Utilize the programming tool of different manufacturers on the JTAG chain generate respectively several different-formats chaining programming file concrete generative process can referring in second kind of online programming mode a) and b) description of part.
Below the chaining programming file of the different-format that generates is resolved, the programming content of obtaining the respective logic device describes, and referring to Fig. 5, the programming content of chaining programming document analysis being obtained the respective logic device comprises:
Step 21:, carry out cyclic redundancy (CRC) verification of corresponding form according to the form of chaining programming file; As: the chaining programming file layout of input is .jbc, then carries out jbc form corresponding check, jbc_crc_check;
Step 22: judge whether cyclic redundancy check (CRC) is correct, when cyclic redundancy check (CRC) is correct, execution in step 23; Otherwise finish;
Step 23:, resolve the programming content of positional information, jtag instruction register length information and the respective logic device of each logical device on the JTAG chain according to the form of chaining programming file.
After generating described chaining programming file, the resolving of different-format is set according to the form (forms such as .jbc .vme) of each chaining programming file, parse logical device information, instruction length and programming content etc. on the concrete JTAG chain, finish loading and programming logical device on the JTAG chain.
Concrete: after obtaining chaining programming file,, carry out the parsing of corresponding form as .jbc form, vme form according to the form of chaining programming file.The chaining programming file of every kind of form can store fixing information in the fixed position, and table 1 is depicted as the chaining programming file layout of .jbc form:
The chaining programming file format table of table 1 .jbc form
Last table has just carried out some simple analysis to the form of .jbc file, and the left side one row target is the address.First_word (4A414D01) fixes, and also might be 4A414D00, in the first address of chaining programming file if these two values then can parse the chaining programming file into the .jbc form, and be to be generated by the QUARTUS programming tool.Ensuing action_table, procdure_table, storages such as string_table be the address of variable, these variablees all are meant the aciculiform formula, retrieve the corresponding value of information according to the address of pointer indication from the relevant position of chaining programming file.Therefore the chaining of .jbc form programming file is to form according to a kind of arrangement architecture of this pointer basically, in all useful informations are included in entirely.After correspondence position reads corresponding information, can obtain the positional information of each logical device on the form, version information, compilation tool, JTAG chain of file, the data programmed content of respective logic device etc. according to the chaining of this form programming file.
In the present embodiment step 22, if chaining programming file layout is the .jbc form, cyclic redundancy data Crc_section in jbc_crc_check check results of carrying out and the chaining programming file compares, deposit the position cyclic redundancy data Crc_section as 0x28-0x2b in the table 1, for follow-up parsing and online programming provide the accuracy assurance.Other as.Though the implication of data is different in the deposit position of the chaining of forms such as vme programming file and the chaining programming file data of .jbc form and each position, just deposits the form difference, resolving is similar, exemplifies no longer one by one at this.
Behind programming Context resolution to different-format chaining programming file, obtain the programming content of positional information, jtag instruction length and each logical device of each logical device, then each logical device is carried out online programming, back extended meeting is specifically described the programme process of load content of logical device.
The 4th kind of online programming mode generates a chaining programming file that comprises the serial vector format of all logical device information on the JTAG chain, utilizes described chaining programming file that arbitrary logical device on the JTAG chain is carried out online programming.
Below in conjunction with Fig. 2 and Fig. 6 the method for the 4th kind of online programming of logical device is described.
Fig. 6 is method embodiment three process flow diagrams of logic device on-line programming of the present invention.As shown in Figure 6, present embodiment comprises:
Step 1: the chaining programming file that generates a serial vector format that comprises each logical device positional information on the JTAG chain, jtag instruction register length, each logical device programming content;
Step 2: described chaining programming file is resolved, obtain the programming content of each logical device, each logical device on the JTAG chain is carried out online programming.
Step 11: generate the programming file comprise the single serial vector format of single logical device programming content and jtag instruction register length on the JTAG chain;
Step 12:, generate or each single programming file edit is generated the chaining programming file of a serial vector format with arbitrary programming tool according to the position of each logical device on the programming file of above-mentioned single serial vector format and the JTAG chain.
Below in conjunction with Fig. 2 the generative process of serial vector format chaining programming file is illustrated: for example, 1,3 is the device of ALTERA company among Fig. 2, and 2,4 is the device of LATTICE company; Generating a chaining programming file that comprises the serial vector format of logical device 1-4 comprises:
A) generate the single programming file that comprises individual devices programming content and jtag instruction register length respectively.Utilize the programming tool of ALTERA company to generate single programming file 1.pof, the 3.pof of corresponding form respectively as logical device 1 and 3; Logical device 2 and 4 utilizes the programming tool of LATTICE company to generate single programming file 2.jed, the 4.jed of corresponding form respectively;
B) the single programming file of each logical device different-format on the JTAG chain to be generated a chaining programming file, need earlier the single programming file of different-format to be generated the programming file of serial vector format, as: utilize the programming tool of LATTICE company 2.jed and 4.jed to be converted to programming file 2.svf, the 4.svf of serial vector format (Serial Vector Format is abbreviated as svf).The serial vector format is the file layout that different programming tools can generate, and all logical devices are all supported the programming file of this form;
C) use arbitrary programming tool, as: the programming tool ispVM of LATTICE company, the single programming file of 4 serial vector formats is generated a chaining programming file that comprises device 1-4 serial vector format, perhaps each single programming file edit is generated a chaining programming file that comprises device 1-4 serial vector format:
Utilize the chain editting function of programming tool, position priority according to logical device, the single programming file of 4 single serial vector formats is generated the chaining programming file of a serial vector format, perhaps, each single serial vector format programming file edit is merged the chaining programming file that generates a serial vector format according to the location order of each logical device on the JTAG chain.
Therefore, utilize arbitrary programming tool or edit can generate the chaining programming file of a serial vector format, comprise the position of each logical device on the JTAG chain in this chaining programming file, programming content and jtag instruction register length.After generating the chaining programming file of a serial vector format, described chaining programming file is resolved, obtain the programming content of each logical device, then arbitrary logical device on the JTAG chain is carried out online programming.
The serial vector format has defined a cover grammer, in order to the scanning sequency and the process of description jtag instruction and data, and the content of instruction and data, be the descriptive language of JTAG channel link action.It is different with the chaining programming file of .jbc or .vme form that (the chaining programming file as the .jbc form that table one exemplified is the binary code that is difficult to distinguish, be difficult for recognition), it is equally readable than higher that the files classes of serial vector format are similar to the C language file, the content of the chaining programming file of this form is readable, even can edit as required, therefrom can directly parse programming instruction, data content and the positional information etc. of each logical device, obtain again each logical device to be loaded corresponding programming content after each logical device information.
First kind and second kind of online programming mode need generate several single programming files or chaining programming file; And call corresponding transplanting code respectively, and each logical device on the JTAG chain is carried out online programming, these two kinds of programming modes and programming process are fairly simple, but are subjected to the restriction that code is transplanted by each producer; The third online programming mode also needs to generate the chaining programming file of several different-formats, transplants code but never call producer during later programmed, and the chaining programming file of the different-format that generates is resolved, and has removed producer to transplanting the privately owned protection of code; The 4th kind of online programming mode realized the online programming to logical device on the JTAG chain equally, generate the chaining programming file of a serial vector format, and, can finish loading and programming to all logical devices with the chaining file of programming to the chaining of described serial vector format programming document analysis.
