1. Schematic component PCB design
If the required components are available in the PROTEL component library, you can directly locate and place them in the schematic diagram. If the component is not available, you need to create a new schematic component library (Sch.lib). Process: In the original library, find a component with the same (or similar) number of pins as the required component. Place this component in the schematic editing area (i.e., Schdoc file). Click the component, execute the menu command Edit|Copy, and the cursor will turn into a crosshair. Move the cursor to the component and click to set a reference point. Then switch to the Sch.lib file to be edited, create a new device (using the shortcut key to create a component), and modify the name. Click SCH Lib in the lower right corner of the environment.
1. Move the mouse cursor to the empty component name, click the right mouse button, select the Paste command from the pop-up shortcut menu, and paste component 1 into the newly created component. Then modify the pin attributes. Next, execute the menu command Report|Component Rule Check to perform a regulatory inspection.
2. Schematic PCB Design: Create a new schematic file, load the component library (including any custom libraries you’ve created), place the component, and generate the schematic wiring output device report.
3. Component PCB Package Design: Use a component with the same (or similar) package to perform simple attribute modifications to obtain the required component package. This involves copying and modifying the component package from .PCBdoc to .PCBlib. The specifics are beyond this scope. After modifying the component package, execute Edit/Set Preference/pin 1 to set the package reference point at the first pin. Then execute Report/Component Rule Check to ensure all rules are validated, and click OK. At this point, the package is established.
4. PCB Design: Start by creating a new PCB file and import the netlist after loading the package library. Set the PCB size and shape before automatic component layout. Click on the bottom to select the keep-out layer, go to the Place menu, select Draw Line, and draw a rectangle on the black baseboard, choosing the size as needed. Note: The line drawn will be pink, indicating that the PCB size is planned in the keep-out layer. Proceed with automatic layout and routing. Execute Tools/Auto Placement/Auto Placer for automatic component layout. If the above steps are not completed, you will see a status message: “No valid keepout is defined on this board. Autoplacement cannot proceed.”
