s104: and according to the coordinate values of the central points of the two through holes, respectively extending the lengths of the radiuses of the two circular areas from the central points of the two through holes up and down, drawing a rectangular area between the two through holes by taking the extended line segment as the side length, and combining the rectangular area and the two circular areas into an oval limiting area.
In the Layout (Layout) design, a program is written to draw a signal-constrained region (Route-keepout) at a full-board differential line via, and a Layout engineer can define a drawing level for drawing the signal-constrained region according to a result simulated by a signal simulation engineer and the size of the differential line via.
In some embodiments, the method searches for signals NET with Diff Pair (Differential Pair) parameters set in the board, while signals with non-Differential line properties are not searched for Differential lines (because non-Differential signals do not set Diff Pair parameters). This action is used to determine whether the differential line signal should be selected to achieve one-time selection to the whole board. For example, the signals NET with all Diff Pair parameters set within a board are listed via the program code Search ("Diff Pair") $ NET.

And then, drawing a signal limiting area according to the magnitude of the externally expanded value input by a layout engineer and by taking the center of the differential line via hole as a reference. The program selects the differential line via hole and captures the center coordinate of the via hole as a reference to draw a signal limiting area. As shown in fig. 2, the diameter of the via is 20mil, and two circles are drawn according to the magnitude of the externally-expanded value inputted by externally expanding the selected signal confinement region level based on the centers of the two vias, wherein fig. 2 takes 5mil as an example. The via has a diameter of 20mil, and a rectangular area is drawn based on the center of the two vias and according to the magnitude of the outward expansion value inputted by the outward expansion of the selected signal confinement region layer, as shown in fig. 3, which takes the outward expansion of 5mil as an example. Finally, the two plotted graphs are combined into an ellipse which conforms to the results of the SI simulation, as shown in FIG. 4.
In some embodiments, the method further comprises: in response to receiving an indication to redraw, the rendered region is de-keyed to redraw. The method of the present invention also provides a function of deleting the drawn signal-bounding region (Route-keeper) by one key. If the differential line via hole is changed, the limiting area needs to be redrawn, and the function of deleting the drawn signal limiting area by one key is provided.
