Abstract
The invention discloses a method for building a Skill program of PCB (Printed Circuit Board) design layers and films, and belongs to the field of expansion function development performed on the basis of Allegro software. The method aims at solving the technical problem that how to use an expansion Skill interface provided by the software to edit a database, thus realizing some functions which are not provided by the program and improving the Layout work efficiency. The method has the technical scheme that the method comprises the following steps that: (1) in the Allegro software, after a netlist is imported, a layout and wire distribution density parameter report can be obtained; and (2) the number of signal layers of a PCB is determined according to relevant parameters in the step (1) through being combined with the work frequency and the speed of main signals and the type, number and cost performance requirements of signals with special wire distribution requirements.
Description
Technical field
The present invention relates to the expanded function development field that the basis of Allegro software is carried out, specifically a kind of method setting up the Skill program of PCB design aspect and egative film.
Background technology
Have many moneys PCB design software in electronics industry at present, Allegro software, as one wherein, has very abundant and powerful function.This software application exclusive data mode design Storage file, and every part of design document has corresponding self contained data base to support.Two category informations are mainly contained: physical message and logical message in database.The various feature operations of Allegro software are all the editor to this database and operation.Same situation, the expansion Skill interface how using software to provide, carries out editing operation to this database, thus realizes the function that some programs do not provide, and the efficiency improving Layout work is the technical matters being badly in need of at present solving.
summary of the invention
Technical assignment of the present invention is for above weak point, there is provided a kind of and tie the expansion Skill interface using software to provide, editing operation is carried out to this database, thus realize the function that some programs do not provide, improve the method setting up the Skill program of PCB design aspect and egative film of the efficiency of Layout work.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method setting up the Skill program of PCB design aspect and egative film, and step is as follows:
(1), in Allegro software, after importing net table, layout, the report of wiring density parameter can just be obtained;
(2) according to the correlation parameter in step (1) in conjunction with the frequency of operation of main signal, speed, the signal kinds having special cabling requirement, quantity and cost performance requirement, determine the signal number of plies of pcb board;
(3) inside the common scheme of stack design write Skill program, use the signal number of plies of the pcb board determined in this Skill program and step (2), just directly can select the number of plies that will arrange, program just can the good parameter of the number of plies of Lookup protocol and the optimum configurations of egative film.
A kind of method setting up the Skill program of PCB design aspect and egative film of the present invention compared to the prior art, there is following beneficial effect: the various feature operations of Allegro software of the present invention, all the editor to this database and operation, same situation, use the expansion Skill interface that software provides, also can carry out editing operation to this database, thus realize the function that some programs do not provide, improve the efficiency of Layout work.In server PCB design and notebook PCB design, because the restriction of pcb board size, the number of plies many examples of pcb board is as 14 laminates, 16 laminates etc.And the number of plies that corresponding PCB design data exports egative film setting also can increase.According to the method to set up of software, setting cabling aspect, and output egative film can waste a lot of time, arranging with also easily makeing mistakes of repetition.The present invention is inside the common scheme of stack design write Skill program.Use this Skill program, directly can select the number of plies that will arrange, the good parameter of the number of plies of program Lookup protocol and the optimum configurations of egative film, thus increase work efficiency, avoid the problem that mistake is set because the number of plies more.
As can be seen here, the present invention has feature reasonable in design, that structure is simple, easy to use, thus, has good value for applications.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1
(1) revise the menu bar configuration file allegro.men of Allegro software, software default does not install LayoutSkill hurdle, so need to manually add, adds in menu bar by LayoutSkill mono-hurdle; Configuration allegro.men path be C: Cadence SPB_16.5 share pcb text cuimenus; After having revised this project, Allegro software can increase the drop-down toolbar of a LayoutSkill after original menu bar, and the order that we will run can appear in this toolbar.
(2) amendment C: Cadence SPB_16.5 share local pcb under skill
Allegro.ilinit file, add line code wherein: load (" AutoCreateArtowrkFilms.il "), the meaning of this code is for loading this execute file when running menu bar order, and file is called " AutoCreateArtworkfilms ".
(3) AutoCreateArtowrkFilms.il file is put into
C: Cadence SPB_16.5 share local pcb under skill, fill order is by the execute file loaded under this catalogue and run, and this catalogue is the storing directory of Skill file.
(4) in menu bar, perform AutoCreateArtowrkFilms.il order, and by prompting operation, just automatically can create aspect and egative film file, avoid and mistake is set and saves the manual time arranged.
Above-mentioned embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to above-mentioned embodiment; any claims according to the invention and any person of an ordinary skill in the technical field to its suitable change done or replacement, all should fall into scope of patent protection of the present invention.
Except the technical characteristic described in instructions, be the known technology of those skilled in the art.
Claims (1)
1. set up a method for the Skill program of PCB design aspect and egative film, it is characterized in that: step is as follows:
(1), in Allegro software, after importing net table, layout, the report of wiring density parameter can just be obtained;
(2) according to the correlation parameter in step (1) in conjunction with the frequency of operation of main signal, speed, the signal kinds having special cabling requirement, quantity and cost performance requirement, determine the signal number of plies of pcb board;
(3) inside the common scheme of stack design write Skill program, use the signal number of plies of the pcb board determined in this Skill program and step (2), just directly can select the number of plies that will arrange, program just can the good parameter of the number of plies of Lookup protocol and the optimum configurations of egative film.
