Online Drawing of Circuit Board-How to Draw Circuit Diagram Based on Circuit Board

What are the circuit board drawing software? 1、protel

Protel is EDA software launched by Altium Company in the late 1980s. In the CAD software of electronic industry, Protel is well-deserved ahead of many EDA software, and it is the first choice for electronic designers.

It has been used for a long time in China and its popularity is the highest in China. Some electronic majors in colleges and universities have specially set up courses to learn it, and almost all electronic companies are using it. Many large companies often write in the condition column that they will use PROTEL when recruiting electronic design talents.

2、powerpcb

Powerpcb is the circuit design automation software promoted by MentorGraphics Company of the United States, and it is also one of the most widely used and excellent EDA software in the field of electronic engineering.

Software for designing and making printed circuit board negatives is used in conjunction with PowerLogic to support various electronic parts, such as resistors, capacitors and various ICchip. PowerPCB is different from PSpice in that it can simulate line characteristics, but the former can't.

3. Allegro

Allegro is an advanced PCB design and wiring tool introduced by Cadence. Allegro provides a good interactive working interface and powerful and perfect functions. Combined with its front-end products Cadence, OrCAD and Capture, Allegro provides the most perfect solution for the current high-speed, high-density and multi-layer complex PCB design and wiring.

4、orcad

Orcad is a set of electronic design automation software for personal computers, which is specially used for electronic engineers to design circuit diagrams and related charts, design printed diagrams for printed circuit boards, and simulate circuits.

5、EWB

EWB is an excellent circuit simulation software launched by Canadian InteractiveImageTechnologies Co., Ltd. in the early 1990s, which is specially used for the design and simulation of electronic circuits.

EWB5.2 is widely used at present. Compared with other EDA software, it is a relatively small software (only 16M). However, it is very powerful for mixed simulation of analog-to-digital circuits, and the result simulation of real circuits is almost 100%.

What are the simple and easy-to-use softwares for drawing circuit diagrams?

Yi Tu Graphic is a comprehensive office drawing software. It has 260+ drawing types, including flow chart, organization chart, UML diagram, circuit diagram, floor plan and so on.

Second, Visio

Visio is a professional drawing software owned by Microsoft, which follows Microsoft's Office style, is classic and concise, and its layout is basically the same as that of Office, making it very easy for users to get started.

Three. Quangraffle

OmniGraffle is a professional drawing software produced by TheOmniGroup, which also has rich functions and many adjustable graphic attributes. However, in terms of drawing types, it is less than billion-figure icons and Visio. For example, the common lane map is not native in OmniGraffle (but it can also be drawn manually).

Fourth, the process

ProcessOn is an online drawing tool that users can use without downloading and installing. The biggest feature is online collaboration (for a flowchart or prototype, team members can collaborate and modify it in real time, and these files are stored in the cloud).

Five,

Is a foreign online drawing tool (with PC client), the biggest feature is that it is open source, completely free, and can be used online without even registering and logging in. Although the software is completely free, the product capability is not inferior to ProcessOn.

How to draw the circuit diagram 1 according to the circuit board? Connect the circuit board function.

2. Read the chip data of important integrated chips on the circuit board to understand the chip function and its role in this circuit.

3. Divide the circuit into modules and ensure that each component on the circuit board is assigned to a module. For example, there may be power module, main control module, signal acquisition module, display module and so on in the circuit. And use multimeter to measure the components in the circuit that are not easy to be divided into modules.

4. According to the divided circuit modules, start to draw the circuit diagram of each module.

5. Draw the circuit diagram to ensure that no components are pulled down. Check the circuit diagram after drawing to make sure it is correct.

6. Analyze the circuit function to ensure the correctness of the circuit.

If the final analysis shows that a function is different from the typical circuit given in the chip data, it may be that you have made a drawing error and need to check it.
