How to get started with protel 99se

 

Although there are many textbooks for protel 99se, a large book is too detailed. New users often don't know how to focus on it. Haha, the following is my usual experience. A simple power supply is used as an example to describe the most basic operations from scratch. After learning, you can draw your own version. Of course, the protel 99se operation is far more than that. The individual must continue to practice more and learn more from others' experience. Let's talk about it. Let's start the lecture !!! Students. Pai_^
First, open protel 99se. Anyone who opens the computer will perform this operation. Pai_^

Go to the main interface

Create a project file

Next step

Here you can change the storage path of your files. Don't know where to put it. Haha
Click browse)

Rename your name.

Click file-new. To create a new file, select new instead of new design)

Choose the new file type, mainly to create a new schematic or a new PCB File
Create a new schematic File

Double-click to enter the schematic drawing interface

The component selection box is displayed on the left, including the library to be added. The component list of the selected library is shown below. Double-click the model and selected component and click place to place the component in the schematic. You can press the tab key on the keyboard to enter the Component Attribute Modification page. Enter the following information about the component attributes.

In schematic drawing, the attribute of the component is very important, which determines the actual publishing effect. To put it simply, component encapsulation must be accurate. There are many ways to edit the component attributes. Double-click the component and right-click the component to select the attribute or press and hold the component, and then press the tab key.

Fill in the encapsulation footprint (key), component number designator, and model part type. Be sure to fill in all the pcb Component Libraries you have added. Otherwise, an error occurs.

After filling in ···

Place all the components. As for how to place the components, you can place them as you think they are nice. During the placement process, press the Space key to change the angle. The shortcut key ctrl + x is the component image.

For example, 7905, You can first turn the first foot to the top, and then ctrl + x.
If some components are not labeled during component placement. In this case, you can use the automatic label function.
Click tool-annotate in the menu bar

Enter the label page

Selected? Parts, and then OK. A list is displayed, indicating the label. Close is.

After the components are placed, the next step is to connect them. Click the tool.

After all the cables are connected, the schematic diagram is drawn. The next step is to create a network table for the PCB, and draw a schematic diagram to get it. Pai_^
Click design-create netlist.

Open a dialog box. OK is
Pai_^

A list is displayed, which is the content of the network table. It can be modified. However, it is generally not necessary. When you become a master, you will naturally know how to change it.

The schematic diagram has come to an end. Next we will enter the most interesting PCB cabling stage that best reflects your level.
Or new (new). You can create a menu. You can also right-click new in the blank area (some Chinese versions cannot be right-clicked)

Select PCB type

In this step, some people like to use a wizard to draw a PCB, but I know that the Wizard is more convenient and accurate, and the wizard can quickly help you draw the size of the Board. Let's take a look.

Double-click the PCB tab. If you do not use the Wizard to create a PCB. First, define the physical size of the Board and draw a box on the keepout layer.


Next, define the cabling rules, including the line width and safe distance. Generally, the default value is "deprecate width". The default line width is not very fine. Pai_^
Right-click and select rules

Pull to the end and find width · double-click this item to create a rule, including global or network settings (such as ground network)

Double-click the following rule to define the global line width rule,


Okay. After a sigh of relief, I loaded the network table and started working.
Design -- load nets

Search network tables

If there are no encapsulation or label errors, all macros validated is successfully loaded. Otherwise, the system displays the number of errors and the error type is displayed. Generally, errors are caused by encapsulation failure or incorrect ID. A typical example is diode. In the schematic diagram, the two parts are 1 and 2, while the components in the PCB library are A and K. An error will occur if you are not able. You can just change it to make it consistent. It is not detailed here.

Click execute below to see the result? Make full use of your wiring level.

On the PCB cabling interface, you can draw multiple curved lines and press shift + space to change the lines.

I have a lot of knowledge about PCB wiring. I can't say more about cainiao. You can only say something basic.
The first is the setting of the work environment. As long as the visual grid size is set, the component unit is obtained. Smallest unit of movement of components, etc.
Right-click options -- board options

You can select the layer to be displayed. Generally, the default value for a single panel is. The lower right foot is the unit that changes the visual grid. The upper one is a small grid, and the lower one is a large grid.

Select the second item above.
Select the unit system from the drop-down menu in the lower-right corner, whether it is in the metric or imperial system (you can also change it under view -- toggle units in the menu bar, and click change once)
Page, you can modify the unit of the captured component. The smallest unit for moving a component. (Four items on the left)

After the configuration is complete, enter the wiring work. The first is the attribute setting of the component (Optional). Sometimes, when there are too many components, the component label and model characters will block your line of sight. At this time, you can change the font size or even hide it.
Double-click component

Click change global to change the font size. Under change scope, select All · (All). To hide characters, select hide.

Click OK to complete the modification. A dialog box is displayed, Which is yes.

Make sure that the layer settings are correct when you draw a wire. Generally, a single panel is drawn under a bottom layer. The top layer of the double panel is the top layer. You can click the following button to change the layer, but the shortcut is simple and clear, especially when you draw a pair of panels (Haha, I have never painted a pair of panels for personal plate-making ...) Especially easy to use. You can change the value by pressing the "add" and "Subtract" key on the right-side keypad. You can use the jumper to pull a single panel. Pai_^
Layout: whether a Board is successful or not. It usually takes several modifications. You can first deploy the rough layout, wiring, and changing the layout while wiring.
Here, we will prompt you to select the right wire painting tool. The first one is wiring the dot with a network and cannot be connected without a network connection. This ensures that you have not drawn the wrong line. Second, there are no network restrictions. You can draw any image, but it is generally not used.

After the network is connected to IOT platform at two points, the network lines in principle are automatically eliminated. This can be used as a test method for wiring.

After your constant efforts, hard work, and constant modification. Should your board be beautiful?
In summary, the schematic diagram should be accurate, the encapsulation should be correct, and the component labels should not be repeated. Patience is required for PCB cabling. Do not make any mistakes and cause bugs.
These are my personal experiences. It is simple for the man who will use protel 99se, but I believe it will be helpful for those who have never touched protel 99se. I hope I can help some people. Don't laugh at me.
