Asynchronous communication is a common communication method between FPGA software and other chips. Due to various reasons, the rate of asynchronous communication may deviate from the theoretical value, and in some extreme cases, it may even cause data bit loss, frame loss, packet loss, etc. How to quickly and accurately detect the asynchronous communication rate deviation of FPGA software has become an urgent problem to be solved. In the related art, the communication rate is determined by detecting the start bit and the edge of the data bit of the serial interface of asynchronous communication. However, this method can only obtain the communication rate of the sending end of asynchronous communication, that is, only one communication rate can be obtained, which makes it impossible for relevant personnel to understand the boundary of the asynchronous communication rate of the FPGA software.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The field programmable gate array software asynchronous communication rate offset detection method provided in the present application is completed in a fully digital simulation environment. The tester builds a test platform in the fully digital simulation environment to effectively combine the functions of the device under test module, test data drive module, detector, data comparison module, scoreboard, etc., thereby completing the automated test of the asynchronous communication rate offset. Figure 1 A principle block diagram of field programmable gate array software asynchronous communication rate offset detection provided by one embodiment of the present application.

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] In a first aspect, an embodiment of the present application provides a method for detecting a software asynchronous communication rate offset of a field programmable gate array.

[0042] In one embodiment, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the method for detecting asynchronous communication rate deviation of field programmable gate array software of the present application. Figure 2 As shown, the field programmable gate array software asynchronous communication rate deviation detection method includes:

[0043] Step 210: determining a plurality of first rates based on a preset rate step length and a preset rate range, wherein the preset rate range is a preset asynchronous communication rate range of the field programmable gate array software to be tested, and the preset rate range is determined based on a theoretical rate of the field programmable gate array software communication and a preset offset parameter;

[0044] During specific implementation, the tester configures the theoretical rate, preset rate step length, preset rate range, preset offset parameter and data frame of the field programmable gate array software asynchronous communication interface to be tested. Exemplarily, when the theoretical rate of the field programmable gate array software asynchronous communication is set to 10000bps, the preset offset parameter is 5%, then the lower limit of the preset rate range determined based on the theoretical rate of the field programmable gate array software asynchronous communication and the preset offset parameter is 10000*(1-5%)=9500bps, and the upper limit of the preset rate range determined is 10000*(1+5%)=10500bps.

[0045] The preset rate range is a preset asynchronous communication rate range of the field programmable gate array software to be tested, and the first rate is an asynchronous communication rate determined from the preset rate range according to the preset rate step length.

[0046] A plurality of first rates are determined from a preset rate range according to a preset rate step length, so as to subsequently determine whether the offset detection result of each first rate passes.

[0047] Further, in one embodiment, the first rates are determined based on the preset rate step length and the preset rate range, and the corresponding formula is:

[0048] a i+1 =a i +d

[0049] a1=V min

[0050] Where i is a positive integer, a i is the i-th first rate, and the maximum value of i is when a i ≤V max And a i+1 >V max The value of i at the time, V min is the lower limit of the preset rate range, V max is the upper limit of the preset rate range, and d is the preset rate step length.

[0051] In specific implementation, several first rates are determined from a preset rate range according to the preset rate step length. For example, the preset rate range is [9500, 10500], d=10 is taken, and several first rates are determined as a1=9500, a2=9510, a3=9520...; preferably, d=1 is taken, and several first rates are determined as a1=9500, a2=9501, a3=9502...

[0052] In this embodiment, when the rate range is set to be relatively large, a plurality of first rates can be automatically determined by the above formula, which can improve the efficiency of determining the first rate.

[0053] Step 220: For each first rate, perform the following steps:

[0054] In a digital simulation environment, an excitation signal is input to a device under test module at a first rate. After the device under test module receives the excitation signal, the device under test module preprocesses the received excitation signal to obtain a preprocessed data frame, and determines whether the preprocessed data frame is consistent with a test frame. The excitation signal is generated by a test data driving module, and the content transmitted in the excitation signal is an encoded test frame. The device under test module is a field programmable gate array software to be tested.

[0055] If they are inconsistent, determining that the offset detection result of the first rate is failed;

[0056] If they are consistent, it is determined that the offset detection result of the first rate is passed, and the first rate, the theoretical rate, the rate offset difference of the first rate relative to the theoretical rate, and the rate offset ratio relative to the theoretical rate are recorded.

[0057] In specific implementation, after the tester completes the parameter configuration and runs the test, the software automatically determines several first rates, and for each first rate, performs the following steps:

[0058] The test data driving module generates an excitation signal, and inputs the excitation signal to the design under test module at a first rate, and simultaneously sends the data frame to the data comparison module;

[0059] After receiving the excitation signal, the DUT module performs preprocessing such as decoding on the received excitation signal to obtain a preprocessed data frame, and inputs the preprocessed data frame into the detector module. It should be noted that the preprocessing in this application includes but is not limited to decoding.

[0060] The detector module inputs the received pre-processed data frame into the data comparison module;

[0061] The data comparison module compares the preprocessed data frame with the test frame to determine whether the preprocessed data frame is consistent with the test frame. If the preprocessed data frame is inconsistent with the test frame, it means that there is data bit loss, frame loss, packet loss, etc., and the communication fails. At this time, the offset detection result of the first rate is determined to be failed, and the data related to the first rate is not recorded; if the preprocessed data frame is consistent with the test frame, it means that there is no data bit loss, frame loss, packet loss, etc., and the communication is successful. At this time, the offset detection result of the first rate is determined to be passed, and the detection result is transmitted to the scoreboard module;

[0062] The scoreboard module is responsible for recording the first rate, the theoretical rate, the rate offset difference of the first rate relative to the theoretical rate, and the rate offset ratio relative to the theoretical rate, and forming a text document.

[0063] Exemplarily, the preset rate range is [9500, 10500], d=1 is taken, and the excitation signal is first input to the design under test (DUT) module at the first rate a1=9500; after the DUT module receives the excitation signal, the excitation signal received by the DUT module is decoded and other preprocessed to obtain a preprocessed data frame; and further, it is determined whether the preprocessed data frame is consistent with the test frame. If the preprocessed data frame is inconsistent with the test frame, the offset detection result of the first rate 9500 is determined to be failed, and the data related to the first rate is not recorded; if the preprocessed data frame is consistent with the test frame, the offset detection result of 9500 is determined to be passed, and the first rate 9500, the theoretical rate 10000, the rate offset difference of the first rate relative to the theoretical rate and the rate offset ratio relative to the theoretical rate are recorded. At this time, the rate offset difference of the first rate relative to the theoretical rate, that is, the rate offset difference of 9500 relative to 10000, is 500, and the rate offset ratio of the first rate relative to the theoretical rate, that is, the rate offset ratio of 9500 relative to 10000 is -5%.

[0064] Then, the excitation signal is input to the DUT module according to the first rate a2=9501; after the DUT module receives the excitation signal, the excitation signal received by the DUT module is decoded and other preprocessed to obtain a preprocessed data frame; and it is determined whether the preprocessed data frame is consistent with the test frame. If the preprocessed data frame is inconsistent with the test frame, the offset detection result of the first rate 9501 is determined to be unpassed, and the data related to the first rate is not recorded; if the preprocessed data frame is consistent with the test frame, the offset detection result of 9501 is determined to be passed, and the first rate 9501, the theoretical rate 10000, the rate offset difference of the first rate relative to the theoretical rate, and the rate offset ratio relative to the theoretical rate are recorded. At this time, the rate offset difference of the first rate relative to the theoretical rate is 499, and the rate offset ratio of the first rate relative to the theoretical rate is -4.99%.

[0065] Then, repeat the above steps to determine the offset detection results of the first rates a3=9502, a4=9503, a5=9504, etc. respectively until a i The maximum value of i satisfies a i ≤V max And a i+1 >V max The test ends when

[0066] Assuming that 800 first rate offset detection results pass, there are 800 data in the recorded data, each of which records the first rate, theoretical rate, the offset difference of the first rate relative to the theoretical rate, and the offset ratio. All the recorded data are finally stored in a text file for testers and designers to analyze and understand the boundary conditions of the FPGA software asynchronous communication rate.

[0067] In this embodiment, a plurality of first rates are determined based on a preset rate step length and a preset rate range, wherein the preset rate range is a preset asynchronous communication rate range of the field programmable gate array software to be tested, and the preset rate range is determined based on a theoretical rate of the field programmable gate array software communication and a preset offset parameter; for each first rate, the following steps are performed: in a digital simulation environment, an excitation signal is input to a device under test module at the first rate, after the device under test module receives the excitation signal, the device under test module pre-processes the received excitation signal to obtain a pre-processed data frame, and determines whether the pre-processed data frame is consistent with the test frame, wherein the excitation signal is generated by a test data driving module, and the content transmitted in the excitation signal is the encoded test frame. Test frame, the module under test is the field programmable gate array software to be tested; if they are inconsistent, the offset detection result of the first rate is determined to be failed; if they are consistent, the offset detection result of the first rate is determined to be passed, and the first rate, theoretical rate, the rate offset difference of the first rate relative to the theoretical rate and the rate offset ratio relative to the theoretical rate are recorded. This method relies on a digital simulation environment and has a low test cost; no physical equipment is required and no damage is caused to the actual board equipment; this method can not only perform relevant tests before deploying the program on the actual chip, but can also be applied in the actual development process; the use of automated testing releases human resources and improves test results, so that relevant personnel can quickly understand the boundary conditions of the asynchronous communication rate of the FPGA software.

[0068] Furthermore, in one embodiment, the process of generating the excitation signal includes:

[0069] The test data driving module generates asynchronous communication interface data and uses the asynchronous communication interface data as an excitation signal.

[0070] It can be understood that the communication protocol of the field programmable gate array software to be tested needs to be predefined, wherein the data format of the asynchronous communication is clearly defined.

[0071] The test data driving module generates asynchronous communication interface data using a hardware description language (such as Verilog or VHDL) according to the asynchronous communication data format defined in the communication protocol of the field programmable gate array software to be tested, and uses the asynchronous communication interface data as an excitation signal.

[0072] In this embodiment, the test data driving module generates asynchronous communication interface data, and uses the asynchronous communication interface data as an excitation signal. Since the time calculation accuracy in the simulation test environment is at the picosecond level, the asynchronous communication rate offset detection result of the field programmable gate array software is more accurate.

[0073] Further, in one embodiment, the determining whether the preprocessed data frame is consistent with the test frame includes:

[0074] Step 310: determine whether the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame;

[0075] Step 320: If the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame, it is determined that the preprocessed data frame is consistent with the test frame, otherwise they are inconsistent.

[0076] The structure of a data frame generally includes a frame header, a data portion, and a frame trailer. The data bits in a data frame are the number of bits that make up the data portion of the data frame. The tester pre-configures the test data frame according to the communication protocol of the field programmable gate array software to be tested.

[0077] Exemplarily, the values ​​of the 6 data bits in the data frame pre-configured for testing are 1, 0, 0, 0, 0, 1, respectively. First, it is determined whether the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame; if the value of each data bit in the preprocessed data frame is 0, 0, 0, 0, 0, 1, that is, the value of each data bit in the preprocessed data frame is different from the value of the corresponding data bit in the test frame, then it is determined that the preprocessed data frame is inconsistent with the test frame; if the value of each data bit in the preprocessed data frame is 1, 0, 0, 0, 0, 1, that is, the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame, then it is determined that the preprocessed data frame is consistent with the test frame.

[0078] In this embodiment, it is determined whether the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame; if the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame, then the preprocessed data frame is determined to be consistent with the test frame, otherwise they are inconsistent, thus laying the foundation for determining the FPGA software asynchronous communication rate offset detection result.

[0079] In a second aspect, an embodiment of the present application also provides a field programmable gate array software asynchronous communication rate offset detection device.

[0080] In one embodiment, referring to Figure 3 , Figure 3 This is a functional module diagram of an embodiment of a field programmable gate array software asynchronous communication rate deviation detection device of the present application. Figure 3 As shown, the field programmable gate array software asynchronous communication rate deviation detection device 300 includes:

[0081] A determination module 301 is used to determine a plurality of first rates based on a preset rate step length and a preset rate range, wherein the preset rate range is a preset asynchronous communication rate range of the field programmable gate array software to be tested, and the preset rate range is determined based on a theoretical rate of the field programmable gate array software communication and a preset offset parameter;

[0082] The determination module 302 is configured to perform the following steps for each first rate:

[0083] In a digital simulation environment, an excitation signal is input to a device under test module at a first rate. After the device under test module receives the excitation signal, the device under test module preprocesses the received excitation signal to obtain a preprocessed data frame, and determines whether the preprocessed data frame is consistent with a test frame. The excitation signal is generated by a test data driving module, and the content transmitted in the excitation signal is an encoded test frame. The device under test module is a field programmable gate array software to be tested.

[0084] If they are inconsistent, determining that the offset detection result of the first rate is failed;

[0085] If they are consistent, it is determined that the offset detection result of the first rate is passed, and the first rate, the theoretical rate, the rate offset difference of the first rate relative to the theoretical rate, and the rate offset ratio relative to the theoretical rate are recorded.

[0086] Furthermore, in one embodiment, the determining module is specifically configured to determine a plurality of first rates according to the following formula:

[0087] a i+1 =a i +d

[0088] a1=V min

[0089] Where i is a positive integer, a i is the i-th first rate, and the maximum value of i is when a i ≤V max And a i+1 >V max The value of i at the time, V min is the lower limit of the preset rate range, V max is the upper limit of the preset rate range, and d is the preset rate step length.

[0090] Furthermore, in one embodiment, the judgment module is specifically used for:

[0091] Determine whether the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame;

[0092] If the value of each data bit in the preprocessed data frame is the same as the value of the corresponding data bit in the test frame, then it is determined that the preprocessed data frame is consistent with the test frame, otherwise they are inconsistent.

[0093] Furthermore, in one embodiment, the process of generating the excitation signal includes:

[0094] The test data driving module generates asynchronous communication interface data and uses the asynchronous communication interface data as an excitation signal.
