Abstract

Provided is a marker setting method. The method must be used for creating a Label in layout design. A single Label font type and font proportion cannot meet requirements of a large-area layout design, and a method for creating a Label through a user-defined font object library is provided for increasing the expandability of the Label font type and optimizing the layout design. In the layout design process, the font object library designed by users is introduced, various characters input into the Label and bound with corresponding units in the font object library through certain design, the types of the fonts read in the corresponding units are adopted as a template when the Label is generated, and the Label is created after the template is resized according to set values in magnification. The characters in the same character library can only be read in once, the creating speed of the Label can be fully improved, and therefore layout design efficiency is greatly improved.

Description

A kind of by create the method for Label with self-defined fontlib

Technical field

A kind of is the method that creates Label in EDA layout design field by the method that creates Label with self-defined fontlib.The invention belongs to EDA layout design field.

Background technology

EDA(electric design automation) be that schematic diagram editing machine or layout editor all provide the function that creates mark in instrument, and this function has been also the requisite critical function of chip design, it can be regarded as the vital signs that engineers stays in the time of design circuit or read circuit, is the language of linking up on circuit or domain each other.

Label is exactly one group of mark being formed by any character and some symbol combination, is used for identifying the port title of device, title or a series of associated metal connecting line of metal routing in domain.Along with the integrated level of chip is more and more higher, the complexity of domain, also in growth at double, is drawn domain efficiency in order to improve, and it is also vital can correctly creating out the mark that meets slip-stick artist's needs.If create the font that Label can only provide with instrument, just become stereotyped, can not revise and expand, and cannot meet the needs of dissimilar layout design person to Label font.Especially at FPD(flat-panel monitor) in this large-area layout design in field, but cabling complex is regular in the extreme, can need continually to create thousands of Label simultaneously, the font only providing with instrument itself, cannot meet FPD design engineer's needs, because Label finally need to work it out with metal level in FPD design, can complete the operations such as test when facilitating subsequent production.Therefore in the live width to Label and Label, the spacing of each character has special requirement, if Label font is too little, after exposure machine exposure, can not make; If font is too large, work it out and take up space too much, cause invalid waste.So can use self-defining font while creating Label, user can write font according to the design rule of oneself, can select dissimilar fontlib at the domain of drawing different size, so not only meet deviser's custom but also improved the display effect of domain, virtually promoted greatly the design efficiency of domain and attractive in appearance.

Here so-called fontlib is exactly to be made up of different like this unit, and a letter, numeral or other identifiers are only being deposited in each unit, and the figure of these characters is all drawn according to design rule by domain slip-stick artist.While creating Label, specify the name of character repertoire, in Label, run into certain character and will read in the data in corresponding units, can deduplication not read in if again run into identical character, the efficiency that has so both improved establishment Label has also met the needs of design.

Summary of the invention

The present invention proposes the method for the self-defined fontlib of a kind of use unit establishment Label, this method is using the datagraphic in the fontlib unit of user's setting as template, in the time creating Label, first from fontlib, corresponding character cell reads in character graphic data, according to this character, the Label font height of the position in whole Label character string and requirement is carried out shift transformation and size conversion again, is finally created in Layout.

Basic thought: first will have a fontlib having designed, this fontlib is can be still must under current startup environment, can find arbitrarily, in storehouse, the character graphics of each unit is script figure or certain symbol that user draws according to design rule and needs, and this storehouse need to comprise the character graphics occurring in establishment Label.Create when Label in Library Name(fontlib name) fontlib of selecting user to specify in a hurdle, in the input frame of Label, write and wish that the content of mark can carry out the establishment of Label.The internal procedure creating is that the each character in sign content is corresponded in fontlib in corresponding units successively, the data of these unit are read in successively and done after certain conversion, can form the Label taking fontlib cell data as template, if certain character does not find corresponding unit in fontlib, can point out user to re-start setting.It should be noted is that in the time that sign content contains identical character, and fontlib does not change, this pattern that just means font does not change, and program just can not removed read data from character cell again, can improve greatly like this establishment efficiency of Label.

Brief description of the drawings

The list of Fig. 1 fontlib character cell

Fig. 2 Create Label arranges interface

Fig. 3 selects self-defined fontlib

Fig. 4 creates the design sketch of Label by fontlib font

Fig. 5 creates the design sketch of Label with default font

Concrete implementation step:

The method that creates Label in conjunction with a concrete example explanation with self-defined fontlib, operating process step is as follows:

1) prepare a fontlib, in storehouse, contain the unit of needed each character, as shown in Figure 1;

2) open Layout, start Create Label order, show the interface that arranges of this order, as shown in Figure 2;

3) Create Label interface is set in Library name mono-hurdle click Browser button, eject choice box and select therein self-defining fontlib, as shown in Figure 3;

4) need in Label mono-hurdle input the sign content creating, the blank space left button in Layout is clicked and can successfully be created Label, as shown in Figure 4;

5) font that use instrument provides creates the Label of identical sign content, and forms contrast with establishment result before, as shown in Figure 5.

Claims

1. a method that creates Label by self-defined fontlib, the principal character that relates to EDA design tool is:

(1) set up fontlib, and create character cell and digital units in this storehouse, in each unit, wish the graph data of the character representing;

(2) in program inside, the relation of mapping is one by one set up in the unit in character and the fontlib that may input in creating Label order, by certain the unit binding in certain character and fontlib in Label input frame;

(3) create in Label process, the data of the fontlib character cell corresponding with character in Label are read in, and the data point of reading in is carried out to displacement and scale transformation.

(4) content of the character string that any character unit combination in character repertoire can be become to arbitrary size and arbitrary arrangement mode in Label is created.

2. the claimed combination with feature (1).

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

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