Description

Technical Field

[0001] The present invention relates to the field of electronic design automation technology, and in particular to a method, device, equipment, medium and product for processing simulation waveform data. Background Art

[0002] In the early stages of electronic design automation (EDA) verification, software simulation is a key step in generating waveform data and verifying design logic. With the rapid development of Internet technology, online real-time debugging based on the Internet is of great significance for improving work efficiency and optimizing test processes.

[0003] In the prior art, in the process of network-based waveform display, users often need to zoom in and out on the waveform graph in order to observe the data details at different levels in more detail. Each zoom requires re-pulling a large amount of waveform data from the server and drawing and updating it on the client. In the zooming process, the existing data is usually scaled, resulting in a significant decrease in image quality. Frequent data requests and redrawing operations often cause obvious freezes in the interface, affecting the user's visual experience. In addition, with the increasing complexity of chip design, the amount of waveform data generated by simulation has also surged. Limited by network bandwidth, loading and transmitting these huge data sets often leads to significant delays, which in turn causes visual freezes in the waveform display, which not only affects the user's interactive experience, but also reduces the efficiency of real-time waveform rendering.

[0041] Embodiment 1

[0042] Figure 1 This is a flowchart of a method for processing simulation waveform data provided in the first embodiment of the present invention. This embodiment can be applied to the case where a corresponding waveform image and waveform data are sent to a client in response to a waveform loading request sent by a client. The method can be executed by a processing device for simulation waveform data. The processing device for simulation waveform data can be implemented in the form of hardware and / or software, and can generally be configured in a server, or in the form of an independent device entity, and communicated with the server. Figure 1 As shown, the method includes:

[0043] S110 , obtaining the generated target waveform data, and performing layered processing on the target waveform data according to a preset image zoom level to obtain a plurality of layered images.

[0044] In the embodiment of the present invention, the target waveform data can be specifically understood as: waveform data generated during circuit simulation or signal processing, used to analyze and verify whether the circuit design meets expectations. The preset image zoom level can be specifically understood as: when displaying or processing an image, the preset level of zooming in or out determines the size of the image when displayed relative to the original size, for example, when viewing a waveform, zoom in to view the subtle features of the waveform, and zoom out to view the overall trend and changes of the waveform. The layered image can be specifically understood as: the target waveform data is processed according to the preset image zoom level to generate the corresponding image.

[0045] Specifically, in the process of layering the target waveform data according to the preset image zoom level, first, the preset image zoom level needs to be determined. For example, if the zoom ratio is 2, it means that the waveform needs to be enlarged twice to increase its resolution; if the zoom ratio is 0.5, it means that the waveform needs to be reduced by half to reduce its resolution. According to the zoom ratio, the target waveform data is sampled. If it is enlarged, the data points can be increased by interpolation methods (such as nearest neighbor interpolation or bilinear interpolation, etc.); if it is reduced, the data can be compressed by alternate row and column processing to reduce the data points. According to the zoom ratio, multiple layered images are generated. Each layered image represents a view of the waveform data at different zoom levels, allowing users to view the subtle features of the waveform or preview the overall trend at different levels. The obtained multiple layered images can be stored in the server in the form of segmented directories, and all scaled images are placed in the directory and numbered, such as i-1-50, where i represents the image, 1 represents the image sequence number, and 50 represents the zoom multiple corresponding to the image. The client can subsequently request the server to obtain the corresponding image with the sequence multiple.

[0046] S120 , segmenting the target waveform data according to a preset time segmentation rule to obtain segmented data.

[0047] In the embodiment of the present invention, the preset time segmentation rule can be specifically understood as: the preset rule for segmenting waveform data into multiple time segments can be based on a fixed time interval (for example, every 100 milliseconds is divided into a data segment), or can be based on a specific event or condition (for example, the rising edge or falling edge of the signal). According to specific usage requirements, the preset time segmentation rule can be used. For example, if it is necessary to pay attention to the behavior of the signal in a specific time period, or it is necessary to analyze the changes of the signal before and after a specific event, segmentation can be performed based on a specific event or condition.

[0048] Segmented data can be specifically understood as: for each preset zoom level, the target waveform data is processed according to the established time period segmentation rules to obtain data fragments in each time period. Each part contains a subset of the original waveform data, corresponding to a specific time period. The segmented data can be analyzed separately, or compared with data from other time periods, or multiple segmented data can be combined and displayed to display or identify waveform patterns, trends or anomalies. The obtained segmented data can be stored in the waveform directory of the server in the form of a binary file and labeled, for example, i-1-1, where i represents the picture, i-1 represents the picture sequence number corresponding to the segmented data, i-1-1 represents the first segmented data corresponding to the i-1 picture, each layered picture corresponds to one or more segmented data, and the client can subsequently use the sequence number to request the server to obtain the segmented data corresponding to the picture.

[0049] S130 . In response to the waveform loading request sent by the client, extract the target layered picture and the target segmented data contained in the waveform loading request, and obtain at least one associated layered image and at least one associated segmented data matching the target layered picture and the target segmented data.

[0050] In the embodiment of the present invention, the waveform loading request can be specifically understood as: a request sent by the client to the server, which can include a picture of a specific zoom level that is desired to be loaded, that is, a target layered picture, and information of one or more specific segments that are desired to be viewed (generally, all segmented data under the layer corresponding to the target layered picture), that is, one or more target segmented data. The associated layered image can be specifically understood as: a layered image related to the zoom level of the target layered image. The associated segmented data can specifically be: one or more segmented data corresponding to each associated layered image.

[0051] Specifically, the target layered image and target segmented data requested by the client can be obtained according to the label. In order to improve the smoothness of the user viewing the waveform and reduce the sense of lag when switching the zoom ratio, at least one of the multiple layered images of adjacent resolutions in the direction of increasing and decreasing resolution corresponding to the target layered image can be obtained according to the label as an associated layered image, and one or more associated segmented data related to each associated layered image can be obtained according to the label.

[0052] S140, executing the operation of sending the target layered image and the target segmented data to the client, and after completing the sending, continuing to execute the operation of sending at least one associated layered image and at least one associated segmented data to the client, so as to meet the client's needs in advance.

[0053] Specifically, after the server completes sending the requested target layered image and target segmented data to the client, it also sends at least one associated layered image and at least one associated segmented data as data that the client may need to further analyze or compare. It can not only respond to the current request, but also take into account the possible subsequent needs of the client, so that the information that may be needed is provided before the client explicitly requests this data, thereby improving the user experience and reducing waiting time.

[0054] The technical solution of the embodiment of the present invention is to obtain the generated target waveform data, perform layered processing on the target waveform data according to the preset image zoom level, and obtain multiple layered images; perform segmented processing on the target waveform data according to the preset time period segmentation rule, and obtain segmented data; in response to the waveform loading request sent by the client, extract the target layered image and target segmented data contained in the waveform loading request, and obtain at least one associated layered image and at least one associated segmented data matching the target layered image and the target segmented data; perform the operation of sending the target layered image and the target segmented data to the client, and after completing the sending, continue to perform the operation of sending at least one associated layered image and at least one associated segmented data to the client, so as to meet the client's needs in advance. The pre-processing of waveform data layering and segmentation ensures the image clarity when displayed at different levels. Through the mechanism of advanced sending of associated data, the amount of data transmitted per unit time is reduced, and the efficiency of real-time waveform rendering and user experience are improved.

[0055] Further, based on the above embodiments, before the target waveform data is layered according to the preset image zoom level, the following may be included:

[0056] Traverse the generated waveform data and check the continuity of the waveform data;

[0057] If discontinuous jumps or breaks are found on the waveform graph, they are repaired using a preset waveform fitting method and used as target waveform data.

[0058] Specifically, for each data point, its value is compared with the value of the previous data point to check whether it is within the continuity standard. For example, a threshold value can be set. If the difference between the data points exceeds the threshold value, it is considered discontinuous, or an edge detection algorithm (such as the Canny edge detection algorithm, etc.) is used to check the continuity of the waveform data. When discontinuous jumps or breaks are detected on the waveform graph, this section is marked as abnormal data, so that it can be marked and distinguished by color or horizontal dotted lines when the client loads it later.

[0059] Then, the discontinuous part of the waveform data is repaired by a preset waveform fitting method, which can be repaired by a Gaussian fitting method. By adjusting the amplitude parameter, peak position parameter and standard deviation parameter (corresponding to the width of the waveform) of the Gaussian function, the Gaussian curve is matched with the actual waveform data. Through optimization algorithms such as nonlinear least squares, the amplitude, peak position and standard deviation parameter values ​​are iteratively updated to minimize the residual sum of squares until the parameter update change is less than the preset threshold or the residual sum of squares decreases less than the preset threshold, that is, the convergence condition is reached. The fitted Gaussian function can be used to generate new data points in these discontinuous areas to repair the waveform data, and these new data points are marked for subsequent client loading through another color or horizontal dotted line and other forms of marking and distinguishing. For the client, it is possible to distinguish abnormal data from normal data through visual marks such as color or horizontal dotted line. Users can more easily identify and understand the characteristics of waveform data, thereby making more accurate decisions, enhancing data visualization and user experience.

[0060] Optionally, based on the above embodiments, obtaining at least one associated layered image and at least one associated segmented data matching the target layered image and the target segmented data may include:

[0061] According to the picture resolution of the target layered picture, acquiring at least one associated picture resolution along a direction of increasing and / or decreasing picture resolution, and acquiring candidate layered images matching each associated resolution;

[0062] According to the time period in which the target segmented data is located, obtaining at least one associated time period along the time rewinding and / or extending direction, and obtaining candidate segmented data matching each associated time period;

[0063] and matching each candidate layered image and each candidate segmented data with a sent cache queue of the client, and filtering out the candidate layered images and candidate segmented data existing in the sent cache queue;

[0064] The sent cache queue stores a set number of layered images and segmented data that were recently sent to the client;

[0065] The candidate layered images and the candidate segmented data after the filtering operation are respectively determined as the associated layered images and the associated segmented data.

[0066] In the embodiment of the present invention, the associated image resolution can be specifically understood as: other resolutions associated with the target layered image resolution, which can be a resolution larger than the target layered image resolution or a resolution smaller than the target layered image resolution. The alternative layered image can be specifically understood as: an image generated on the basis of the target layered image to provide options of different resolutions (associated image resolutions). The associated time period can be specifically understood as: other time periods associated with the time period where the target segmented data is located, which can be a time period earlier than the time period where the target segmented data is located or a time period later than the time period where the target segmented data is located. The alternative segmented data can be specifically understood as: segmented data generated on the basis of the target segmented data to provide options of different time periods (associated time periods). The alternative layered image corresponds to one or more alternative segmented data, which are used to display alternative layered images corresponding to different resolutions, thereby realizing segmented viewing of images of each resolution.

[0067] Typically, the client can determine the resolution of the associated image based on the waveform viewing rules corresponding to the application type of the server. For example, for a waveform generated by a specific type of server, after requesting the target layered image of the current zoom ratio, the client will most likely continue to request one or more layered images with resolutions determined along the direction of increasing or decreasing the image resolution, and these resolutions can be used as the resolution of the associated image. Similarly, the client can determine the associated time period based on the waveform viewing rules corresponding to the application type of the server, and send a waveform loading request that matches the associated layered data and the associated segmented data to the server.

[0068] In a specific example, the server can dynamically adjust the waveform data transmission strategy based on the client's request history and behavior pattern for the same type of simulation waveform. For example, if the server finds that a client is likely to request a waveform with a resolution of 1920×1080 after requesting to view a waveform with a resolution of 800x600, the server can proactively send the waveform data with a resolution of 1920×1080 to the client.

[0069] Specifically, before sending the candidate layered images and candidate segmented data, it will check whether these resources already exist in the client's sent cache queue. If it is found that a resource already exists, then this resource will be filtered out and no longer sent repeatedly, and the resources that are not filtered out will be used as the associated layered images and associated segmented data. By filtering out existing resources, unnecessary data transmission is reduced, bandwidth is saved, and network efficiency is improved. Through the mechanism of sending associated data in advance, the amount of data transmitted per unit time is reduced, and the efficiency of real-time waveform rendering and user experience are improved.

[0070] Embodiment 2

[0071] Figure 2 This is a flowchart of another method for processing simulated waveform data provided in the second embodiment of the present invention. This embodiment is applicable to the case where waveform images and waveform data in the cache or waveform images and waveform data sent by the server are loaded and displayed. The method can be executed by a processing device for simulated waveform data. The processing device for simulated waveform data can be implemented in the form of hardware and / or software, and can generally be configured in the client, or in the form of an independent device entity, and communicated with the client. Figure 2 As shown, the method includes:

[0072] S210: Obtain waveform loading requirements.

[0073] In the embodiment of the present invention, the waveform loading requirement may be specifically understood as: the waveform viewing resolution and segmentation requirement selected by the user on the client.

[0074] S220, check whether the local cache contains the target layered image and target segmented data corresponding to the waveform loading requirement. If not, execute S230; if yes, execute 250.

[0075] S230, sending a waveform loading request matching the waveform loading requirement to the server, and upon receiving the target layered image and target segmented data fed back by the server, performing client loading and display on the target layered image and target segmented data. Execute S240.

[0076] Specifically, the client renders and loads the target layered images and target segmented data obtained from the server. In addition, the discontinuous parts of the waveform and the fitted theoretical value parts can be distinguished and loaded with different colors or line types according to the labels. In order to realize the interactive function of the waveform graph, event listeners can also be added to process user input. For example, the zoom function of the waveform graph can be realized by listening to the mouse wheel event, and the translation function of the waveform graph can be realized by dragging the event. In addition, additional interactive elements can be integrated, such as mouse hover prompts to display detailed data, waveform type selectors, and export functions to enhance the user experience.

[0077] S240: When receiving at least one associated layered image and at least one associated segmented data fed back in advance by the server for the target layered picture and the target segmented data, locally cache the associated layered image and the associated segmented data.

[0078] Specifically, the server predicts other related resources (i.e., associated layered images and associated segmented data) that the client may need based on the target layered image and target segmented data, and sends these resources to the client in advance. When the client receives at least one associated layered image and at least one associated segmented data pre-provided by the server, the client stores these associated resources in the local cache for quick access and future use.

[0079] S250: Obtain the corresponding target hierarchical data and target segmented data in the cache for loading and displaying on the client.

[0080] The technical solution of the embodiment of the present invention obtains the waveform loading requirement, checks whether the target layered image and target segmented data corresponding to the waveform loading requirement are stored in the local cache; if not, sends a waveform loading request matching the waveform loading requirement to the server, and when receiving the target layered image and target segmented data fed back by the server, loads and displays the target layered image and target segmented data on the client; when receiving at least one associated layered image and at least one associated segmented data fed back in advance by the server for the target layered image and target segmented data, caches the associated layered image and associated segmented data locally; if yes, obtains the corresponding target layered data and target segmented data in the cache for loading and displaying on the client. Implementing the local cache reuse mechanism of waveform data and the advance cache mechanism of associated data on the client can quickly display the viewed waveform data and associated data without repeated requests, significantly reducing the data transmission requirements of the server, achieving a smooth user experience, and improving the efficiency of real-time waveform rendering.

[0081] Further, based on the above embodiments, after obtaining the corresponding target hierarchical data and target segmented data in the cache for loading and displaying on the client, the following may also be included:

[0082] Checking whether at least one associated hierarchical data and at least one associated segmented data matching the target hierarchical data are stored in the cache;

[0083] If not, a waveform loading request matching the associated hierarchical data and the associated segmented data is sent to the server to obtain the associated hierarchical data and the associated segmented data in advance.

[0084] Specifically, the client first checks whether there are associated hierarchical data and associated segmented data matching the target hierarchical data in its local cache. This is to determine whether additional waveform data that the user may need has been stored to avoid repeated request transmission. If the required associated hierarchical data and associated segmented data are not found in the local cache, the client will actively send a request to the server to obtain these data, that is, the client has predicted and requested them before the user explicitly requests them. Typically, the client can determine the resolution of the associated image based on the waveform viewing rules corresponding to the application type of the server. Similarly, the client can determine the associated time period based on the waveform viewing rules corresponding to the application type of the server, and send a waveform loading request matching the associated hierarchical data and associated segmented data to the server. By obtaining and caching the associated data in advance, the time users wait for data loading can be reduced. Since some requests have been processed in advance in the background, the number of network requests caused by user operations is reduced, and the efficiency of real-time waveform rendering and user experience are improved.

[0085] Specific application scenarios

[0086] With the rapid development of Internet technology, more and more design work and test processes are being carried out over the Internet, and the demand for online real-time debugging based on the Internet is becoming increasingly important. In the process of network-based waveform display, users usually need to frequently zoom in and out on the waveform graph in order to view details at different levels. Each zoom operation requires re-acquiring a large amount of waveform data from the server and redrawing it on the client. However, frequent data acquisition and redrawing operations will cause obvious visual freezes, especially in an environment with limited network bandwidth, where the delay is more prominent, seriously affecting the user's smooth experience. In addition, if the waveform data is not resampled from the server during the zoom process, but the existing data is directly zoomed, the image quality will be significantly reduced, blurring will occur, and the details will not be clear, resulting in information loss when viewing the details, and the need for refined debugging cannot be met. In order to solve the above problems, an embodiment of the present invention proposes a method for processing simulation waveform data, which may specifically include:

[0087] 1. Simulation waveform data generation

[0088] The system outputs the initial waveform data file according to the EDA simulation tool.

[0089] 2. Waveform data preprocessing

[0090] The server pre-processes the waveform data, traverses the generated waveform data, and checks the continuity of the waveform data. If discontinuous jumps or breaks are found on the waveform graph, they are repaired using a preset waveform fitting method.

[0091] The waveform data is processed in layers and divided into different levels of data blocks according to the zoom level and unit time period to meet different zoom level and time period requirements. This preprocessing scheme generates two data formats: binned static images and segmented adjustable waveform data.

[0092] Among them, the binned images refer to the generation of images of multiple resolutions according to different zoom levels of waveform data, and each zoom level corresponds to a level of image data. These images are used for preview when reducing or zooming in the waveform display, providing a fast and low-latency viewing experience without the user having to load the complete data level by level.

[0093] Segmented waveform data refers to data division based on the time period of the waveform, dividing the original waveform data into multiple continuous small segments to adapt to the display requirements of different time periods. Each segment of waveform data corresponds to a specific time window. When the user needs to view a high-precision waveform in a specific time period, the corresponding segmented data can be directly called without loading the complete waveform.

[0094] 3. Storage of file-by-file images and segmented data

[0095] The pre-processed waveform data static images and segmented waveform data are cached to the server in preparation for subsequent on-demand loading.

[0096] 4. Client requests data

[0097] The user initiates a waveform data viewing request on the client, including operations such as zooming and panning.

[0098] 5. Check the client cache

[0099] Check whether the client already has a waveform data cache for the requested gear. If so, and the cache contains waveform data for the requested gear along the direction of increasing and decreasing the image resolution, jump to step 8 to directly read the local cache.

[0100] 6. Get data from the server

[0101] If the client cache is missing, the system retrieves the corresponding graded or segmented waveform data from the server according to the request and returns it to the client.

[0102] According to the picture resolution of the corresponding bin, at least one associated picture resolution is obtained along the direction of increasing and decreasing picture resolution, and candidate layered images matching each associated resolution are obtained.

[0103] According to the time period in which the corresponding segmented data is located, at least one associated time period is obtained along the time rewinding and extending directions, and candidate segmented data matching each associated time period is obtained.

[0104] Each candidate layered image and each candidate segmented data are matched with the sent cache queue of the client, and the candidate layered images and candidate segmented data existing in the sent cache queue are filtered out. The sent cache queue stores a set number of layered images and segmented data recently sent to the client.

[0105] The candidate layered images and the candidate segmented data after the filtering operation are respectively determined as the associated layered images and the associated segmented data.

[0106] The system retrieves the waveform data of the associated layered image and the associated segmented data from the server and returns them to the client.

[0107] 7. Client cache data

[0108] The newly acquired waveform data is cached on the client side to quickly respond to subsequent requests for the same gear and reduce transmission delays.

[0109] 8. Waveform data rendering

[0110] The client renders the acquired waveform data and displays it in the browser.

[0111] A method for processing simulation waveform data proposed in an embodiment of the present invention reduces the computing and transmission pressure of the server by pre-processing the waveform data in layers and segments in advance, and can meet the flexible needs of users under different zoom and time precisions, especially under the condition of limited network bandwidth, which significantly reduces the data transmission delay, so that the waveform data can provide a clear and fast response experience under various display conditions. By utilizing the layered design of data, the client can obtain data of corresponding precision at different zoom levels without having to obtain all of it from the server, which reduces the amount of data transmitted. Under the same bandwidth conditions, the transmission speed is faster than the traditional full data transmission method, which greatly improves the efficiency of real-time waveform rendering.

[0112] The hierarchical segmented cache strategy effectively copes with different frequent scaling and repeated requests, improving the scalability of the real-time simulation environment. Users can perform real-time waveform backtracking and multi-scale viewing, which is particularly suitable for multi-level waveform analysis scenarios such as complex chip design verification.

[0113] Implement a local cache reuse mechanism for waveform data on the client. When a user browses a waveform, the client loads and caches the corresponding segmented images and segmented waveform data based on the user's zoom level and time window. When the user returns to the zoom level or time period that has been viewed, the system can read the data directly from the local cache without repeatedly requesting it from the server. This cache reuse mechanism has the following characteristics:

[0114] Through local caching, the client can quickly display the viewed waveform data without repeated requests, significantly reducing the server's data transmission requirements and alleviating the server's burden; with the support of local caching, the client can achieve "zero delay" loading, significantly improving the user's smooth experience, especially in an environment with limited network bandwidth, it can significantly reduce delays; through the cache reuse mechanism, the client does not need to frequently redraw the loaded waveform data, greatly reducing the jamming caused by data requests, and achieving a smooth and continuous waveform viewing experience, especially in high-complexity waveform display, compared with the existing dynamic data request method, it significantly improves the user's control over waveform details and viewing smoothness.

[0115] This collaborative design of the server and client not only ensures efficient data transmission but also improves the scalability of the system. It is especially suitable for distributed debugging environments and simulation environments with low latency requirements.
