adence Allegro menu explanation - file Almost every software has a File menu. Next, I will explain in detail the menus that are different from allegro and other software. New Create a new PCB file. After clicking the new menu to enter the dialog box, there are 9 options in the drawing type. Generally, if we design a PCB, we can just choose the default first board. If we want to build a package library, we can choose package symbol. The other 7 options are rarely used. You can understand the literal meaning and know what they mean. Open Open the PCB file you want to design, or the package library file. Recent Designs Open the PCB file you designed, generally refers to the PCB file designed recently or opened. Save Save as Save as, rename. Import The import menu contains many items. The following is a detailed explanation of the commands we often use. Logic Import netlists. The detailed introduction has been introduced in the Allegro basic tutorial series, so I will not introduce it in detail here. Artwork Import .art files exported from other PCB files. Generally, the word command is rarely used. The commands IPF and stream are rarely used, so they are omitted. DXF Import structural element drawings or other DXF files. The import method is as follows: After clicking import/DXF, select in the pop-up dialog box, select the path of the DXF you want to import in DXF file, select MM for DXF units, then check use default text table and incremental addition, and leave the others as default. Then click edit/view layers to pop up a dialog box, check select all, select all for DXF layer filter, that is, to import the information of all layers, then select board geometry in the class below, and select assembly_notes for subclass, because generally the structural element diagram is imported into this layer, then click ok, enter the dialog box that pops up after clicking import/DXF, and then click import to import the structural element diagram. IDF IFF Router PCAD These four commands are rarely used, so they are omitted. PADS generally imports pads when building a library. The sub-drawing command is very powerful and is also a command we often use in PCB design. If we can apply the sub-drawing command very reasonably, it will improve our efficiency in designing PCBs. The import sub-drawing command generally imports the components of the sub-drawing we exported, including wire holes, etc. For example, during the cooperation process, we import the lines drawn by others into the PCB you designed. Generally, the imported and exported files are the same PCB files, that is, the board outline and the relative coordinate zero point are the same. In this way, no matter when we import or export, we always enter the command x 0 0, which is the relative zero point position. Then when we import, we also enter the command x 0 0 and we can import the exported components into the same position. techfile imports the stack exported from other PCB files. placement imports the component coordinates in the PCB file. active times and annotations are rarely used, so they are omitted. pin delay imports the pin delay data of a connector from other PCB boards. The export menu and the import menu are basically the same in usage. Let\'s talk about the differences below.
