Abstract

In the layout design process, Labels need to be established to mark the port name of each device, or the name of each kind of metal wire or the position information with special meanings in a layout. However, with the improvement of technologies, wiring becomes increasingly delicate, and space for placing the Labels becomes increasingly narrow. To place the Labels more reasonably in extremely small space, guarantee that the Labels are arranged in the same direction as that of the metal wires, and guarantee that other surrounding objects are not disturbed, the invention provides a self-defining type label character arranging method. According to the method, the established Label character arranging method can be selected in an arranging direction according to the space for placing the Labels in a layout and the direction of metal wires during layout drawing, and in this way, the error rate is reduced during layout drawing, the readability of the layout is improved, and a large amount of time is saved for layout design.

Description

The self-defining Label character arrangement mode of a kind of support

Technical field

Support self-defined Label(mark) arrangement mode of character is the method that can change Label character arrangement mode that creates in EDA layout design field.The invention belongs to EDA layout design field.

Background technology

EDA is the abbreviation of electronic design automation tool, conventionally contains editting function module, copying module and physical verification functional module at the eda tool towards integrated circuit (IC) design field.Wherein editting function module is generally divided into domain (Layout) editing machine, schematic diagram (Schematic) editing machine and symbol figure (Symbol) editing machine.

At IC(integrated circuit) design or FPD(flat-panel monitor) in design process, layout design is the link of a physics realization, is also the great shift of a circuit diagram from symbolism to actual physics figure layer.Along with the continuous lifting of manufacturing process, the complexity of technique is multiplied especially, and it is more and more that number of metal also becomes, and reduces power consumption in order to improve integrated rate, and the area of chip is also more and more less, makes layout design more and more challenging.How can in huge domain, find the port of some devices or the implication of any cabling representative of mark, create Label(mark) be exactly the Gospel addressing these problems.For layout design person, create various Label(mark) draw a requisite instrument in domain process.Label is the message identification of the different figure layers of diverse location, draws in domain process, need to be accustomed to constantly creating Label according to the mark of principle diagram design, the drafting real-time information of domain and slip-stick artist's design and identify.Label can be made up of any English character and numeral and some basic symbols, and the length of Label does not limit in theory, but because an inch of land is an inch of gold and complexity in the domain of chip are high especially again, conventionally can identify with minimum character.If layout design person wants to place on very narrow cabling the Label that contains several characters, or place the Label consistent with its direction according to the metal routing of different directions, only have at present by after Label upright character is rotated and be placed on these positions, but postrotational Label, character be wherein likely just stand upside down or lie down, so very inconvenient deviser carries out drafting or the reading of domain.Thereby support the character arrangement mode of self-defined Label, and can easily Label be placed in domain to narrow space arbitrarily, domain slip-stick artist also can be according to the arrangement mode of the suitable Label character of the route selection of metal wire.

Summary of the invention

The present invention proposes a kind of arrangement mode of supporting self-defined Label character, this method can be selected arrangement mode and the direction of Label character as required, in the process that creates Label, the orientation meeting of each character of sign content is arranged according to the direction that inner selection is set, and after having created, character in each Label is upright, nonoverlapping, and in Label, entanglement can not occur because of the change of arrangement mode putting in order of character yet.

Basic thought: while creating Label, in input frame, the character string of mark is wanted in input, and at Arrange Direction(arrangement mode) selection right, the Label creating under this arrangement mode is out being placed in domain that in sign content, each character is arranged successively from left to right, and each character is upright; If selected left in Arrange Direction, create after Label success, each character in Label can arrange from right to left successively, and putting in order not of character can the entanglement because of the change of arrangement mode, has ensured that domain slip-stick artist creates the primitive meaning that Label need to express; If select upwards in Arrange Direction, in Label, the arrangement mode of character is to be arranged in order to be from top to bottom placed in domain; If select downwards, in the Label of establishment, each character can arrange successively from top to bottom and be placed in domain.No matter select which kind of arrangement mode, Label can be set to the arbitrary height in domain allowed band, and after creating successfully under every kind of pattern, each character of Label the inside there will not be overlapping, and can ensure that character is all upright.

Concrete implementation step:

The establishment Label method that self-defined Label arrangement mode is described in conjunction with a concrete example, operating process step is as follows:

1) in a storehouse that has technique, create a Layout unit and open.

2) order of startup Create Label, and the interface that arranges of opening this function, as shown in Figure 1;

3) input needs the Label creating, as: ABCD, and select orientation in Arrange Direction, be arranged as example with left, as shown in 2 figure;

4) mouse is shifted out to form, and blank space in Layout clicks and create Label, result as shown in Figure 3;

5) use the Arrange Direction mode of acquiescence to create Label, result as shown in Figure 4.

Claims

1. support a self-defining Label character arrangement mode, relate to EDA design tool character after creating Label is carried out to self-defining arrangement mode.Its principal character is:

(1) upwards, in the Label of generation, character is arrangement mode from top to bottom successively to direction;

(2) direction is downward, and in the Label of generation, character is arrangement mode from top to bottom successively;

(3) left, in the Label of generation, character is arrangement mode from left to right successively to direction;

(4) to the right, in the Label of generation, character is arrangement mode from right to left successively to direction.

2. the claimed combination with feature (1), (2), (3), (4).
