Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] as attached figure 2 As shown in the schematic diagram of the logical structure of the equal-length matching of high-speed differential signal lines of the present invention, the design method of equal-length matching of high-speed differential signal lines aims at the high-speed differential signal line routing completed by layout routing, and determines that the length of the high-speed differential signal line does not match. The concentrated area of the high-speed differential signal line is then connected to the phase compensation circuit in the concentrated area where the length of the high-speed differential signal line does not match, so that the phase of the signal on the high-speed differential signal line matches and avoids unnecessary winding.
[0025] A phase difference will inevitably occur at the BGA output pin end and the input pin end, and ...
