required to be acquired in the current burning period until the sequence number is not required to be acquired in the current burning period; the SNQuery interface is used for requesting the serial number generator to return serial number data, wherein the serial number data comprises a plurality of serial number records, and one serial number record comprises a chip address input by a user, the number of bytes occupied by the serial number and content; the SNTellResult interface is used for informing the burning result of the serial number generator.
Specifically, the sequence number generator calls an SNUnLoad interface after the sequence number is not required to be acquired in the current burning period; the SNUnLoad interface informs the generator of recycling resources and does not call other interfaces.
The interface method call flow provided in this embodiment may refer to fig. 6, where the interface convention provided by the sequence number generator to the sequence number generator includes initialization (SNPreLoad) and release (snuload), allowing the same generator to generate different outputs under the action of different configuration files (the interface displayed by SNShowWindow allows the client to set), and may allow a call to obtain multiple sets of sequence numbers to be burned into the same chip.

when the burning device performs chip burning action (such as triggering a burning execution command when a burning function button on a corresponding control end or a burning function button on a programmer is pressed), sending serial number request information to the serial number determining device;
the serial number generator receives the serial number request information and sends serial number record group generation information to a designated serial number generator; the appointed serial number generator is a serial number generator selected by a user;
