Description

Waveform display method, computer device, and storage medium

Technical Field

The present application relates to the field of electronic technology, 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. While debugging of logic system designs typically involves debugging of simulation waveforms. For example, for a logic system design, a waveform diagram of a signal within a certain time can be obtained through a simulation tool, and debugging on the logic system design can be realized through debugging the waveform displayed on a waveform viewer.

In general, the waveform obtained by the simulation tool is often the waveform of the chip in the whole operation time period, and when the operation time period is longer, the display interface of the waveform viewer cannot completely and clearly display the whole waveform. As shown in fig. 1, it is now possible to control the display of waveforms for different time periods by moving the scroll bar 02 under the waveform viewer 01. In the process of moving the scroll bar 02, the distance of each movement of the waveform is determined by the dimension of the scroll bar 02, and as shown in fig. 1, the dimension of the scroll bar 02 is represented by the length of the scroll bar 02. If the scroll bar 02 is oversized, the waveform has moved for a large time interval even if the scroll bar 02 has moved only a small distance; if the scroll bar 02 is too small in scale, the waveform will only move for a small time interval even if the scroll bar 02 moves a large distance. The scale of the scroll bar 02 is a scale of the scroll bar 02, and the scale is as shown by scale 04 in fig. 1.

However, the debugging of the simulation waveform may run through the whole chip operation cycle, and it is difficult to accurately locate the waveform corresponding to the target time interval by moving the scroll bar at present, thereby resulting in low simulation efficiency.

Therefore, in the waveform debugging process, it is highly desirable to find a method that can quickly adjust the scale of the scroll bar so as to accurately locate and display the waveform diagram requiring the debugging time period.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.

It is to be noted that, unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which this application belongs. As used in this application, the terms "first," "second," and the like 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 the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

As described above, it is difficult to accurately locate a waveform corresponding to a target time interval by moving a scroll bar during a waveform simulation process of a logic system design (e.g., a chip design). The waveform obtained by the simulation tool is often long in running time, and a user needs to move the waveform diagram to find the waveform of the time period needing debugging. The user moves to the time axis for the corresponding time by moving a scroll bar (e.g., scroll bar 02 shown in fig. 1) under the waveform viewer, which displays the waveform at the time position of the scroll bar. In the moving process, the distance of each movement of the waveform is determined by a scale of the scroll bar, and the length of the scale corresponds to the length of the scroll bar on the time axis. If the scale is too large, the waveform has moved for a large time interval even if the scrollbar has moved only a small distance; if the scale is too small, the scroll bar moves a lot, and the waveform moves for a very 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 a waveform display region from the waveform data. The waveform data may be waveform data of the correlation signal obtained by simulating the logic system design. The waveform data may include a plurality of time periods, e.g., 0 to 2,000, 2,000 to 4,000, 4,000 to 6,000, etc. The time unit of the waveform data may be picoseconds, nanoseconds, milliseconds, etc., and may be 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 as shown in fig. 3, a time axis 41, and a scroll bar 42 movable along the time axis 41. 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, and the space occupation is reduced.

The computer device 100 may receive user operating instructions that may include activating modification of the scrollbar 42, and modifying the scope of the scrollbar 42.

As shown in fig. 3, when the user needs to adjust the scale of the scroll bar, the user can click on an end point of the scroll bar 42 located on the time axis 41 in fig. 3. For example, the left end point or the right end point of the scroll bar 42 may be clicked by a cursor of a mouse, or the left end point or the right end point of the scroll bar 42 may be clicked by a touch based on a touch screen, so as to initiate an activation instruction for modifying the scroll bar 42. The computer device 100 may then receive a cursor click on one end point (left end point or right end point) of the scrollbar 42, i.e., receive an activation instruction to modify the scrollbar 42.

In some embodiments, when the user clicks one end point of the scroll bar 42 through the cursor, the modification of the scroll bar 42 is activated, and if the end point of the scroll bar 42 dragged by the user continues to move at this time, the original dimension of the scroll bar 42 may be changed, i.e., the range of the scroll bar 42 is modified. And the computer device 100 may determine to modify the extent of the scrollbar 42 based on the corresponding direction and distance of movement of the cursor. For example, when the movement direction is moving the end point to the left of the drag scroll bar 42 to the left, then the computer device 100 may increase the scale of the scroll bar based on the specific movement distance to get a new scroll bar; when the movement direction is the movement of the end point to the left of the dragged scroll bar 42 to the right, the computer device 100 may decrease the scale of the scroll bar based on the specific movement distance to obtain a new scroll bar; when the movement direction is dragging the endpoint on the right side of the scroll bar 42 to the right, then the computer device 100 may increase the scale of the scroll bar based on the specific movement distance to obtain a new scroll bar; when the direction of movement is to drag the endpoint to the right of the scroll bar 42 to the left, then the computer device 100 may decrease the scale of the scroll bar based on the particular distance of movement to obtain a new scroll bar. For another example, when the movement direction is dragging the endpoint to the left of the scroll bar 42 to the right, then the computer device 100 may regenerate the scroll bar based on the particular movement distance, and the dimensions of the newly generated scroll bar may coincide with the movement distance. 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 dimension of the scroll bar 52, any point on the time axis 51 in fig. 4 may also be clicked, so as to initiate an activation instruction for modifying the scroll bar 52. The computer device 100 may then receive the activation command and determine that any point on the time axis 51 is the first point based on the click of that point, i.e., the first end point of the scaled scrollbar 53.

To modify the extent of the scroll bar, computer device 100 may determine a direction of movement and a distance of movement of the cursor, and determine that the cursor rests at a second point on the time axis based on the direction of movement and the distance of movement. The second point may be a second end point of the scaled scroll bar 53, and a connection line formed by the two end points is the scaled scroll bar 53. The moving direction and the moving distance of the cursor may refer to a moving direction and a 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 the modification of the scrollbar, and determine the first point as the first endpoint of the resized scrollbar 53. If the user drags the cursor to move from the first point continuously, such as to move to the left or to the 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, and the computer device 100 may determine the second point as a second endpoint of the scaled scroll bar 53. Thus, the computer device 100 may generate the scaled scrollbar 53 based on the first endpoint and the second endpoint, both endpoints of the scrollbar 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 needs to adjust the size of the scroll bar, the cursor may be moved to the corresponding scroll bar by operating the mouse or the touch screen, and the computer device 100 may recognize the movement of the cursor to the scroll bar, thereby activating the modification of the scroll bar. If the user controls the scroll wheel of the mouse by operating the mouse at this time, the computer apparatus 100 may modify the range of the scroll bar based on the scroll wheel of the mouse. For example, if the scroll wheel rolls upwards, the original scroll bar is expanded; if the roller rolls downwards, the original scroll bar is shortened, and therefore expansion or shortening of the scroll bar is achieved.

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 needs to adjust the dimensions of the scroll bar 62, then any point in the waveform diagram 60 of fig. 5 may be clicked, thereby initiating an activation instruction that modifies the scroll bar 62. The computer device 100 may then receive the activation instruction and determine that any point on the waveform diagram 60 is a third point based on a click of that point. By associating the third point on the time axis 61, the point on the time axis 61 can be determined as the first end point of the scaled scroll bar 63.

If the user drags the third point to move continuously (for example, move to the left or move to the right) on the waveform diagram 60 and stops moving after moving a certain distance, the cursor stays at the fourth point on the waveform diagram 60 where the movement is stopped. Similarly, by associating the fourth point on time axis 61, the point on time axis 61 to which the fourth point corresponds may be determined to be the second end point of scaled scrollbar 63. Accordingly, the computer device 100 can generate the scaled scroll bar 63 based on the first endpoint and the second endpoint, thereby enabling flexible modification of the scroll bar scale.

In some embodiments, the computer device 100 may also determine the display range of the waveform map according to the range of the modified scroll bar. As shown in fig. 5, the display range of the waveform map may be shown by a scale 64 above the waveform display area. The scroll bar 62 before modification ranges from 250,000,000 to 550,000,000, and the corresponding dimension, i.e., the distance between the two end points of the scroll bar 62, is 300,000,000 (i.e., 550,000,000-250,000,000). The displayed range of the waveform diagram 60 now corresponds to the dimensions of the scroll bar 62. If the scroll bar 62 is moved to a position on the time axis 61, the display range of the waveform diagram 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 are located at 300,000,000 and 600,000,000 on the time axis 61 after the movement, respectively, the waveform diagram 60 may be displayed in a range of 300,000,000 to 600,000,000, and the scale of the display (600,000,000-300,000 =300,000,000) is consistent with the scale of the display before the movement (550,000,000-250,000,000 =300,000,000). That is, by moving the position of the scroll bar 62 on the time axis 61, the waveform diagram at different positions on the time axis 61 can be displayed with the range of the scroll bar 62 as a scale.

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 extent of scroll bar 62 to generate a new scroll bar 63. For example, the new scrollbar 63 may range from 380,000,000 to 500,000,000. At this time, the scale of the scroll bar is changed from the original scale of 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 is also changed. As shown in fig. 6, the display range of the waveform diagram 70 coincides with the range of the modified scroll bar 63. That is, the computer apparatus 100 can display the 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 illustrating 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. The waveform data may be obtained by a simulation tool simulating a logic system design. The waveform data may include a plurality of time periods (e.g., 0 to 2,000, 2,000 to 4,000, 4,000 to 6,000, etc.). The time unit of the waveform data may be picoseconds, nanoseconds, milliseconds, etc., and may be 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 coincide with the time axis 41, so that the space occupation of the waveform display area can be reduced.

At step 704, the computer device 100 may receive an operating instruction. The operating instructions may be from a user and may include activating a modification of the scrollbar and modifying a scope of the scrollbar.

In some embodiments, activating the modification of the scrollbar further comprises: the computer device 100 may receive a cursor click on an end point of the scroll bar (e.g., the left or right end point of the scroll bar 42 shown in fig. 3). Modifying the range of the scrollbar further comprises: computer device 100 may determine the direction of movement (e.g., left movement or right movement) and the distance of movement that the end point of the scrollbar follows the cursor.

In some embodiments, activating the modification of the scrollbar (e.g., scrollbar 52 shown in FIG. 4) further comprises: computer device 100 may receive a cursor click on a first point of the timeline (e.g., timeline 51 shown in fig. 4). Modifying the range of the scrollbar further comprises: the computer device 100 may determine a moving direction and a moving distance of the cursor, and determine that the cursor stays at a second point on the time axis according to the moving direction and the moving distance. Two end points of the modified scroll bar (e.g., scroll bar 53 shown in fig. 4) correspond to the first point and the second point.

In some embodiments, activating the modification of the scrollbar further comprises: computer device 100 may recognize that the cursor is moving over the scrollbar. Modifying the range of the scrollbar further comprises: the computer device 100 may determine the scroll of the scroll wheel and expand or contract the scrollbar based on the scroll of the scroll wheel.

In some embodiments, activating the modification of the scrollbar further comprises: the computer device 100 may receive a cursor click on a third point of the waveform map (e.g., the waveform map 60 shown in fig. 5). Modifying the scope of the scrollbar (e.g., scrollbar 62 shown in FIG. 5) further comprises: the computer device 100 may determine a moving direction and a moving distance of the cursor, and determine a fourth point at which the cursor stays on the waveform diagram according to the moving direction and the moving distance. Computer device 100 may map the third point to a time axis (e.g., time axis 61 shown in fig. 5), and determine a first end point of a modified scrollbar (e.g., scrollbar 63 shown in fig. 5); similarly, the computer device 100 may correspond the fourth point to a time axis (e.g., time axis 61 shown in fig. 5) and determine a second end point of the modified scrollbar (e.g., scrollbar 63 shown in fig. 5).

In step 706, the computer device 100 may display the modified scroll bar according to the operation instruction.

In some embodiments, the computer device 100 may generate the modified scrollbar (e.g., scrollbar 53 shown in FIG. 4) with two endpoints corresponding to the first point and the second point (e.g., two endpoints of scrollbar 53 shown in FIG. 4).

In some embodiments, computer device 100 may generate a modified scroll bar (e.g., scroll bar 63 shown in FIG. 5) from the third and fourth points. As depicted in step 704, computer device 100 may map the third point to a time axis (e.g., time axis 61 shown in FIG. 5) to determine a first end point of the modified scrollbar; similarly, the computer device 100 may map the fourth point to the time axis to determine a second end point of the modified scrollbar.

In some embodiments, the computer device 100 may also determine a display range (e.g., 380,000,000 to 500,000,000) of the waveform diagram (e.g., the waveform diagram 70 shown in fig. 6) based on the range of the modified scrollbar (e.g., the scrollbar 63 shown in fig. 6).

In the waveform display method, the computer device 100 may generate the waveform display area according to the waveform data, receive the operation instruction, and display the modified scroll bar according to the operation instruction, so as to simply and conveniently adjust the scale of the scroll bar, and accurately position the oscillogram in the time period required to be debugged, thereby improving the simulation efficiency.
