Protel、Altium Designer/Mentor pads(easy to control)


PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. The following models are used very frequently, and each has its own advantages and disadvantages.


PROTEL

PROTEL is a CAD software for the circuit industry launched by PORTEL in the late 1980s. It deserves to be ranked in front of many EDA software and is the software of choice for circuit designers. Almost all circuit companies need to use it. The early PROTEL was mainly used as an automatic wiring tool for printed boards. It ran in a DOS environment and had very low hardware requirements. It can run under the 1M memory of a 286 machine without a hard disk. It has fewer functions, only electrical schematic drawing and printed board design functions, and the layout rate of the printed board automatic wiring is also low. The current PROTEL has developed to PROTEL99 (the test version can be downloaded from the Internet). It is a huge EDA software with more than 200 MB installed. It works in the Windows 95 environment and is a complete all-round circuit design system. Contains electrical schematic drawing, analog circuit and digital circuit mixed signal simulation, multilayer printed circuit board design, programmable logic device design, diagram generation, circuit table generation, support for macro operations and other functions, and has Client/Server (client/ Server) system structure, but also compatible with some other design software file formats, such as ORCAD, PSPICE, EXCEL, etc. The use of automatic routing of multi-layer printed circuit boards can achieve 100% layout rate of high-density PCBs.


Altium Designer

Protel is an electronic design automation software developed by Altium in the 1980s for the design of schematics, PCBs, and FPGAs. The software combines board-level design and FPGA design. After 2005, the software was renamed Altium designer. The acquired PCAD and TASKKING became part of altium designer.

Altium Designer series (AD), is a huge EDA software, is a complete board-level all-round electronic design system. But the common problem of AD is that no matter how good the computer is, it always feels that it is not smooth, the software is too big, and there is too much redundancy.


Mentor pads

Pads is a software developed by MentorGraphics, which is relatively easy to use in low-end products and is suitable for the needs of most small and medium-sized enterprises. PADSLayout (PowerPCB) provides an interface with other PCB design software, CAM processing software, and mechanical design software, which facilitates data conversion and transfer in different design environments. The disadvantage is that it is easy to report errors.


Allegro

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

Allegro stands out among similar products. It focuses on high-speed and high-density multi-layer PCB design, but it also has obvious shortcomings. It is difficult to get started. It takes several weeks when all the materials are available and the price is expensive. It is not cost-effective for most small and medium-sized enterprises. .


orcad

orcad is a set of electronic design automation package software on personal computers, which is specially used for electronic engineers to design circuit diagrams and related diagrams, design printed diagrams for printed circuit boards, and circuit simulation.


EWB

EWB is a very excellent circuit simulation software launched by InteractiveImage Technologies Ltd of Canada in the early 1990s, which is specially used for the design and simulation of electronic circuits.

Currently EWB5.2 is commonly used, which is a smaller software (only 16M) compared to other EDA software. But its mixed simulation function for analog-digital circuits is very powerful, almost 100% simulation results of real circuits.

EWB software is an EDA software launched by Interactive Image Technology Co., Ltd. in the early 1990s, but it has only been used in China in recent years. Nowadays, EWB 5.0, which works under Windows 95, is commonly used. Compared with other EDA software, it is a small and exquisite software, only 16M, and its function is relatively single. It is to perform mixed simulation of analog and digital circuits, but you It must not be underestimated, its simulation function is very powerful, almost 100% simulation results of the real circuit, and it provides a multimeter, oscilloscope, signal generator, sweeper, logic analyzer, digital signal generator on the desktop , Logic converters and other tools, its device library contains many large companies’ transistor components, integrated circuits, and digital gate circuit chips. Components that are not in the device library can also be imported by external modules.

Among the many circuit simulation software, EWB is the easiest to use. Its working interface is very intuitive. The schematic diagram and various tools are in the same window. People who have not touched it can use it proficiently with a little learning. The software. For circuit designers, it is an excellent EDA tool. For many circuits, you can know its results without using a soldering iron. If you want to change components or change component parameters, you only need to click the mouse. It can also be used as an auxiliary teaching software for electrical knowledge, which can be used to directly see the output waveforms of various circuits on the screen.


PSPICE

PSPICE is one of the earliest EDA software, launched by MICROSIM in 1985. In terms of circuit simulation, its function can be said to be the most powerful, and it is widely used in China. PSPICE 6.2 is currently used more frequently. It works in a Windows environment and occupies more than 20M of hard disk space. The entire software is composed of schematic diagram editing, circuit simulation, excitation editing, component library editing, and waveform diagrams. A whole, but each part has its own window. Since its development, PSPICE has been merged into ORCAD and became ORCAD-PSPICE, but PSPICE is still sold and used separately. The new version is PSPICE 9.1, which works on the Windows 9x/NT platform, and requires a Pentium or higher CPU, 32M memory, 50M The above remaining hard disk space, 800×600 or more display resolution, is a powerful analog circuit and digital circuit hybrid simulation EDA software. It can carry out a variety of circuit simulation, excitation establishment, temperature and noise analysis, analog control, waveform output, data output, and simultaneously display analog and digital simulation results in the same window. No matter which devices and circuits are simulated, including IGBT, pulse width modulation circuit, analog/digital conversion, digital/analog conversion, etc., accurate simulation results can be obtained.


ORCAD

ORCAD is the EDA software launched by ORCAD in the late 1980s. It is the most widely used EDA software in the world. It is used by millions of circuit engineers every day. Compared with other EDA software, its functions It is also the most powerful. Because ORCAD software uses a softdog to prevent piracy, it is not popular in China, and its popularity is not as good as PROTEL. Only a few circuit designers use it. As early as ORCAD 4.0, which worked in a DOS environment, it integrated electrical schematic drawing, printed circuit board design, digital circuit simulation, programmable logic device design and other functions, and its interface was friendly and intuitive. Its component library is also the richest among all EDA software, and it has always been the first choice among EAD software in the world. ORCAD has become the world’s most powerful company that develops EDA software after the merger of Seven ADENCE last year. Its product ORCAD Century Integrated Edition works under Windows 95 and Windows NT environments, and integrates electrical schematic drawing and printing. Circuit board design, analog and digital circuit mixed simulation and other functions. Its circuit simulation component library has reached 8,500, including almost all general-purpose circuit component modules.
