Layout design method with high anti-interference capability

The invention relates to a layout design method with high anti-interference capability. The layout design method comprises the following steps: step 1, drawing a linear signal line; 2, sawtooth protrusions are drawn on the two sides of the signal line, each sawtooth protrusion is in a regular trapezoid shape, the bottom of each sawtooth protrusion in the regular trapezoid shape is large and connected with the signal line, and the top of each sawtooth protrusion in the regular trapezoid shape is small and far away from the signal line; and 3, the center of the sawtooth protrusion is grabbed, the sawtooth protrusion is rotated by 180 degrees with the center as the original point, the sawtooth protrusion is changed into an inverted trapezoid shape, the bottom of the inverted trapezoid sawtooth protrusion is small and connected with the signal line, and the top of the inverted trapezoid shape is large and away from the signal line. According to the layout design method with high anti-interference capability, inte
