Detailed Description
Various embodiments of the present application will be described in more detail below with reference to the accompanying drawings. The same reference numbers will be used throughout the drawings to refer to the same or like parts. For clarity, the various features of the drawings are not drawn to scale. Furthermore, some well-known portions may not be shown in the drawings.
The following describes in further detail the embodiments of the present application with reference to the drawings and examples. Numerous specific details of the application, such as construction, materials, dimensions, processing techniques and technologies, may be set forth in the following description in order to provide a thorough understanding of the application. However, as will be understood by those skilled in the art, the present application may be practiced without these specific details.
It will be understood that when a layer, an area, or a structure is described as being "on" or "over" another layer, another area, it can be referred to as being directly on the other layer, another area, or another layer or area can be included between the layer and the other layer, another area. And if the component is turned over, that layer, one region, will be "under" or "beneath" the other layer, another region.
The inventor found that in the prior art, when filling one rectangular pattern (filling unit) into another, multiple polygons (areas to be filled), filling units are filled in the areas to be filled in an array, and then filling units outside the areas to be filled are deleted. When the area to be filled is polygonal, the filling density cannot reach the maximum, and many blank positions exist. In existing layout designs, the pattern of the array can suffer from non-uniformity of etching and over-etching of the pattern at the edges due to the sharp decrease in pattern density at the edge locations. Such that the device characteristics of the edges may not be consistent with the middle. When the integrated circuit is designed as an LCD panel, an OLED panel, or the like, the above situation may cause darkening or lighting of the edges from the perspective of LCD and OLED display.
In order to solve the above-described problems, the inventors propose a new method of graphically filling an area.
According to an aspect of the present application, a filling method is provided. The filling method is applied to the fields of flat panel display layout design, integrated circuit layout simulation design and the like. Fig. 1 shows a method flow diagram of a filling method according to an embodiment of the application. As shown in fig. 1, the filling method according to the embodiment of the application includes the following steps:
in step S101, a region to be filled is obtained, wherein the region to be filled is shaped;
and obtaining the area to be filled, which is shaped like a special shape. The area to be filled is used for laying out filling standard cells, hard cores and other filling cells.
In step S102, pre-filling is performed using different filling schemes, including a first filling scheme and a second filling scheme;
and pre-filling the region to be filled by adopting different filling schemes. The filling scheme may include a first filling scheme, a second filling scheme, a third filling scheme, and so on. Filling units in the area to be filled along a first direction to obtain a first filling scheme; and filling the filling unit in the region to be filled along the second direction to obtain a second filling scheme. Alternatively, the first direction is a horizontal rightward direction and the second direction is a vertical downward direction. The horizontal and vertical are, for example, relative to the integrated circuit layout to be designed.
In step S103, comparing the number of filling units in different filling schemes, and selecting the filling scheme with the largest number of filling units as the final filling scheme;
the number of filling units in the different filling schemes is compared, and the filling scheme with the largest number of filling units is selected as the final filling scheme. Optionally, in the case that the filling schemes have only a first filling scheme and a second filling scheme, the number of filling units of the first filling scheme is a first number, and the number of filling units of the second filling scheme is a second number. In case the first number is greater than the second number, selecting the first filling scheme as a final filling scheme; in case the first number is smaller than the second number, selecting the second filling scheme as a final filling scheme; in case the first number and the second number are equal, one scheme may be arbitrarily selected as the final filling scheme, or the first filling scheme or the second filling scheme may be selected as the final filling scheme according to another rule. Alternatively, the filling schemes are not necessarily displayed on the display interface, and virtual filling may be performed in a computer or the like to obtain and compare the number of filling units in each filling scheme, thereby obtaining a final filling scheme.
In step S104, the filling unit is filled into the area to be filled according to the final filling scheme.
And filling the filling unit into the area to be filled according to the obtained final filling scheme. I.e. the filling of the filling unit takes place along the filling direction in the final filling scheme.
