I have used several EDA software for circuit design.

Recently, some online friends have asked me questions about the choice of EDA software. Let's write them here. It takes a long time to play this role. The words of the family are for reference only.

When talking about the software for Drawing Circuit Diagrams and PCB diagrams, you may first think of PROTEL, which is the most used in Chinese universities, especially Chinese universities, the most relevant references are provided. However, I did not use it first, but I have never used it until now. When I first entered the company, I used the CR-5000 of zuken. It seems that Korean companies use this, at least I saw it all. I feel like a good software. I remember nothing at the time. I thought it was behind the ass of a senior. After reading it for about a month, I will. I will draw it myself. I feel that the shortcut key of this software is quite useful. It is interesting to draw a picture after the speed flies. (later I found that any Eda is familiar with Starcraft ). The poor part of the software is that the picture is ugly, and I don't feel it at first. The comparison between mentor and Cadence is as ugly as it is. Especially that line. It's really not easy to draw a line that doesn't bend. Later, because of the relationship between a project and learn the mentor company software, give me the most impressive is the mouse gesture recognition, other because of the basis of CR-5000, learning is still very fast. Later I used cadence, orcad, some work needs, some self-taught, and not very deep.

The general feeling is that no matter what the software is, it is only a tool in the final analysis. As long as the circuit design method has been learned, it is easier to learn how to use the software. So for beginners, I would like to say: Don't waste time selecting software. Just pick one and use it! This is not important.
