FIG. 1 is a flow chart of a processing method for ATE testing according to an embodiment of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

s100, an SVF file is obtained, wherein the SVF file comprises a plurality of SVF statement segments, and each SVF statement segment comprises a plurality of SVF statements.
Those skilled in the art will appreciate that the format of the SVF file is known in the art and will not be described in detail herein. It should be appreciated that, there is a space between any two adjacent SVF sentence segments in the SVF file, and the SVF sentence segments in the SVF file may be determined by identifying the space.
S200, starting from a first SVF statement segment of an SVF file, judging whether the SVF statement segment included in the SVF file meets a preset first condition according to the sequence from top to bottom, and determining the first SVF statement segment meeting the preset first condition as a starting target segment; the first condition includes: the comment line of the SVF sentence segment is provided with a write command, the chain length of the SVF sentence segment is a preset chain length, and the element at the first preset position in the vector of the SVF sentence segment is a preset element.
Those skilled in the art will appreciate that the two initials for the annotation row in the SVF file are two exclamation marks. Alternatively, the present embodiment determines whether the comment line exists in the SVF statement segment by identifying whether two initials of the SVF statement are two exclamation marks. In this embodiment, whether a write command exists in the comment line is determined by searching whether a write character exists in the comment line, and if the write character exists in the comment line, the write command exists in the comment line is determined; otherwise, judging that the annotation line does not have a write command.
Those skilled in the art will appreciate that the instructions run by the SVF file are mostly SIR instructions, which are used to indicate commands to internal registers (IR registers) of the state machine, and SDR instructions, which are used to indicate commands to data registers (DR registers) of the state machine. As a specific embodiment, SDR 74 TDI (00000000787C 082C 67D) in the SVF file represents an SDR instruction, where 74 is chain length and 00000000787C082C67D is vector, as known to those skilled in the art.
In this embodiment, the preset chain length, the first preset position and the preset element may be all obtained by a mode of input in advance by the user, and as a specific implementation manner, the preset chain length input in advance by the user is 74, and the first preset position input in advance by the user includes the first 4 bits and the last 4 bits in the vector, where the preset element corresponding to the first 4 bits is 0000, and the last 4 is C67D. Thus, when a write command exists in the comment line of a certain SVF sentence segment in the SVF file, the chain length of the SVF sentence segment is 74, the first 4 bits in the vector of the SVF sentence segment are 0000, and the last 4 bits in the vector are C67D, the SVF sentence segment is determined as an SVF sentence segment satisfying the preset first condition.
In this embodiment, whether the SVF sentence segments included in the SVF file meet the preset first condition is determined according to the sequence from top to bottom, if a certain SVF sentence segment meets the first condition, the SVF sentence segment is determined as a starting target segment, and the SVF sentence segment behind the starting target segment is not determined.

In this embodiment, when the converted operation or SVF sentence segment is added to the operation list file, the position added to the operation list file refers to the position of the SVF sentence segment before conversion in the SVF file, that is, the relative positional relationship between the SVF sentence segment before conversion and the SVF sentence segment after conversion and other SVF sentence segments is kept unchanged.
In this embodiment, the preset address list is obtained by a manner of input by a user in advance, where the preset address list includes a plurality of addresses, and whether the addresses in the comment line of the SVF sentence segment exist in the preset address list is determined by matching the addresses in the comment line of the SVF sentence segment with each address in the preset address list. Specifically, in this embodiment, it is first determined whether an annotation line exists in the SVF sentence segment, if so, it is further identified whether an address key exists in the annotation line, and if so, the number after the address key is determined as the address. As a specific implementation manner, the annotation behavior of a certain SVF sentence segment in the SVF file is || dft_phy_write: addr 02003c data 0001, then addr is the address key, and 02003c is the address.
In this embodiment, the address existing in the preset address list is the address corresponding to the SVF file portion that the user desires to modify, if the address in the comment line of a certain SVF sentence segment does not exist in the preset address list, it is determined that the SVF sentence segment is not the SVF file portion that the user desires to modify, and the SVF sentence segment is directly added to the preset operation list file without converting and modifying the SVF sentence segment.
In this embodiment, the operations include two kinds, one is a write operation and one is a read operation, wherein the write operation includes a write key, a preset symbol, an address key, an address, a data key, and data, for example, the write operation is write:addr 02003C data 0001, wherein write is the write key, addr is the preset symbol, addr is the address key, 02003C is the address, data is the data key, and 0001 is the data. The read operation includes a read key, a preset symbol, an address key, an address, a data key, and data, e.g., the read operation is read, addr 02000f data 00ff, wherein read is the read key, addr is the preset symbol, addr is the address key, 02000f is the address, data is the data key, and 00ff is the data.
S400, outputting the operation list file.
