1, protel is undoubtedly the first contact eda software, and in most of the universities have protel software programs, but have to admit, protel eda software in the family is indeed one of the most low-end software, making single-sided, two-layer board can still be handy, but began to feel bad 4 layers used, more layers goes without saying that if the face of the high-frequency multilayer high-speed, high-quality board can make protel people are pretty good The :)
protel in the coming days will be eliminated bad that people are now using protel still have considerable market. Learning is the basis for learning high PROTEL pcb software.
2, pads that powerpcb, I call it the low end of the uncrowned king, it is my opinion at the low end of the pcb all the best in a software, easy to use, approachable, quality will not make the board more than wg , allegro and other inferior, now use the widest range on the market a eda software for the needs of most small and medium enterprises.
3, orcad orcad worse than the pcb protel, but part of the schematic design capture CIS orcad is regarded as one of the industry's best schematics tools, interface nice, approachable, easy to operate, simulation and other powerful, if and dxdesigner compared to the use of, I think it is to prevail, but dx have very good management, integrated environment, schematics multiplexed with other functions.
4, wg mentor the company's products, the latest out of the WG2005, windows-based platform, several high-end software is not under a big difference in the merits of the case, only pull cool software is good software in terms of functionality, but WG2005 positive Pull software is succulent, known as the king of the cable, it's very powerful automatic routing, wiring rules designed very professional, expeditionPCB WG is a core part of the pcb, WG2005 contains DX, DC, DV, LIB, EXP and other parts section.
5, en the same as the mentor company's products, latest EN2004, because it is based on unix platform products, but the market is not Chinese textbooks, software, learning more difficult, many people discouraged; professional level it determines that it is not suitable small and medium enterprises, especially small businesses, because there is no need, a bowl of water can extinguish fire Why go the long way to climb to get to the river farther, right, besides the software was originally designed for large enterprises therefore not necessary to worry about having to go to a friend laborious, if the work needed is another matter, schematics is epd2004, basically, it is the most important thing is the integrated management system.
6, allegro high-speed board design facto industry standard!
Protel99se learn it, there are a lot of cracked software, a lot of books, a lot of information, a lot of people to teach you. The disadvantage is that it is too mentally retarded copper function, automatic alignment is too mentally retarded, not destined to do big board. Of course, is only two-panel painting protel99se easiest to use the fastest.
Power PCB can be compared protel advanced a little, you can deal with most of the high-speed boards.
Allegro and mentor dedicated bigger board, because it rules rigorous, powerful, but more difficult to use, but also more than one hundred meters cracked version.
Allegro is the color monotonous point, just started a little uncomfortable. But it's automatic alignment, repair lines, around the same length, walking differential, multi-line and go, repair copper and other functions are very cool with it.
Mentor is to change the graphic design software, color is very rich, the alignment feature is also very powerful, it is said that traces of these eda software features are the most powerful of the.
Mentor and power pcb is the same company's products, a small Japanese favorite with mentor, because it is their own software.
Allegro and orcad is candence products, with many foreign orcad's. Figure drawing with orcad principle in line with international standards, can all eda software compatibility.
