[Altium Designer Learning]: Create a new Altium Designer project file and draw the resistor-capacitor model and IC components

foreword

Time cannot be met, and Tao cannot be done in vain.

1. AD project file composition

• Schematic library ( .SchLib)
• Schematic ( .SchDoc)
• PCB library ( .PcbLib)
• PCB（.PcbDoc）
• production file ( genber文件)

---

• Click New in the upper right corner of the AD software: (Create four files as shown in the figure in a project respectively, and the genberg file is a production file, which needs to be generated after the board is drawn)
  

• After the creation is completed, there are four files in the project directory:

2. Introduction of component library

Component Model Composition

The component symbol is the representation of the component on the schematic diagram. It is mainly composed of the component frame, pins (including pin numbers and pin names), component names and component descriptions . The electrical connection relationship is established through the placed pins. The pin numbers in the component symbols are in one-to-one correspondence with the actual pins of the electronic components. When creating a component, the graphics may not be exactly the same as the real thing, but for the pin numbers and names, you must strictly follow the instructions in the component specification for one-to-one correspondence.

Drawing component library

• Click the schematic library file, find " Panels" in the lower right corner, and click to select " SCH Library":
  
• There will be a frame of "SCH Library" on the left, and a list of component libraries will appear:
  
• Double-click the component, and the property bar will appear on the right:
  
• You can add components first, and then name them;

• Draw the resistor model ( RES)

  1. Place the pin: ( TABpress enter the property of the pin, you can set the pin number; press 空格键to rotate the pin; after the setting is completed, press to ENTERupdate the change)
     
     

2. Draw the resistance model: (change the grid size to 10 mile, change the size of the resistance)
   
   
   
   
   
3. This basically completes the drawing of a resistance model, and the next step is to add some parameters of the resistance model:

• Draw the capacitor model ( CAP)

Capacitors are divided into ordinary capacitors and polar capacitors.

• The basic steps are similar to drawing the resistor model, and the package (footprint) can not be added for the time being:

IC class component model creation

integrated circuit ( integratedcircuit, abbreviation: IC)

1. Add a new component to the interface of the schematic library, named: Known IC device model:
   
2. Draw a rectangular model:
   
3. Set up the pins and give the pins a name:

hot key:

• New component: T+C
• Alignment of pins: select several pins, press Athe key , and the alignment options will appear, left alignment: L, right alignment:R
