Schematic design software

OrCAD is enough. There are many Netlist supported, which is basically the industry standard.

PCB layout software

Protel, now the main push is Altium Designer

The mainstream of low-end design in China is hardly used abroad. It is easy to learn, suitable for beginners, easy to start; it takes more system resources and requires higher computer configuration. There is still a considerable market for people who use Protel in China.  After all, the hardware circuit design of small and medium-sized companies is still low-end.  However, it is recommended that you contact and learn other software with better functions as soon as possible.  Don’t always linger at a low level, which is not very friendly to salary.

Altium designer winter 09 provides the only unified application scheme, which integrates all the necessary technologies and functions required for the integrated development of electronic products. Altium designer winter 09 integrates board level and FPGA system design, embedded software development based on FPGA and discrete processor, and PCB layout design, editing and manufacturing in a single design environment. With the integration of modern design data management functions, Altium designer winter 09 becomes a complete solution for electronic product development - a solution that meets both current and future development needs.

PADS

Pad software is also used by quite a lot of people.  It is easy to use.  I feel that it is much better than Protel. It is suitable for medium and low-end design, and can be called the king without crown in the low-end. Now the most widely used EDA software on the market is suitable for the needs of most small and medium-sized enterprises. It has no simulation itself.  When making high-speed board, we should combine other special simulation tools, such as HyperLynx.

Pads software is the circuit schematic diagram and PCB design tool software of Mentor Graphics company. At present, the software is one of the main circuit design software used by engineers and technicians engaged in circuit design in China, and it is the most commonly used tool software for high-end users of PCB design. As the mainstream PCB design platform in the industry, the pads layout / router environment of Mentor Graphics company has been widely used in the most active industrial fields such as communication, semiconductor, consumer electronics, medical electronics with its powerful interactive layout and routing function and easy to learn and use. PADS Layout/ Router supports a complete PCB design process, covering the import from schematic network list, interactive layout and wiring driven by rules, DRC/DFT/DFM verification and analysis, until the final production file (Gerber), assembly file and BOM output and other comprehensive functional requirements, so as to ensure that PCB engineers complete the design tasks efficiently.

Cadence allegro

The actual industry standard in high speed board design. No matter what, it’s super good. PCB layout tool is absolutely first-class.  After a little familiar with it, you don’t want to use other tools.  The wiring is super cool. Simulation aspect is also very cow, has its own simulation tool, Signal Integrity simulation, Power Integrity simulation can do. In the PCB high-speed board firmly occupies a dominant position. You know, 60% of computer motherboards and 40% of mobile phone motherboards in the world are drawn with Allegro!

Cadence’s electronic design automation products cover the whole process of electronic design, including system level design, functional verification, IC synthesis and layout, analog, mixed signal and RF IC design, full custom integrated circuit design, IC physical verification, PCB design and hardware simulation modeling.

Cadence Allegro system interconnection platform can co design high-performance interconnection across integrated circuits, packaging and PCB. By using the platform collaborative design method, engineers can quickly optimize the system interconnection between I / O buffers and across IC, package and PCB. This method can avoid hardware rework, reduce hardware cost and shorten design cycle. The constraint driven Allegro process includes advanced functions for design capture, signal integrity, and physical implementation. Because it is also supported by cadence encounter and virtuoso platform, Allegro collaborative design method makes efficient design chain collaboration come true.

Board level circuit design system

It includes schematic input, generation, analog digital / hybrid circuit simulation, FPGA design, PCB editing and automatic layout, MCM circuit design, high-speed PCB layout design and so on. include:

*Concept HDL schematic design input tool, including for NT and for UNIX products.

*Check plus HDL schematic design rule checking tool. （NT & Unix）

*Spectra quest Engineer PCB layout planning tool (NT & Unix)

*Allegro expert expert PCB layout editing tool (NT & Unix)

*Spectra expert Autorouter expert PCB auto routing tool

*Signoise signal noise analysis tool

*EMC checking tool for EMC

*Synplify FPGA / CPLD integrated tool

*HDL analyzer

*Advanced package designer advanced MCM package design tool

Mentor WG

It is slightly inferior to Cadence, but it is also a top-level tool.  It aims at high-end circuit design, and also has its own simulation tools. However, in China, its support providers are relatively small, not as much as Cadence. Now it’s time to change to Mentor EE2009.

Mentor WG is a PCB design tool based on Windows NT / 2000 platform of mentor graphics company. It covers the design process from design creation, layout to product processing.  At the same time, the designer can carry out schematic simulation, high-speed circuit analysis, board level thermal analysis, library development and management.

I don’t mention the others.  There are few people who use them. After all, it is relatively easy to use PADS. If you often make high-speed boards, it is recommended to choose CADENCE.  One is that cadence is more used in domestic high-speed boards. Second, because it is popular, there are more people to learn and communicate with. Many big companies use it.  The salary of Protel is different from that of Cadence Allegro.
