Description

Technical Field

[0001] This invention relates to the field of digital waveform viewing and debugging technology, and in particular to a GUI (Graphical User Interface) display method, device, medium and product for digital waveforms. Background Technology

[0002] Chip verification typically involves examining chip simulation waveforms to pinpoint problems. With advancements in integrated circuit technology, chip designs are becoming increasingly larger and more complex. To locate problems more effectively and quickly, the length of the simulation waveform data collected is constantly increasing, often exceeding one million clock cycles.

[0003] In the field of digital waveform display and debugging, scaling up and down waveforms is the most common debugging method. Waveform scaling typically uses a linear scaling algorithm. According to the algorithm's principle, when the waveform is scaled down to a certain extent, a horizontal axis (typically the X-axis) coordinate on the screen represents the waveform over a period of time. If conventional graphics drawing methods are used, the values ​​of all moments within this time period need to be plotted at this horizontal axis coordinate to accurately reflect the waveform's characteristics. In other words, multiple waveforms are superimposed on a single horizontal axis coordinate. When the waveform duration reaches millions of seconds, waveform drawing will exhibit stuttering, severely impacting the user experience. Summary of the Invention

[0004] This invention provides a GUI display method, device, medium, and product for digital waveforms, to solve the problem that when scaling and displaying digital signals generated during chip simulation, repeated drawing on the same pixel on the display interface causes stuttering in waveform scaling and display, resulting in low debugging efficiency.

[0009] According to another aspect of the present invention, a GUI display device for digital waveforms is provided, comprising:

[0010] The waveform drawing resource acquisition module is used to respond to the request to display the target digital waveform in the target display coordinate system in the GUI, and to acquire the time window that matches the target digital waveform and the pixel window that matches the time coordinate axis in the target display coordinate system.

[0011] The digital waveform value set acquisition module is used to calculate the digital waveform value set corresponding to each pixel in the time coordinate axis when it is determined from the time window and pixel window that the target digital waveform cannot be completely drawn in the target display coordinate system.

[0012] The digital waveform drawing module is used to draw the target digital waveform in the target display coordinate system in the GUI based on the set of digital waveform values ​​corresponding to each pixel point in the time coordinate axis.

[0018] According to another aspect of the present invention, a computer program product is also provided, including a computer program that, when executed by a processor, implements the steps of the method as described in any embodiment of the present invention.

[0019] The technical solution of this invention can, in response to a request to display a target digital waveform in a target display coordinate system within a GUI, acquire a time window matching the target digital waveform and a pixel window matching the time axis in the target display coordinate system. When it is determined, based on the time window and pixel window, that the target digital waveform cannot be completely drawn in the target display coordinate system, a set of digital waveform values ​​corresponding to each pixel point on the time axis is calculated. Based on the set of digital waveform values ​​corresponding to each pixel point on the time axis, the target digital waveform is drawn in the target display coordinate system within the GUI. This technical solution, by sampling and drawing the target digital waveform values ​​according to the target display coordinate system, significantly improves the efficiency of digital waveform scaling operations and enhances the convenience of debugging digital waveforms in chip simulation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0033] Example 1

[0034] Figure 1 This is a flowchart of a GUI display method for digital waveforms provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the digital signal waveform to be observed is scaled (especially reduced) on a GUI during chip simulation. This method can be executed by a GUI display device for digital waveforms, which can be implemented in hardware and / or software and is generally configured in electronic devices with data processing capabilities. Figure 1 As shown, the method includes:

[0035] S110. In response to a request to display the target digital waveform in the target display coordinate system of the GUI, obtain a time window that matches the target digital waveform and a pixel window that matches the time axis in the target display coordinate system.

[0036] The target digital waveform can be understood as the digital signal acquired from a specific detection location in the chip simulation system at multiple acquisition time points during the chip simulation process, and can be described by multiple signal values ​​acquired at each acquisition time point.

[0037] Specifically, in Figure 2 The diagram shows a schematic representation of a target digital waveform. (For example...) Figure 2 As shown, the target digital waveform is confined to the time interval defined by [T1, T2], and the signal value at different time points can be 0 (corresponding to a low-level signal amplitude) or 1 (corresponding to a high-level signal amplitude). Accordingly, the time window matching the target digital waveform can be understood as the time interval defined by the start and end times of the target digital waveform. For example, Figure 2 The [T1, Tn] shown is the time window that matches the target digital waveform.

[0038] The target display coordinate system can be understood as a coordinate system used to visualize the target data waveform. Since the target digital waveform can be described by multiple signal values ​​(also called digital waveform values) collected at multiple time points, the target display coordinate system accordingly includes a signal value coordinate axis and a time coordinate axis. That is, the time coordinate axis refers to the horizontal coordinate axis in the coordinate system used to display the digital waveform, representing the time scale of the digital waveform display.

[0039] Since the target display coordinate system is displayed in the defined graphical user interface (GUI), and this target display coordinate system occupies a defined image size within the GUI, the time axis also occupies a defined image size. Correspondingly, the pixel window matching the time axis in the target display coordinate system can be understood as the size of the image pixel area defined by the start and end points of the time axis. In other words, this pixel window can refer to the waveform coordinate system display window in the digital waveform display coordinate system that corresponds to the horizontal time axis, using pixel values ​​from the GUI as the horizontal axis to indicate the scale.

[0040] In practice, once the image display scale of the target display coordinate system in the graphical user interface is determined, the size of the pixel window matching the time axis in the target display coordinate system is also determined accordingly. However, when viewing digital waveforms, users may dynamically update the scaling scale of the digital waveform. Understandably, when viewing a digital waveform within a set-size image area, the larger the magnification ratio selected by the user, the smaller the time window of the target digital waveform displayed in the target display coordinate system; conversely, the larger the zoom-out ratio selected by the user, the larger the time window of the target digital waveform displayed in the target display coordinate system.

[0041] Accordingly, the main problem solved by the technical solutions of the various embodiments of the present invention is that when the user selects a large scaling ratio, causing the pixel window size to be much smaller than the time window size, the data waveform values ​​at multiple time points are repeatedly drawn on the same pixel. Accordingly, the aforementioned target digital waveform can be further understood as the digital waveform with a determined time window size after the original digital signal has been scaled by the user-selected scaling ratio.

[0042] S120. When it is determined from the time window and pixel window that the target digital waveform cannot be completely drawn in the target display coordinate system, calculate the set of digital waveform values ​​corresponding to each pixel point in the time coordinate axis.

[0043] As mentioned earlier, when the pixel window size is greater than or equal to the time window size, only zero or one digital waveform value from the target digital waveform will be drawn at a single pixel on the time axis. In this case, the target digital waveform can be completely drawn within the target display coordinate system, without the need to repeatedly draw digital waveform values ​​from multiple time points at a single pixel. Therefore, drawing the target digital waveform directly in the target display coordinate system is sufficient, without requiring additional operations. Specifically, in Figure 3 The diagram shows a schematic of the effect of a target digital waveform being fully drawn in a pixel window.

[0044] However, when the pixel window size is smaller than the time window size, it means that multiple time points' digital waveform values ​​need to be repeatedly drawn at a single pixel on the time coordinate axis. In this case, the target digital waveform cannot be completely drawn within the target display coordinate system. Therefore, it is necessary to actually adopt the technical solutions of the various embodiments of this invention to avoid repeatedly drawing digital waveform values ​​at multiple time points at a single pixel.

[0045] Specifically, it is necessary to first calculate the set of digital waveform values ​​corresponding to each pixel point on the time coordinate axis.

[0046] It is understandable that the target digital waveform within this time window is composed of multiple digital waveform values. When the scale of the pixel window is smaller than the scale of the time window, it also means that the total number of the aforementioned digital waveform values ​​is greater than the total number of pixels contained in the pixel window. In this case, according to a preset mapping rule, each pixel in the pixel window needs to be assigned one or more digital waveform values ​​to form a set of digital waveform values ​​corresponding to each pixel in the time coordinate axis.

[0047] In a specific example, the set 1 of digital waveform values ​​corresponding to pixel A contains {digital waveform value 1, digital waveform value 2, digital waveform value 3}. In this case, it means that the above digital waveform value 1, digital waveform value 2, and digital waveform value 3 are waveform values ​​that need to be repeatedly drawn under pixel A.

[0048] S130. Based on the set of digital waveform values ​​corresponding to each pixel point in the time coordinate axis, draw the target digital waveform in the target display coordinate system in the GUI.

[0049] It is understandable that drawing the target digital waveform within the target display coordinate system in the GUI can use the corresponding pixels on the time axis of the pixel window as the reference for the horizontal coordinate axis of the waveform drawing. The digital waveform value of the pixel is selected based on the distribution of high and low levels in the set of matching digital waveform values ​​of each pixel. Finally, the entire target digital waveform is drawn based on the digital waveform values ​​of each pixel and its adjacent pixels.

[0050] In this embodiment, since a set of digital waveform values ​​corresponding to each pixel in the time coordinate axis is obtained through pre-screening, only one specific digital waveform value can be selected from each set of digital waveform values ​​and drawn under the corresponding pixel based on the distribution of high and low level values ​​contained in each set of digital waveform values. This effectively avoids the repeated drawing of multiple digital waveform values ​​on the same pixel and effectively reduces the stuttering problem in graphics drawing. It is particularly suitable for application scenarios where the time window length of the target digital waveform to be drawn reaches millions or tens of millions.

[0051] The technical solution of this invention can, in response to a request to display a target digital waveform in a target display coordinate system within a GUI, acquire a time window matching the target digital waveform and a pixel window matching the time axis in the target display coordinate system. When it is determined, based on the time window and pixel window, that the target digital waveform cannot be completely drawn in the target display coordinate system, a set of digital waveform values ​​corresponding to each pixel point on the time axis is calculated. Based on the set of digital waveform values ​​corresponding to each pixel point on the time axis, the target digital waveform is drawn in the target display coordinate system within the GUI. This technical solution, by sampling and drawing the target digital waveform values ​​according to the target display coordinate system, significantly improves the efficiency of digital waveform scaling operations and enhances the convenience of debugging digital waveforms in chip simulation.

[0052] Example 2

[0053] Figure 4 This is a flowchart illustrating a GUI display method for digital waveforms according to Embodiment 2 of the present invention. This embodiment is a specific embodiment based on the above embodiments, including a specific method for drawing the target digital waveform by retrieving its value within a pixel window. For example... Figure 4 As shown, the method includes:

[0054] S410, In response to a request to display the target digital waveform in the target display coordinate system of the GUI, obtain a time window that matches the target digital waveform and a pixel window that matches the time axis in the target display coordinate system.

[0055] S420. Based on the waveform start time and waveform end time in the time window, and the signal sampling interval corresponding to the target digital waveform, determine the set of waveform time points that match the time window, and obtain the total number of time points contained in the waveform time point set.

[0056] In this context, a waveform time point corresponds to a digital waveform value in the target digital waveform, and the digital waveform value includes high level and low level values.

[0057] The waveform start time can be the starting point of the aforementioned time window, and the waveform end time can be the ending point of the aforementioned time window. Specifically, for example... Figure 2 As shown, the start time of this waveform can be specifically T1, and the end time of this waveform can be specifically Tn. The signal sampling interval can be understood as the signal acquisition interval selected when acquiring signals at the detected position during chip simulation, such as 1ms, 2ms, or 5ms.

[0058] As mentioned earlier, the actual acquired target digital waveform is composed of digital waveform values ​​acquired at multiple time points. Therefore, once the time window is determined, for example, 100 seconds, and combined with the signal sampling interval, a set of waveform time points matching the time window can be determined accordingly. The total number of time points in the waveform time point set can be calculated using the formula: (waveform end time - waveform start time) / signal sampling interval.

[0059] Specifically, when plotting the target digital waveform, it is necessary to obtain the time axis range corresponding to the target digital waveform in the target display coordinate system. This range can be determined based on the start and end times of the target digital waveform within the time window. By combining the set of waveform time points matching the time window within the signal sampling interval and the total number of included time points, it can be determined whether the digital waveform value corresponding to each waveform time point is a high-level or low-level value, and thus the corresponding digital waveform value in the target digital waveform can be determined.

[0060] S430. Calculate the total number of pixels contained in the time coordinate system based on the starting and ending pixel sizes of the pixel window on the time axis.

[0061] Here, pixel size can be understood as the pixel coordinate value of a single pixel on the X-axis of the image coordinate system. Correspondingly, the starting pixel size can be understood as the X-axis coordinate value X1 of the starting pixel in the pixel window, and the ending pixel size can be understood as the X-axis coordinate value Xn of the ending pixel in the pixel window. Optionally, the total number of pixels in the time coordinate system can be calculated using the formula Xn-X1.

[0062] S440. If the total number of time points is greater than the total number of pixels, then the target digital waveform cannot be fully drawn within the target display coordinate system.

[0063] Understandably, when drawing a target digital waveform, it is necessary to determine whether the target digital waveform can be completely drawn in the target display coordinate system based on the total number of time points determined by the start and end times of the waveform, and the total number of pixels in the target display coordinate system. If the total number of time points is greater than the total number of pixels, it cannot be completely drawn.

[0064] S450, Calculate the set of digital waveform values ​​corresponding to each pixel point in the time coordinate axis.

[0065] In this embodiment, when the total number of time points is greater than the total number of pixels, it is necessary to first determine which digital waveform values ​​need to be drawn under the same pixel, that is, to determine the set of digital waveform values ​​corresponding to each pixel.

[0066] In an optional implementation of this embodiment, calculating the set of digital waveform values ​​corresponding to each pixel on the time coordinate axis may include:

[0067] S4501. Sequentially obtain one current waveform time point from the waveform time point set.

[0068] Specifically, each waveform time point obtained sequentially from the waveform time point set can be processed as follows, according to the time extension order.

[0069] S4502. Based on the current waveform time point, the starting pixel size and the ending pixel size of the pixel window, call the pre-built coordinate transformation formula to calculate the current pixel point in the pixel window mapped to the time coordinate axis.

[0070] The coordinate transformation formula refers to an algorithm that converts the time coordinate dimension of a digital waveform in a time window into the pixel coordinates of the horizontal coordinate axis in a pixel window. Essentially, it maps the abstract time coordinate axis to specific pixel positions that can be displayed on the screen, allowing the digital waveform to be intuitively drawn on the graphical user interface. The current pixel point refers to the pixel point in the time coordinate axis pixel window corresponding to the current waveform time point.

[0071] In an optional implementation of this embodiment, the existing coordinate transformation function CoordinatesXToPixel can be called, and the current waveform time point T, the starting pixel size X1, and the ending pixel size Xn can be input accordingly. Then, the current pixel point pixelX can be obtained in the pixel window of the time coordinate axis mapped from the current waveform time point T, that is, pixelX = CoordinatesXToPixel(T, X1, Xn).

[0072] As mentioned earlier, since the total number of time points is greater than the total number of pixels, the above mapping method will inevitably result in multiple waveform time point mapping values ​​for the same pixel on the time coordinate axis.

[0073] S4503. Add the digital waveform value at the current waveform time point to the set of digital waveform values ​​corresponding to the current pixel point.

[0074] Understandably, once the mapping relationship between the current waveform time point and the current pixel point is determined, the digital waveform value at the current waveform time point can be added to the set of digital waveform values ​​corresponding to the current pixel point, which can then be used as the basis for drawing the digital waveform values ​​of each pixel point in the target digital waveform diagram.

[0075] S4504. Return to the previous step and execute the operation of sequentially obtaining one current waveform time point from the waveform time point set until all waveform time points in the waveform time point set have been processed to obtain a set of digital waveform values ​​corresponding to each pixel point in the time coordinate axis.

[0076] Understandably, before drawing the target digital waveform, it is necessary to confirm the set of digital waveform values ​​corresponding to each pixel point under the pixel window of the time axis. The waveform time point can be obtained by traversing the set of waveform time points in the order of the above steps as the current waveform time point. The pixel points mapped by each waveform time point are confirmed according to the pre-built coordinate transformation formula, and the set of digital waveform values ​​of the corresponding pixel points is determined, until all waveform time points in the waveform time point set have been traversed and processed.

[0077] S460. Obtain the set of target digital waveform values ​​corresponding to the target pixel in the time coordinate axis, and obtain the previous drawing result executed for the previous pixel of the target pixel.

[0078] The previous drawing result includes the first drawing point value at a first position corresponding to the first height in the signal value coordinate axis of the previous pixel and the target display coordinate system, or the second drawing point value at a second position corresponding to the second height in the signal value coordinate axis of the previous pixel; the first height corresponds to the high level value, and the second height corresponds to the low level value.

[0079] In this context, the target pixel can refer to the pixel currently being processed and having its digital waveform value determined within the time axis pixel window. The target digital waveform value set can refer to the set of digital waveform values ​​corresponding to the target pixel, determined by a pre-built coordinate transformation formula. The signal value coordinate axis can refer to the vertical coordinate axis in the target display coordinate system used to indicate whether the digital waveform value is high or low. The previous pixel can refer to the pixel immediately preceding the target pixel in the time axis pixel window of the target display coordinate system. The first position can refer to the position in the signal value coordinate axis corresponding to a high digital waveform value. The first plotting point value can refer to the high-level digital waveform value represented at the first position. The second position can refer to the position in the signal value coordinate axis corresponding to a low digital waveform value. The second plotting point value can refer to the low-level digital waveform value represented at the second position.

[0080] It is understandable that, in addition to confirming the digital waveform value of the target pixel through the target digital waveform value set, drawing the target digital waveform also requires confirming the drawing result of the adjacent previous pixel. This allows us to determine whether the digital waveform value of each pixel constituting the target digital waveform is high or low, thereby drawing the continuous target digital waveform at the position of the digital waveform value of each pixel in the signal value coordinate axis.

[0081] S470. Based on the inclusion of high and low level values ​​in the target digital waveform value set and the previous drawing result, perform matching point drawing and / or line drawing operations on the target pixel in the target display coordinate system in the GUI.

[0082] It is understandable that the target digital waveform value set corresponding to the target pixel can consist entirely of high-level values ​​or low-level values, or contain both high-level and low-level values. The digital waveform value of the target pixel can be determined according to a pre-set selection strategy based on the specific situation. Furthermore, based on the drawing result of the previous pixel, the position of the digital waveform value of adjacent pixels in the signal value coordinate axis can be determined. This determines the matching point drawing and / or line drawing operation to be performed on the target pixel within the target display coordinate system in the GUI. The target digital waveform... Figure 1 Optional final drawing effects, such as Figure 5 As shown.

[0083] Optionally, based on the inclusion of high and low level values ​​in the target digital waveform value set and the previous drawing result, within the target display coordinate system in the GUI, performing matching point drawing and / or line drawing operations on the target pixels may include:

[0084] If the target digital waveform value set contains a high-level value and the previous drawing result is the first drawing point value, then the target drawing point value is drawn only at the third position corresponding to the first height in the target pixel point and signal value coordinate axis.

[0085] If the target digital waveform value set contains a high-level value, and the previous drawing result is the second drawing point value, then after drawing the target drawing point value at the third position, draw the line connecting the second drawing point value and the target drawing point value.

[0086] The third position can refer to the position corresponding to the first height on the signal value coordinate axis when the target digital waveform value set contains a high-level value. The target pixel value can refer to the target digital waveform value of the target pixel on the signal value coordinate axis, determined based on the level values ​​contained in the target digital waveform value set.

[0087] Specifically, when drawing the target digital waveform, if the target digital waveform value set contains at least one high-level value, and the previous drawing result is a first point value where the digital waveform value is high, then the target point value is drawn only at the third position corresponding to the high level in the target pixel and signal value coordinate axis; that is, a point is drawn only at the third position. If the target digital waveform value set contains at least one high-level value, and the previous drawing result is a second point value where the digital waveform value is low, then after drawing the target point value at the third position corresponding to the high level in the target pixel and signal value coordinate axis, a line is drawn connecting the second point value corresponding to the low level in the target pixel and signal value coordinate axis to the target point value. The drawing effect is as follows: Figure 6 As shown. This completes the drawing of the target digital waveform portion related to the previous drawing result when the target digital waveform value set corresponding to the target pixel contains a high-level value.

[0088] Optionally, based on the inclusion of high and low level values ​​in the target digital waveform value set and the previous drawing result, performing matching point drawing and / or line drawing operations on the target pixels within the target display coordinate system in the GUI may further include:

[0089] If the target digital waveform value set does not contain a high level value, and the previous drawing result is the first drawing point value, then after drawing the target drawing point value at the fourth position corresponding to the second height in the coordinate axis of the target pixel point and the signal value, draw the connection between the first drawing point value and the target drawing point value.

[0090] If the target digital waveform value set does not contain a high-level value, and the previous drawing result is the second drawing point value, then the target drawing point value is drawn only at the fourth position.

[0091] The fourth position can refer to the position corresponding to the second height on the signal value coordinate axis when the target digital waveform value set does not contain a high-level value.

[0092] Specifically, when drawing the target digital waveform, if the target digital waveform value set contains no high-level values ​​and all values ​​are low-level values, and the previous drawing result is the first point value where the digital waveform is high-level, then after drawing the target point value at the fourth position corresponding to the low level in the target pixel and signal value coordinate axis, a line is drawn connecting the first point value corresponding to the high level in the target pixel and signal value coordinate axis to the target point value. If the target digital waveform value set does not contain high-level values, and the previous drawing result is the second point value where the digital waveform is low-level, then the target point value is only drawn at the fourth position corresponding to the low level in the target pixel and signal value coordinate axis; that is, a point is drawn only at the fourth position, and the drawing effect is as follows. Figure 7As shown. This completes the drawing of the target digital waveform portion related to the previous drawing result when all the target digital waveform values ​​corresponding to the target pixel are low-level values.

[0093] Optionally, based on the above embodiments, after obtaining the set of target digital waveform values ​​corresponding to the target pixel points in the time coordinate axis, the method further includes:

[0094] If the target pixel is the first pixel on the time axis, then check whether the target digital waveform value set contains a high level value;

[0095] If so, the target pixel value is drawn only at the third position corresponding to the first height in the target pixel and signal value coordinate axes;

[0096] Otherwise, the target pixel value is drawn only at the fourth position corresponding to the second height in the target pixel and signal value coordinate axes.

[0097] Specifically, when the target pixel is the first pixel on the time axis, drawing can be performed solely based on the level values ​​contained in the target digital waveform value set. If at least one high level value is contained, the target pixel value is drawn only at the third position corresponding to the high level on the target pixel and signal value coordinate axis; that is, a point is drawn only at the third position. When the target digital waveform value set does not contain a high level value, the target pixel value is drawn only at the fourth position corresponding to the low level on the target pixel and signal value coordinate axis; that is, a point is drawn only at the fourth position. This completes the drawing of the target digital waveform portion when the target pixel is the first pixel on the time axis.

[0098] The technical solution of this invention can, in response to a request to display a target digital waveform in a target display coordinate system within a GUI, obtain a time window matching the target digital waveform and a pixel window matching the time axis in the target display coordinate system. Based on the waveform start and end times in the time window and the signal sampling interval corresponding to the target digital waveform, a set of waveform time points matching the time window is determined, and the total number of time points contained in the waveform time point set is obtained. Based on the start and end pixel sizes of the pixel window on the time axis, the total number of pixels in the time coordinate system is calculated. If the total number of time points is greater than the total number of pixels, it is determined that the target digital waveform cannot be completely drawn in the target display coordinate system. The digital waveform values ​​corresponding to each waveform time point in the waveform time point set are obtained by traversing the set, and the set of digital waveform values ​​corresponding to each pixel on the time axis is calculated. The method involves obtaining the target digital waveform value set corresponding to the target pixel on the time axis, and acquiring the previous drawing result for the previous pixel. Based on the inclusion of high and low level values ​​in the target digital waveform value set and the previous drawing result, matching point drawing and / or line drawing operations are performed on the target pixel within the target display coordinate system in the GUI, thereby drawing the target digital waveform within the target display coordinate system in the GUI. This technical solution completes the drawing of the target digital waveform portion by considering the level values ​​included in the target digital waveform value set corresponding to the target pixel and the previous drawing result of adjacent pixels. It implements a specific method to avoid repeated drawing at the same pixel during digital waveform scaling and drawing, improving the efficiency of digital waveform sampling and drawing, and solving the problem of stuttering caused by repeated drawing.

[0100] Figure 8 This is a schematic diagram of the structure of a GUI display device for a digital waveform provided in Embodiment 3 of the present invention. Figure 8 As shown, the device includes: a waveform drawing resource acquisition module 810, a digital waveform value set acquisition module 820, and a digital waveform drawing module 830.

[0101] The waveform drawing resource acquisition module 810 is used to acquire a time window that matches the target digital waveform and a pixel window that matches the time axis in the target display coordinate system in response to a request to display the target digital waveform in the target display coordinate system.

[0102] The digital waveform value set acquisition module 820 is used to calculate the digital waveform value set corresponding to each pixel point in the time coordinate axis when it is determined from the time window and pixel window that the target digital waveform cannot be completely drawn in the target display coordinate system.

[0103] The digital waveform drawing module 830 is used to draw the target digital waveform in the target display coordinate system in the GUI based on the set of digital waveform values ​​corresponding to each pixel point in the time coordinate axis.

[0104] The technical solution of this invention can, in response to a request to display a target digital waveform in a target display coordinate system within a GUI, acquire a time window matching the target digital waveform and a pixel window matching the time axis in the target display coordinate system. When it is determined, based on the time window and pixel window, that the target digital waveform cannot be completely drawn in the target display coordinate system, a set of digital waveform values ​​corresponding to each pixel point on the time axis is calculated. Based on the set of digital waveform values ​​corresponding to each pixel point on the time axis, the target digital waveform is drawn in the target display coordinate system within the GUI. This technical solution, by sampling and drawing the target digital waveform values ​​according to the target display coordinate system, significantly improves the efficiency of digital waveform scaling operations and enhances the convenience of debugging digital waveforms in chip simulation.

[0105] Optionally, the digital waveform value set acquisition module 820 can be specifically used to: determine the waveform time point set matching the time window based on the waveform start and end times in the time window and the signal sampling interval corresponding to the target digital waveform, and obtain the total number of time points contained in the waveform time point set. Here, one waveform time point corresponds to one digital waveform value in the target digital waveform, and the digital waveform value includes high-level and low-level values. The total number of pixels contained in the time coordinate system is calculated based on the start and end pixel sizes of the pixel window on the time coordinate axis. If the total number of time points is greater than the total number of pixels, it is determined that the target digital waveform cannot be completely drawn within the target display coordinate system.

[0106] Optionally, the digital waveform value set acquisition module 820 can also be specifically used to: sequentially acquire a current waveform time point from the waveform time point set; based on the current waveform time point, the starting pixel size and ending pixel size of the pixel window, call a pre-built coordinate transformation formula to calculate the current pixel point mapped to the time coordinate axis in the pixel window; add the digital waveform value at the current waveform time point to the digital waveform value set corresponding to the current pixel point; return to execute the operation of sequentially acquiring a current waveform time point from the waveform time point set until all waveform time points in the waveform time point set have been processed to obtain the digital waveform value set corresponding to each pixel point in the time coordinate axis.

[0107] Optionally, the digital waveform plotting module 830 may specifically include:

[0108] The reference information acquisition unit is used to acquire the set of target digital waveform values ​​corresponding to the target pixel in the time coordinate axis, and to acquire the previous drawing result executed for the previous pixel of the target pixel.

[0109] The previous drawing result includes the first drawing point value at a first position corresponding to the first height in the signal value coordinate axis of the previous pixel and the target display coordinate system, or the second drawing point value at a second position corresponding to the second height in the signal value coordinate axis of the previous pixel; the first height corresponds to the high level value, and the second height corresponds to the low level value.

[0110] The actual drawing unit is used to perform matching point drawing and / or line drawing operations on the target pixel points in the target display coordinate system in the GUI, based on the inclusion of high and low level values ​​in the target digital waveform value set and the previous drawing result.

[0111] Optionally, the actual drawing unit can be specifically used to: if the target digital waveform value set contains a high-level value, and the previous drawing result is a first drawing point value, then draw the target drawing point value only at the third position corresponding to the first height in the coordinate axis of the target pixel and the signal value. If the target digital waveform value set contains a high-level value, and the previous drawing result is a second drawing point value, then after drawing the target drawing point value at the third position, draw the connection between the second drawing point value and the target drawing point value.

[0112] Optionally, the actual drawing unit can also be specifically used to: if the target digital waveform value set does not contain a high-level value, and the previous drawing result is a first drawing point value, then after drawing the target drawing point value at the fourth position corresponding to the second height in the coordinate axis of the target pixel point and the signal value, draw the line connecting the first drawing point value and the target drawing point value. If the target digital waveform value set does not contain a high-level value, and the previous drawing result is a second drawing point value, then only draw the target drawing point value at the fourth position.

[0113] Optionally, the actual drawing unit can also be specifically used to: if the target pixel is the first pixel on the time axis, detect whether the target digital waveform value set contains a high-level value. If so, draw the target pixel value only at the third position corresponding to the first height on the target pixel and signal value coordinate axis. Otherwise, draw the target pixel value only at the fourth position corresponding to the second height on the target pixel and signal value coordinate axis.

[0114] The digital waveform GUI display device provided in the embodiments of the present invention can execute the digital waveform GUI display method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of executing the method.
