Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A method of simplifying rpt file generation, comprising:
and S1, setting the ECL attribute of the DDR signal to be true in an Allegro file.
As shown in fig. 1 and fig. 2, the Allegro software is opened, Edit and Properties are selected in sequence, DDR data to be exported are selected, an Edit Property interface is popped up, Available Properties on the left side of the Edit Property interface select Ecl, and the Ecl attribute is set to True. In the Allegro software, the DDR table can extract the length of the network only when the ECL is set, and the DDR table cannot extract the length of the network unless the ECL attribute is set.
And S2, creating a generated tool file, and writing an rpt file generation command in the generated tool file.
As shown in FIG. 3, the initial format of the generated tool file is the txt format. And after the txt format file is created, writing an rpt file generation command into the generation tool file, and when the generation tool file runs in Allegro software, operating the rpt file generation command, so that the BRD file import path and the rpt file generation path can be correctly obtained through locking information and generation information, and the corresponding rpt file is generated. .
The rpt file generation command includes:
and T1, creating the rpt file generation command according to the own command of the Allegro software.
And (3) creating a new rpt file generation command by using the axlCmdregister function, and generating a tool file to achieve the purpose of generating the rpt file by operating the rpt file generation command.
And T2, acquiring the environment variable value of the Allegro software by utilizing the own command of the Allegro software, locking and searching the directory address, and simultaneously requiring the following commands to be completed in the Allegro software.
The environment variable value of the Allegro software is obtained through an axlGetVariable function, the getWorkingDir function searches a directory address, and the axlShell function requires that the following commands are all completed in the Allegro software.
And T3, obtaining locking information and generating information content.
The locking information comprises a BRD file import path, and the step of obtaining the BRD file import path comprises the following steps:
and A1, determining the version number of the Allegro software according to the acquired environment variable value of the Allegro software.
And A2, obtaining the BRD file name by searching the file with the specific format. In this step, the rpt file generation command obtains the BRD file name through the axlCurrentDesign function.
And step A3, setting a condition command, and obtaining a BRD file import path according to the matching of the version number of Allegro software and an installation rule. Because the installation path of the Allegro software has a rule, the corresponding BRD file import path can be known only by determining the version number and the BRD file name, so that path prefixes corresponding to the version numbers of a plurality of Allegro software can be preset, and the complete BRD file import path is obtained through a character splicing function.
The generated information comprises an rpt file generating path and a generating format, the rpt file generating path is consistent with the BRD file importing path of the locking information, the generating format is the rpt format, and the generated rpt file is named according to the BRD file name obtained in the step A2, so that the file name of the rpt file is the same as the file name of the BRD file, and the correspondence at the later stage is facilitated. And when the DDR data information extracted by the own command of the Allegro software is called, displaying the DDR data information in an rpt file according to the path association.
And T4, calling a self-contained command of Allegro software to extract DDR data information in the BRD file to generate an rpt file according to the locking information and the generation information. Since all the data is required to be completed in the Allegro software after the step T2, the DDR data information in the BRD file can be extracted in direct association with the own command calling the Allegro software.
And S3, modifying the format of the generated tool file into a file format which can be identified by an Allegro file. In step S3, the format of the generation tool file is modified to the format of il. The generated tool file can be directly stored as an il format file after being written into an rpt file generating command, or the suffix file format of the generated tool file originally in the txt format can be directly modified and changed into the il format file.
The il format can be recognized and run by the Allegro software, requiring the generation tool file to be executed in the Allegro software in coordination with the axlShell ("set nonconfirm") command used in the data extraction command, so that the function can be used directly with the Allegro software.
And S4, opening Allegro software, loading and running a generation tool file, and generating an rpt file in a set directory.
In step S4, further comprising,
and B1, storing the generated tool file into a folder capable of being identified by the Allegro file, namely storing the generated tool file into a pcbenv folder.
And B2, opening an env command of the Allegro software, and associating the generated tool file with any one quick start key.
And B3, pressing a quick start key in Allegro software, and generating an rpt file in a set directory.
After the setting is completed, the generated tool file is associated with a certain shortcut start key by matching with a shortcut key control function carried by Allegro software, and a user can use the shortcut start key to operate the generated tool file in a one-key mode in an Allegro software interface to generate the rpt file. The method can improve the efficiency of generating the rpt file, and especially can save a great deal of time of designers when a great deal of rpt file is required to be generated.
And if the BRD file is in a locked state, popping up a warning window prompt in the process of operating and generating the tool file. When all DDR data are extracted by the generated tool file and no locking state or other unexpected conditions are met, after the generated tool file is operated, a prompt window pops up on an Allegro software interface.
As shown in fig. 4, the rpt file contains coordinate information of each point (VIA hole) of the DDR signal and length information between the points. The DDR signals are separated by dotted lines to form a plurality of columns of signal information tables, each column comprises the name of each VIA hole in the DDR signals, the coordinate of the VIA hole and the length between the VIA holes, one column of length information corresponding to the VIA holes indicates the distance between the VIA hole and the VIA hole on the uppermost layer of the DDR signals, and the last display statistical result of the column where the DDR signals are located comprises the number of the VIA holes contained in the DDR signals and the total length of the signals.
In a specific embodiment, the contents of the written rpt file generation command are specifically as follows:
the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
