Embodiment

[0034] Such as figure 1 As shown, the embodiment of the present invention provides a method for assigning attributes to tabs in batches in PCB design, and the method includes:

[0035] Step 1: Call the skill program to obtain the marquee area. The specific implementation process is as follows: first, after calling the skill program, prompt the user to select the area, and wait for the user's operation; then, after the user selects the area, obtain the coordinates of the lower left corner and the upper right corner of the area selected by the user, thereby reading the selected area.

[0036] Step 2: Set the object type of the tab and grab all the tabs in the marquee area. The specific method is: set the filter to select the state of "shape", where shape is the object type of the tab.

[0037] The purpose of setting the filter is to filter objects when grabbing. Since the filter is set to the selected "shape" state, all objects in the grabbing area can accurately grab the requi...

Abstract

The present invention provides a method and device for assigning attributes to tabs in batches in PCB design. The method includes: step 1: call the skill program to obtain the frame selection area; step 2: set the object type of the tab and grab the frame Select all the tabs in the area; step 3: set the object type of the high-speed line within the area of ​​the tab, and capture the attributes of the high-speed line; step 4: assign the attributes of the high-speed line to the tab according to the correspondence between the high-speed line and the tab. The device includes: a selection module, used to prompt and read the area selected by the user; a first grabbing module, used to grab all the tabs in the framed area; a second grabbing module, used to grab The attribute of the high-speed line within the area of ​​the tab; the assignment module is used to assign the attribute of the high-speed line to the tab according to the corresponding relationship between the tab and the high-speed line. The invention makes up for the shortcomings of the prior art, such as complex process, low efficiency and easy omissions.

Description

technical field [0001] The invention relates to the field of PCB board design, and more specifically, relates to a method and a device for assigning attributes to tabs in batches in PCB design. Background technique [0002] In PCB design, in order to ensure the impedance continuity and signal quality of the high-speed line, it is necessary to add a tab to the high-speed line. The tab is a single independent small-area shape. After assigning attributes, the two belong to the same net. [0003] In the existing technical solutions, technicians manually assign attributes to individual tabs. The main disadvantages are: 1) the number of tabs is large, and the single operation process is complicated and inefficient; 2) it is easy to omit, which affects the signal quality. Contents of the invention [0004] In view of the above disadvantages, the present invention proposes a method for checking that the width of traces exceeds the width of pads in PCB design, which makes up for t...
