Problems solved by technology
However, for non-orthogonal elements, the ports that need to be connected are hypotenuses, so directly using the four directions of up, down, left, and right to specify the port direction cannot find the hypotenuse
If the port is specified by the rotation angle, since the rotation angle is a floating-point number, there is an error threshold problem in specifying a certain angle precisely, and the setting is too cumbersome and not applicable

Embodiment 1
[0049] Below in conjunction with a specific embodiment, the selection method of the non-orthogonal port is described, and the steps are as follows:
[0050] (1) Start the special-shaped wiring command;
[0051] Figure 5 Set interface schematic diagram for wiring port according to the present invention, as Figure 5 As shown, start the River Routing command in the Aether FPD tool, and set parameters on the corresponding page.
[0052] (2) Select two groups of ports that need to be wired;
[0053] Figure 6 It is a schematic diagram of port pre-wiring according to the present invention, it can be seen that the non-orthogonal port of GOA and the orthogonal port of Pixel are connected and matched through pre-wiring.
[0054]This wiring technical scheme can determine its port position in each non-orthogonal unit through the unit name, port process layer, label name and port direction in the master unit, providing basic conditions for subsequent wiring.

The invention provides a definition selection method for a non-orthogonal port in a special-shaped layout. The method is characterized by comprising the following steps of 1) determining a port line segment used for line connection in a master unit; 2) obtaining a rotation angle theta in attributes of non-orthogonal units; 3) performing rotation transformation on the port line segment of the master unit to obtain a transitional line segment; 4) obtaining a translation attribute relative to the master unit in the attributes of the non-orthogonal units; and 5) performing translation operation onvertexes of the transitional line segment to obtain to-be-wired ports of the non-orthogonal units. According to a wiring technical scheme, the port positions in the non-orthogonal units can be determined through unit names, port process layers, tag names and port directions in the master unit, thereby providing a basic condition for subsequent wiring.
Description
technical field [0001] The invention belongs to the field of flat panel display EDA design tools, in particular to a method for defining and selecting non-orthogonal ports in a special-shaped layout. Background technique [0002] In the field of FPD, special-shaped panel design has become a current hot spot. In the initial stage, the GOA (Gate driver On Array, integrated gate drive), DEMUX (multi-channel distribution) and other units placed near the AA area are arranged horizontally and vertically, and the connections between them can be passed through various special-shaped Aether FPDs. The router is complete. With the advancement of EDA technology and the continuous shrinking of panel frame space, a non-orthogonal unit layout method has emerged in special-shaped designs, that is, to place GOA and other units along the curved screen frame, such as figure 2 As shown, the GOA units around the circular pixel area are placed close to the arc outline, and each GOA has been rot...
