Description
Technical Field
The present application relates to the field of electronics, and in particular, to a waveform display method, a computer device, a storage medium, and a computer program product.
Background
With the development of electronic technology, logic system designs (e.g., chip designs) have been widely used. Whereas debugging of logic system designs typically involves debugging of the emulated waveforms. For example, for a logic system design, a waveform diagram of a signal over a period of time may be obtained by a simulation tool, while debugging of the logic system design may be accomplished by debugging waveforms displayed on a waveform viewer.
In general, the waveform diagram obtained by the simulation tool is often the waveform of the chip in the whole operation period, and when the operation period is long, the display interface of the waveform viewer cannot completely and clearly display the whole waveform diagram. As shown in fig. 1, the display of waveforms for different time periods can now be controlled by moving the scroll bar 02 under the waveform viewer 01. In moving the scroll bar 02, the distance that the waveform moves each time is determined by the scale of the scroll bar 02, as shown in fig. 1, the scale of the scroll bar 02 is embodied as the length of the scroll bar 02. If the dimensions of the scroll bar 02 are too large, the waveform has moved a significant time interval even though the scroll bar 02 has moved only a small distance; whereas if the dimensions of the scroll bar 02 are too small, the waveform is only shifted for a small time interval even if the scroll bar 02 is shifted a large distance. The scale of the scroll bar 02 is the scale of the scroll bar 02, and the scale size of the scale is shown as a scale 04 in fig. 1.
However, since the debugging of the simulation waveform runs through the whole chip operation period, it is difficult to accurately position the waveform corresponding to the target time interval by moving the scroll bar at present, so that the simulation efficiency is low.
Therefore, in the process of waveform debugging, it is needed to find a method that can quickly adjust the scale of the scroll bar so as to accurately locate and display the waveform diagram of the time period required to be debugged.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
It is to be noted that unless otherwise defined, technical or scientific terms used herein should be taken in a general sense as understood by one of ordinary skill in the art to which this application belongs. The terms "first," "second," and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
As described above, since it is difficult to accurately locate a waveform corresponding to a target time zone by moving a scroll bar during waveform simulation of a logic system design (e.g., a chip design). The waveforms obtained by the simulation tool tend to be run for a relatively long time, and the user needs to move the waveform map to find the waveform for that time period that needs to be debugged. The user moves to the corresponding time on the time axis by moving the scroll bar (e.g., scroll bar 02 shown in fig. 1) below the waveform viewer, on which the waveform of the time position where the scroll bar is located is displayed. In the moving process, the distance of each movement of the waveform is determined by the scale of the rolling bar, and the length of the scale corresponds to the length of the rolling bar on the time axis. If the scale is too large, the waveform has moved a significant time interval even though the scrollbar has moved only a small distance; if the scale is too small, the scroll bar moves much and the waveform moves only a small time interval. Meanwhile, as shown in fig. 1, the time axis 03 and the scroll bar 02 are separated, and occupy a relatively large space.
Based on this, the present application provides a waveform display method, a computer device, a storage medium, and a computer program product to solve the above-described problems.

Fig. 3 is a schematic diagram of a waveform display according to an embodiment of the present application.
In some embodiments, the computer device 100 may generate the waveform display area from waveform data. The waveform data may be waveform data of a correlation signal obtained after simulation of the logic system design. The waveform data may include a plurality of time periods, for example, 0 to 2,000, 2,000 to 4,000, 4,000 to 6,000, and the like. The time unit of the waveform data may be picoseconds, nanoseconds, milliseconds, etc., and may be specifically determined according to parameters of an actual logic system design. Corresponding to the waveform data, the waveform display area may include a waveform diagram 40, a time axis 41, and a scroll bar 42 movable along the time axis 41 as shown in fig. 3. The time interval of the time axis 41 may correspond to a period of the waveform data. Since the scroll bar 42 is located on the time axis 41, the scroll bar 42 and the time axis 41 share the same space at this time, and space occupation is reduced.
The computer device 100 may receive user operational instructions that may include modifications that activate the scrollbar 42, as well as modifying the scope of the scrollbar 42.
As shown in fig. 3, when the user needs to adjust the dimensions of the scroll bar, the user may click on one end point of the scroll bar 42 located on the time axis 41 in fig. 3. For example, the left or right end point of the scroll bar 42 may be clicked by a cursor of a mouse, or an activation instruction for modifying the scroll bar 42 may be initiated by touching the left or right end point of the scroll bar 42 based on a touch screen. The computer device 100 may then receive a cursor click on one of the endpoints (left or right endpoint) of the scrollbar 42, i.e., receive an activation instruction to modify the scrollbar 42.
In some embodiments, when the user clicks one of the endpoints of the scrollbar 42 via the cursor, then the modification to the scrollbar 42 is activated, and if the user drags the endpoint of the scrollbar 42 to continue moving at this point, then the original dimensions of the scrollbar 42 may be changed, i.e., the range of the scrollbar 42 is modified. And the computer device 100 may determine to modify the extent of the scrollbar 42 based on the direction and distance of movement corresponding to the cursor. For example, when the direction of movement is to drag the endpoint to the left of the scrollbar 42, then the computer device 100 may increase the scale of the scrollbar based on the particular distance of movement to obtain a new scrollbar; when the direction of movement is to drag the left end of the scrollbar 42 to move to the right, then the computer device 100 may decrease the scale of the scrollbar based on the particular distance of movement to obtain a new scrollbar; when the direction of movement is to drag the right end of the scrollbar 42 to move to the right, the computer device 100 may increase the scale of the scrollbar based on the specific distance of movement to obtain a new scrollbar; when the direction of movement is to drag the right end of the scrollbar 42 to the left, then the computer device 100 may decrease the dimensions of the scrollbar based on the particular distance of movement to obtain a new scrollbar. For another example, when the direction of movement is to drag the end point to the left of the scrollbar 42 to the right, then the computer device 100 may regenerate the scrollbar based on the particular distance of movement, and the dimensions of the newly generated scrollbar may be consistent with the distance of movement. In this way, the computer device 100 may enable flexible modification of the scroll bar dimensions.
Fig. 4 is a schematic diagram of another waveform display according to an embodiment of the present application.
In some embodiments, as shown in FIG. 5, when the user needs to adjust the dimensions of the scrollbar 52, the user may also click on any point on the timeline 51 of FIG. 4, thereby initiating an activation instruction that modifies the scrollbar 52. The computer device 100 may then receive the activation instruction and determine, based on clicking on any point on the timeline 51, that point as the first point, i.e., the first endpoint of the resized scroll bar 53.
To modify the range of the scroll bar, the computer device 100 may determine the direction and distance of movement of the cursor, from which the second point on the time axis the cursor resides. The second point may be a second end point of the scrollbar 53 after the scaling, and the connection line formed by the two end points is the scrollbar 53 after the scaling. The moving direction and moving distance of the cursor may refer to the moving direction and moving distance of the cursor with respect to the first point. For example, the user may click on the timeline 51 with a cursor to determine a first point, activate a modification to the scrollbar, and determine the first point as the first endpoint of the resized scrollbar 53. If the user drags the cursor to continue moving from the first point, such as to the left or right, and stops moving after moving a certain distance, the cursor stays at a second point on the time axis where the movement is stopped, the computer device 100 may determine the second point as the second end point of the scrollbar 53 after the scaling. Thus, the computer device 100 may generate the resized scroll bar 53 based on the first endpoint and the second endpoint, and both endpoints of the scroll bar 53 may correspond to the first point and the second point. In this way, the computer device 100 may enable flexible modification of the scroll bar dimensions.
In some embodiments, when the user desires to adjust the dimensions of the scroll bar, the computer device 100 may also activate a modification to the scroll bar by manipulating a mouse or touch screen to move a cursor over the corresponding scroll bar. If the user controls the scroll wheel scrolling of the mouse by operating the mouse at this time, the computer device 100 may modify the range of the scroll bar based on the scrolling of the mouse scroll wheel. For example, if the roller rolls upwards, the original scroll bar is expanded; if the roller rolls downwards, the original rolling bar is shortened, so that the rolling bar is expanded or shortened.
Fig. 5 is a schematic diagram of yet another waveform display according to an embodiment of the present application.
In some embodiments, when the user desires to adjust the dimensions of the scroll bar 62, then any point in the waveform diagram 60 of FIG. 5 may be clicked on to initiate an activation instruction to modify the scroll bar 62. The computer device 100 may then receive the activation instruction and determine that any point on the waveform 60 is the third point based on clicking on that point. By associating this third point with the time axis 61, the point that will correspond to the time axis 61 can be determined as the first end point of the resized scroll bar 63.
If the user drags the third point to continue moving (e.g., left or right) on the waveform 60 at this time and stops moving after moving a certain distance, the cursor stays at the fourth point on the waveform 60 where the movement is stopped. Similarly, by corresponding the fourth point to the time axis 61, the point on the time axis 61 corresponding to the fourth point can be determined as the second end point of the resized scroll bar 63. Thus, the computer device 100 may generate the resized scrollbar 63 based on the first endpoint and the second endpoint, thereby enabling flexible modification of the scrollbar dimensions.
In some embodiments, the computer device 100 may also determine the display range of the waveform map from the modified scroll bar range. As shown in fig. 5, the display range of the waveform diagram may be shown by a scale 64 above the waveform display area. The pre-modification scrollbar 62 ranges from 250,000,000 to 550,000,000, then the corresponding dimension is the distance between the two endpoints of the scrollbar 62 of 300,000,000 (i.e., 550,000,000-250,000,000). The displayed range of the waveform 60 corresponds to the scale of the scroll bar 62. If the position of the scroll bar 62 on the time axis 61 is moved, the display range of the waveform chart 60 matches the new position of the scroll bar 62 on the time axis 61, but the scale of the corresponding display remains unchanged. For example, by moving the position of the scroll bar 62 on the time axis 61, if the two end points after the movement are respectively located at 300,000,000 and 600,000,000 on the time axis 61, the display range corresponding to the waveform diagram 60 may be 300,000,000 to 600,000,000, and the scale (600,000,000-300,000,000 =300,000,000) displayed corresponds to the scale (550,000,000-250,000,000 =300,000,000) displayed before the movement. That is, by moving the position of the scroll bar 62 on the time axis 61, a waveform chart of different positions on the time axis 61 on the scale of the range of the scroll bar 62 can be displayed.
Fig. 6 is a schematic diagram of yet another waveform display according to an embodiment of the present application.
In some embodiments, the user may modify the scope of the scrollbar 62 to generate a new scrollbar 63. For example, the new scroll bar 63 may range from 380,000,000 to 500,000,000. At this point, the dimensions of the scrollbar change from the original dimensions 300,000,000 (i.e., 550,000,000-250,000,000) to 120,000,000 (i.e., 500,000,000-380,000,000). The display range of the waveform diagram also changes at this time. As shown in fig. 6, the displayed range of the waveform diagram 70 coincides with the range of the modified scroll bar 63. That is, the computer device 100 can display a waveform map corresponding to the range of the scroll bar by modifying the scale of the scroll bar, thereby making it easier to display the waveform map at the target time.
Fig. 7 is a flowchart of a waveform display method 700 according to an embodiment of the present application. The method 700 may be run on a computer device 100 as shown in fig. 2. Referring to fig. 7, the method 700 may include the following steps.
At step 702, the computer device 100 may generate a waveform display area from the waveform data. Waveform data may be obtained by simulating a logic system design with a simulation tool. The waveform data may include a plurality of time periods (e.g., 0-2,000, 2,000-4,000, 4,000-6,000, etc.). The time unit of the waveform data may be picoseconds, nanoseconds, milliseconds, etc., and may be specifically determined according to parameters of an actual logic system design. The waveform display area may include a waveform diagram (e.g., waveform diagram 40 shown in fig. 3), a time axis (e.g., time axis 41 shown in fig. 3), and a scroll bar (e.g., scroll bar 42 shown in fig. 3) movable along the time axis. The scroll bar 42 may be located in the time axis 41 and coincides with the time axis 41, so that space occupation of the waveform display area may be reduced.
At step 704, the computer device 100 may receive an operation instruction. The operating instructions may be from a user and may include a modification to activate the scrollbar and a modification of the scope of the scrollbar.
In some embodiments, activating the modification of the scrollbar further includes: the computer device 100 may receive a cursor click on an end point of the scrollbar (e.g., the left end point or the right end point of the scrollbar 42 shown in fig. 3). Modifying the range of the scrollbar further includes: the computer device 100 may determine the direction of movement (e.g., left or right movement) and distance of movement that the end point of the scroll bar follows the cursor.
In some embodiments, the modification to activate the scrollbar (e.g., scrollbar 52 shown in FIG. 4) further includes: the computer device 100 may receive a cursor click on a first point of the timeline (e.g., the timeline 51 shown in fig. 4). Modifying the range of the scrollbar further includes: the computer device 100 may determine a direction of movement and a distance of movement of the cursor, and determine a second point on the timeline at which the cursor resides based on the direction of movement and the distance of movement. Two end points of the modified scrollbar (e.g., scrollbar 53 shown in fig. 4) correspond to the first point and the second point.
In some embodiments, activating the modification of the scrollbar further includes: the computer device 100 may recognize that the cursor is moving onto the scroll bar. Modifying the range of the scrollbar further includes: the computer device 100 may determine the scroll of the wheel, expanding or contracting the scrollbar according to the scroll of the wheel.
In some embodiments, activating the modification of the scrollbar further includes: computer device 100 may receive a cursor click on a third point of the waveform diagram (e.g., waveform diagram 60 shown in fig. 5). Modifying the extent of the scrollbar (e.g., scrollbar 62 shown in FIG. 5) further includes: the computer device 100 may determine a direction of movement and a distance of movement of the cursor, and determine a fourth point on the waveform diagram at which the cursor rests based on the direction of movement and the distance of movement. The computer device 100 may correspond the third point to a time axis (e.g., time axis 61 shown in fig. 5) to determine a first endpoint of the modified scrollbar (e.g., scrollbar 63 shown in fig. 5); similarly, the computer device 100 may correspond this fourth point to the timeline (e.g., the timeline 61 shown in FIG. 5) to determine a second endpoint of the modified scrollbar (e.g., the scrollbar 63 shown in FIG. 5).
In step 706, the computer device 100 may display a modified scroll bar according to the operation instruction.
In some embodiments, the computer device 100 may generate the modified scroll bar (e.g., scroll bar 53 shown in fig. 4) with two endpoints of the modified scroll bar corresponding to a first point and a second point (e.g., two endpoints of scroll bar 53 shown in fig. 4).
In some embodiments, computer device 100 may generate a modified scrollbar (e.g., scrollbar 63 shown in fig. 5) from the third point and the fourth point. As described in step 704, the computer device 100 may correspond the third point to a time axis (e.g., time axis 61 shown in fig. 5) to determine a first endpoint of the modified scrollbar; similarly, the computer device 100 may correspond the fourth point to the timeline to determine a second endpoint of the modified scrollbar.
In some embodiments, the computer device 100 may also determine the display range (e.g., 380,000,000 to 500,000,000) of the waveform map (e.g., waveform map 70 shown in fig. 6) from the range of the modified scroll bar (e.g., scroll bar 63 shown in fig. 6).
In the above waveform display method, the computer device 100 may generate the waveform display area according to the waveform data, and receive the operation command to display the modified scroll bar according to the operation command, so as to simply and conveniently implement adjustment of the scale of the scroll bar, so as to accurately locate the waveform diagram of the time period required to be debugged, and further improve the simulation efficiency.
