Detailed Description
The concept and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments to fully understand the objects, features and effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention.
In the description of the present invention, if an orientation description is referred to, for example, the orientations or positional relationships indicated by "upper", "lower", "front", "rear", "left", "right", etc. are based on the orientations or positional relationships shown in the drawings, only for convenience of describing the present invention and simplifying the description, but not for indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. If a feature is referred to as being "disposed," "secured," "connected," or "mounted" to another feature, it can be directly disposed, secured, or connected to the other feature or indirectly disposed, secured, connected, or mounted to the other feature.
In the description of the embodiments of the present invention, if "a number" is referred to, it means one or more, if "a plurality" is referred to, it means two or more, if "greater than", "less than" or "more than" is referred to, it is understood that the number is not included, and if "greater than", "lower" or "inner" is referred to, it is understood that the number is included. If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.
Example one
The basic concept of the invention is as follows: when the Allegro software is used for PCB design, all data after the design file is saved last time can be recovered by using the Allegro.jrl file carried by the Allegro. This file is automatically generated after the Allegro software is opened, and records all operation records after the last execution of the operation of saving the design file, so that the unsaved data can be restored by converting the allegor.jrl log file into a script file (. scr suffix) and then importing the converted script file into the Allegro software.
Referring to fig. 1, a flowchart of a method for recovering unsaved data in this embodiment is shown. The method comprises the following steps:
s100, acquiring a first log file;
s200, screening a plurality of pieces of data meeting preset conditions from the first log file;
s300, processing the plurality of pieces of data to form a second file;
and S400, recovering data according to the second file.
In this embodiment, a description will be given taking an example in which the type of the first log file is a. jrl file, and the type of the second file is a.scr file:
acquiring an allegr.jrl log file from a folder of Allegro software, opening the allegr.jrl log file by using a notebook, wherein all sentences of the allegr.jrl log file start with i, \ t, \ d, \ e and the like, and time is marked in brackets, and the examples are as follows:
\i(00:00:09)move
\t(00:00:10)Select element(s)to move.
\i(00:00:10)pick grid 258.47 3238.58
\t(00:00:10)last pick:260.00 3240.00
\t(00:00:10)last pick:253.11 3225.00
\t(00:00:10)Moving R3/R0402/R0402.
\t(00:00:10)Pick new location for the element(s).
\i(00:00:11)pick grid 288.58 3267.72
\t(00:00:11)last pick:290.00 3270.00
wherein, the statement beginning with \ i is the operation record in the design. Since all statements in the scr file are operation instructions, a plurality of statements beginning with \ i are screened from the file, and the screening result is as follows:
\i(00:00:09)move
\i(00:00:10)pick grid 258.47 3238.58
\i(00:00:11)pick grid 288.58 3267.72
processing the sentences, specifically deleting \ i and time information in the sentences starting with \ i, wherein the processing result is as follows:
move
pick grid 258.47 3238.58
pick grid 288.58 3267.72
thus forming a second file, scr file.
In the Allegro software, the scr file generated by converting the jrl file is read by executing the file-script to recover data, so that compared with the situation that a designer redesigns the content which is not stored, the operation time is reduced, and the working efficiency is improved.
