Description

Technical Field

[0001] The present application relates to the technical field of waveform downloading, and in particular to an AWG (Arbitrary Function Generator) waveform editing and downloading optimization method and device. Background Art

[0002] AWG is the best instrument for simulation experiments. Arbitrary waveform generator is a type of signal source, which has all the characteristics of signal source. Signal source mainly provides the required known signal (various waveforms) to the circuit under test, and then uses other instruments to measure the parameters of interest. It can be seen that the signal source does not measure any parameters in electronic experiments and test processing, but simulates various test signals according to the user's requirements and provides them to the circuit under test to meet the test needs.

[0003] However, current waveform files often take up a large storage space. In the process of downloading waveform files to hardware, data errors are prone to occur or the waveform files are lost due to exceeding the receiving range of the hardware, which needs to be solved.

[0004] Application Contents

[0005] The present application aims to solve one of the technical problems in the related art at least to some extent.

[0006] To this end, the first purpose of this application is to propose an AWG waveform editing and downloading optimization method, which can occupy a smaller memory when storing waveforms, and there will be negative feedback before the data is sent down, effectively avoiding data errors or exceeding the receiving range of external equipment, resulting in the loss of waveform files.

[0007] The second objective of the present application is to provide an AWG waveform editing and downloading optimization device.

[0008] The third objective of the present application is to provide an electronic device.

[0009] A fourth object of the present application is to provide a non-transitory computer-readable storage medium.

[0010] To achieve the above-mentioned purpose, the first aspect of the embodiment of the present application provides an AWG waveform editing and downloading optimization method, comprising the following steps: editing a WAVE set based on a preset function library, and defining the playback order of the sequence through a preset external command SEQ, so as to assign the sequence defined by the ADVS statement and the SEQ statement to the corresponding channel for waveform editing; parsing the WAVE set, and according to the ADVS and the SEQ statements, parsing the composition of the subsequence set and each sequence waveform to obtain a data file and a description file; extracting the number of data interface channels and storage capacity of the hardware, and when the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the storage capacity of the hardware, according to the OUT assignment, downloading the corresponding waveform set and sequence playback mode to the hardware for execution.

[0011] According to the AWG waveform editing and download optimization method of the embodiment of the present application, the data file and the description file are obtained after the waveform data is edited and processed. The download can only be performed when the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the hardware storage capacity. Therefore, a smaller memory can be occupied when storing the waveform, and there will be negative feedback before the data is sent, which effectively avoids data errors or exceeds the receiving range of the external device, resulting in the loss of the waveform file.

[0012] In addition, the AWG waveform editing and downloading optimization method according to the above embodiment of the present application may also have the following additional technical features:

[0013] In one embodiment of the present application, the parsing of the WAVE set includes: when using a function to generate a waveform, if the length of the waveform does not meet a preset condition, then during parsing, zeros are automatically added to make its length meet the preset condition, so that the lengths of the waveforms involved in the operation are consistent.

[0014] In one embodiment of the present application, it also includes: after parsing all basic waveforms edited by the user, sending them to hardware for storage in a first preset format, wherein a storage table is established according to the start address and end address of each waveform.

[0015] In one embodiment of the present application, the parsing of the subsequence set and the composition of each sequence waveform further includes: when using ADVS and SEQ types, parsing the number of sequences, the composition structure of the sequences and the sequence playback mode.

When the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the storage capacity of the hardware, according to the OUT assignment, the corresponding waveform set and sequence playback mode are downloaded to the hardware for execution.

[0018] According to the AWG waveform editing and download optimization device of the embodiment of the present application, the data file and the description file are obtained after the waveform data is edited and processed. The download can only be performed when the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the hardware storage capacity. Therefore, a smaller memory can be occupied when storing the waveform, and there will be negative feedback before the data is sent, which effectively avoids data errors or exceeds the hardware receiving range, resulting in the loss of the waveform file.

[0019] In addition, the AWG waveform editing and downloading optimization device according to the above embodiment of the present application may also have the following additional technical features:

[0020] In one embodiment of the present application, the parsing module is further used to, when using a function to generate a waveform, if the length of the waveform does not meet a preset condition, automatically fill it with zeros during parsing so that its length meets the preset condition, so that the lengths of the waveforms involved in the operation are consistent; and after parsing all basic waveforms edited by the user, send them to the hardware for storage in a first preset format, wherein a storage table is established according to the start address and end address of each waveform.

[0021] In one embodiment of the present application, the parsing module is further used to parse the number of sequences, the composition structure of the sequences and the sequence playback mode when using ADVS and SEQ types, specifically: the waveform playback order of the sequence is parsed according to the ADVS and SEQ types, the subsequences and the number of sequence loops are not expanded, and the waveform playback order is sent to the hardware for storage in a second preset format; the number of sequences and subsequences is parsed according to the ADVS and SEQ types, the number of sequence loops is not expanded, and the sequence of composition is sent to the hardware for storage in a third preset format.

[0031] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] The following describes the AWG waveform editing and downloading optimization method and device proposed in accordance with the embodiments of the present application with reference to the accompanying drawings. First, the AWG waveform editing and downloading optimization method proposed in accordance with the embodiments of the present application will be described with reference to the accompanying drawings.

[0033] Specifically, Figure 1 A flowchart of an AWG waveform editing and downloading optimization method provided in an embodiment of the present application.

[0034] like Figure 1 As shown, the AWG waveform editing and downloading optimization method includes the following steps:

[0035] In step S101, the WAVE set is edited based on the preset function library, and the play order of the sequence is defined by the preset external command SEQ, so that the sequence defined by the ADVS statement and the SEQ statement is assigned to the corresponding channel for waveform editing.

[0036] It is understandable that if Figure 2 As shown, first edit the waveform data. The waveform editing of the arbitrary waveform generator mainly includes global constant settings, basic function library usage and sequence generation. Among them, the basic function library contains some common waveform generation functions, such as sine signals, Gaussian signals, etc. The library can be expanded according to user needs and is not specifically limited here. Several types are introduced below:

[0037] 1. WAVE

[0038] The WAVE type is used to represent an independent waveform. There are three ways to generate a waveform: one is to directly specify the voltage value of each sampling point, the second is through a file, and the third is through a built-in function.

[0039] Generate a waveform by directly specifying the voltage value of each sampling point through list data. The unit of voltage value is mV, and the range is [-500.0, 500.0]. WAVE will automatically linearly encode the voltage value into [0, 65535], where 0mV corresponds to 32768. When constructing WAVE through data list, the mode parameter takes effect, and there are 2 optional values. When Mode = 'Volt' (default value), the data is regarded as voltage value; when Mode = 'Code', the data is regarded as encoded value.

[0040]

[0041] Load WAVE data through .wave file. The data is required to be a 16-bit unsigned integer of a single WAVE, that is, the encoded data. Each data is the data of a sampling point. You can use a complete absolute path or specify a global directory and then search for files in the directory. It should be noted that relative paths are not supported.

[0042]

[0043] 2. Sin

When the value of Amp is not specified, the value of GAmp is used. When the value of Len is not specified, Len=Fs / Freq is automatically used, rounded down. The frequency Freq must be specified, and the following parameters are optional.

[0060] Loop: Optional, positive integer, number of loops.

[0061] Description: Calculate by Amp*exp(-t*t / (Var*Var))+Offset to generate a Gaussian pulse sequence with the center at Len / 2. When the value of A is not specified, the value of GAmp is used. When the value of Len is not specified, the default sampling range is [-5*Var,5*Var). The variance Var must be specified, and the following parameters are optional.

[0062] Example:

[0063]

[0064] 4. Square

[0065] The function prototype is Square(Len, Mode, Amp, Loop), and its related parameters are explained as follows:

[0066] Len: required, positive integer, the number of points in the square wave cycle;

[0067] Mode: Optional, square wave mode, UP is low first and then high, DOWN is high first and then low;

[0068] Amp: optional, real number, same as above;

[0069] Loop: positive integer, number of square wave cycles.

[0070] Example:

[0071] w1 = Square (16, Mode = UP);

[0072] 5. Triangle

[0073] The function prototype is Triangle(Len, Mode, Amp, Loop), and its related parameters are explained as follows:

[0074] Len: required, positive integer, triangle wave period, unit: ns;

[0075] Mode: optional, triangle wave mode, UP is from low to high, DOWN is from high to low;

[0076] Amp: optional, amplitude, usage is the same as above;

[0080] 6. Wind

[0081] The window function, whose function prototype is Wind (N1, Val1, N2, ..., Nn, Valn), is only used for multiplication with other waveforms (it cannot be downloaded as a waveform). The relevant parameters are explained as follows:

[0082] Nn: points;

[0083] Valn: value 0 or 1.

[0084] Example:

[0085]

[0086] 7. Shift

[0087] Shift the waveform. The function prototype is Shift(Wave,Offset). The related parameters are explained as follows:

[0088] Wave: waveform;

[0089] Offset: The number of points to offset.

[0090] Example:

[0094] Cycle: Delay cycle number (sampling clock cycle * 4)

[0095] Example:

[0096] Delay(1000);

[0097] 9. Combine

[0098] The function prototype is Combine(Wave1, Wave2, ..., WaveN), and its function is to combine multiple waveforms together to form a new sequence.

[0099] Example:

[0100] W4=Combine(W1,W2,W3); # Combine W1,W2,W3 to form a new sequence

[0101] 10. Marker

[0102] The function prototype is Marker(N1, Val1, N2, Val2), and its related parameters are explained as follows

[0103] N1, N2: points;

[0104] VAL1, VAL2: value 0 or 1.

[0105] The Marker function can be used to bind the Marker signal to the corresponding waveform.

[0106] Example:

[0107]

[0108] In addition, the SEQ type and ADVS type are as follows:

[0109] A SEQ contains one or more "subsequences", which are arranged in chronological order. In external trigger mode, the subsequence playback is controlled by the trigger signal.

[0110] SEQ([w1(number of repetitions),…,wn(number of repetitions)])

[0111] Where w1, ..., wn are n WAVEs, n>= 1. The number of repetitions is a positive integer.

[0112] Example:

[0113]

[0114] An ADVS can be generated by calling a SEQ type. ADVS supports "+" and "+=" operations. SEQ (number of cycles). Multiple ADVS can be spliced ​​into one ADVS.

[0115] Example:

[0116]

[0117] In the embodiment of the present application, the user can perform waveform editing in the following three steps:

[0118] A. Use the function library to edit the WAVE collection;

[0119] B. Use SEQ to define the playback order of the sequence;

[0120] C. Assign the sequences defined by ADVS and SEQ to the corresponding channels.

[0121] For example:

[0122]

[0123] In step S102, the WAVE set is parsed, and according to the ADVS and SEQ statements, the subsequence set and the composition of each sequence waveform are parsed to obtain a data file and a description file.

[0124] It is understandable that if Figure 2 As shown, after waveform processing, the waveform data forms two files, a data file (used to store data of multiple waveforms) and a description file (describing channel information, waveform sequence, and number of repetitions); the above two files are stored in the storage unit. Among them, the process of compiling the user-edited statement is: first parse out the user-defined WAVE set {Wave1, Wave2, ..., WaveN}, and then parse out the subsequence {Seq1, Seq2, ..., SeqN} set and the composition of each sequence waveform according to the ADVS and SEQ statements.

[0125] In one embodiment of the present application, parsing a WAVE set includes: when using a function to generate a waveform, if the length of the waveform does not meet a preset condition, then during parsing, automatically padding with zeros so that its length meets the preset condition, so that the lengths of the waveforms involved in the operation are consistent.

[0126] The preset condition may be that the length of the waveform meets multiples of 8. For example, when a function is used to generate a waveform, if the length of the waveform does not meet multiples of 8, zeros are automatically added during analysis to make its length meet multiples of 8. When two waveforms are operated, the shorter waveform is automatically filled with zeros to make the lengths of the waveforms involved in the operation the same.

[0127] The Maker function is used to generate marker signals, which correspond to the waveforms in the waveform set one by one. There are as many marker signals as there are waveforms. During use, some waveforms may have marker signals defined, while others may not. In this case, the marker signals for waveforms that do not have marker signals defined will output 1 by default.

[0128] Further, in one embodiment of the present application, after all basic waveforms edited by the user are parsed, they are sent to the hardware for storage in a first preset format, wherein a storage table is established according to the start address and end address of each waveform.

[0129] Among them, the first preset format can be the format of the example in Table 1. Taking this as an example, after the software parses all the basic waveforms edited by the user, it is sent to the hardware for storage in the format defined in the following table. The starting address and ending address of each waveform are stored in a table established by the software to facilitate subsequent processing and calling.

[0130] Table 1

[0131]

[0132] After the software parses the Marker signal edited by the user, it is sent to the hardware for storage in the format defined in Table 2. The software creates a table to store the start address and end address of each Maker signal to facilitate subsequent processing and calling. It should be noted that the Marker signal is stored in the same way as the waveform.

[0133] Table 2

[0134]

[0135] Furthermore, in one embodiment of the present application, parsing the composition of the subsequence set and each sequence waveform further includes: when using ADVS and SEQ types, parsing the number of sequences, the composition structure of the sequences and the sequence playback mode, wherein the waveform playback order of the sequence is parsed according to the ADVS and SEQ types, the number of subsequences and sequence loops is not expanded, and the waveform playback order is sent to the hardware for storage in a second preset format; parsing the number of sequences and subsequences according to the ADVS and SEQ types, the number of sequence loops is not expanded, and the order of the composition is sent to the hardware for storage in a third preset format.

[0136] It is understandable that if Figure 3 As shown, when using ADVS and SEQ types, the software needs to parse the number of sequences, the composition structure of the sequences, and the sequence playback method. It is mainly divided into the following steps:

[0137] First, the basic waveform playback order contained in the sequence is parsed according to the ADVS and SEQ types, the subsequence and the number of cycles of the sequence are not expanded, and the waveform playback order is sent to the hardware for storage in the format of Table 3. Among them, the second preset format can be the format of Table 3 example.

[0138] Table 3

[0139]

[0140]

[0141] Among them, enabling does not require repetition times.

[0142] Then, the number of sequences and subsequences contained therein is parsed according to the ADVS and SEQ types, the number of cycles of the sequence is not expanded, and the sequence of components is sent to the hardware for storage in the format of Table 4. Among them, the third preset format can be the format of the example in Table 4.

[0143] Table 4

[0144]

[0145] The waveform example analysis example is as follows:

[0146]

[0147] In addition, the edited waveform timing diagram is as follows Figure 4 shown.

[0148] It should be noted that before downloading to the hardware, step S103 needs to be executed.

[0149] In step S103, the number of data interface channels and storage capacity of the hardware are extracted. When the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the hardware storage capacity, the corresponding waveform set and sequence playback mode are downloaded to the hardware for execution according to the OUT assignment.

[0150] It is understandable that if Figure 2 As shown, the processing module of the software extracts the number of data interface channels and storage capacity of the hardware. When the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the hardware and the waveform storage capacity is less than or equal to the hardware storage capacity, the data is sent down. The hardware may be an external control device.

[0151] In addition, there are four types of OUT: OUT1, OUT2, OUT3 and OUT4, which correspond to the output of four channels respectively. Each channel can send and receive different waveforms.

[0152] According to the AWG waveform editing and downloading optimization method proposed in the embodiment of the present application, the waveform data is edited and processed to obtain a data file and a description file. The download can only be performed when the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the hardware storage capacity. Therefore, a smaller memory can be occupied when storing the waveform, and there will be negative feedback before the data is sent, which effectively avoids data errors or exceeds the receiving range of the external device, resulting in the loss of the waveform file.

[0153] Next, the AWG waveform editing and downloading optimization device proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0154] Figure 5 It is a block diagram of an AWG waveform editing and downloading optimization device according to an embodiment of the present application.

[0155] like Figure 5As shown, the AWG waveform editing and downloading optimization device 10 includes: an editing module 100 , a parsing module 200 and a processing module 300 .

[0156] Among them, the editing module 100 is used to edit the WAVE set based on the preset function library, and define the playback order of the sequence through the preset external command SEQ, so as to assign the sequence defined by the ADVS statement and the SEQ statement to the corresponding channel for waveform editing; the parsing module 200 is used to parse the WAVE set, and according to the ADVS and SEQ statements, parse the composition of the subsequence set and each sequence waveform to obtain the data file and the description file; the processing module 300 is used to extract the number of data interface channels and the storage capacity of the hardware. When the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the hardware storage capacity, according to the OUT assignment, the corresponding waveform set and sequence playback mode are downloaded to the hardware for execution. The device 10 of the embodiment of the present application can occupy a smaller memory when storing waveforms, and there will be negative feedback before the data is sent, which effectively avoids data errors or exceeds the receiving range of the external device to cause the waveform file to be lost.

[0157] In one embodiment of the present application, the analysis module 200 is further used to, when using a function to generate a waveform, if the length of the waveform does not meet the preset conditions, automatically fill it with zeros during analysis to make its length meet the preset conditions, so that the lengths of the waveforms involved in the operation are consistent; and after parsing all the basic waveforms edited by the user, send them to the hardware for storage in a first preset format, wherein a storage table is established according to the start address and end address of each waveform.

[0158] In one embodiment of the present application, the parsing module 200 is further used to parse the number of sequences, the composition structure of the sequences and the sequence playback mode when using ADVS and SEQ types, specifically: the waveform playback order of the sequence is parsed according to the ADVS and SEQ types, the subsequences and the number of sequence loops are not expanded, and the waveform playback order is sent to the hardware for storage in a second preset format; the number of sequences and subsequences is parsed according to the ADVS and SEQ types, the number of sequence loops is not expanded, and the sequence of composition is sent to the hardware for storage in a third preset format.

[0159] It should be noted that the above explanation of the embodiment of the AWG waveform editing and downloading optimization method is also applicable to the AWG waveform editing and downloading optimization device of this embodiment, and will not be repeated here.

[0160] According to the AWG waveform editing and download optimization device proposed in the embodiment of the present application, the data file and the description file are obtained after the waveform data is edited and processed. The download can only be performed when the number of data interface channels used by the description file is less than or equal to the number of data interface channels of the external device and the capacity of the data file is less than or equal to the hardware storage capacity. Therefore, a smaller memory can be occupied when storing the waveform, and there will be negative feedback before the data is sent, which effectively avoids data errors or exceeds the receiving range of the external device, resulting in the loss of the waveform file.

[0161] This embodiment also provides an electronic device, including: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are configured to execute the AWG waveform editing and downloading optimization method as described in the above embodiment.
