Generally, the majority of electrical devices are made up by a mechanical part and an electronic part. This electrical part consists in printed circuit boards, where the different components are connected by means of copper pathways on a board made of insulating material.The first step to obtain one of these printed circuit boards ( PCBs) is to design it using one of the specific tools on the market. One of the most popular ones is OrCAD.OrCAD is the most powerful and intuitive tool to design printed circuit boards.

Generate the circuit's netlist.3. Import the netlist to ' LayoutPlus'.4. Place the components and trace the pathways.5.
Generate the files of its design.Once the design of the copper pathways on the board has been finished, and we have simulated the behavior of the design, the next step will be to design the PCB from an insulating material, like for example a photosensitive fiberglass board.
OrCAD is one of the most complete and best applications you can find for designing professional electronic circuits, letting you automate those circuits, and generate schematic simulations of all types.With OrCAD you can fix the temperature and other atmospheric elements of the circuit, with the aim of making the simulation totally real. The program pack which OrCAD comes equipped with includes the following: OrCad Capture, OrCad Layout, OrCad PBC editor, OrCad Pspice, OrCad schematics, OrCad Sigxplorer and Specctra for OrCad. With the help of OrCAD you can generate all types of designs: schematics, digital/analogue/hybrid of both simulations, FPGA, CPLD, design synthesis, printed circuits, hierarchic designs, etc. You can use variable electrical components, individually work on each part of the project and optimize certain designs to reduce costs. OrCAD can also do topological analyses, scale to any size, take personalized screenshots of project fragments, and much more.This CAD program is very easy to download, install and then use, through its friendly and intuitive user interface.
You don't need any technical experience at all to get the most out of it.So there you have it. If you want one of the best CAD applications on your desktop, then you need a program like this OrCAD. Dell pci express root complex driver windows 10.
And best of all is that you can download it for free! What are you waiting for?
When PCB is not discovered, all components are connected with wire externally, same as we connect all components on a breadboard. But this increases complexity and size. To solve this issue, PCBs are invented. Now for how to design a PCB, there are many tool and software available online, but out of them, which software suits your application, is discussed here in this article.
We have already learned about in our previous article. In this article, we will discuss and compare some good PCB designing software for their price, usability and other features. Here we are discussing some most commonly used EDA software like EAGLE, Multisim, EasyEDA, Altium design, OrCAD, and KiCAD. These softwares are widely used for PCB designing as well as for simulation of the circuit. Eagle:Most useful and common CAD software for PCB designing is EAGLE.
EAGLE stands for Easily Applicable Graphical Layout Editor. This software was developed by CADSoft Computer but in 2016 EAGLE is taken by AUTODESK now.EAGLE has a very simple, effective and easy interface and provide a library which contains a large number of electrical and electronics components. That is the main reason for being most popular PCB designing software among educationist, hobbyist, and professionals. EAGLE can be installed support on Windows, Linux and MAC platform and also the is available for on website of AUTODESK.Eagle has two editors; Schematic editor and PCB layout editor. The schematic editor is used to add all components and connect according to the circuit requirement. This schematic file has unique features like modular design block, multi-sheet schematic, electronic rule checking and real-time design synchronization.
After this, schematic is directly converted into PCB layout editor, in which we can set components according to less complexity. This PCB layout editor also has some good features like alignment tools, obstacle avoidance, routing engine. These features are available in free version.For professional use, EAGLE provides paid version which is available at 1000$/year. In this paid version, AUTODESK provides technical support that includes call, mail and online chat support and provides access to latest release software. But for educational and self-use free version of this software has enough features.When you install the free version of EAGLE and open it, the first page is control panel as shown in below figure.As shown in above figure, folder name and description of that folder or file are given.
First is Documentation which contains some tutorial documents. Second is Libraries (.lbr), which contain a large list of electrical components. More components are easily available from the internet and, search them and paste into library folder at the installed directory. Next is design block (.dbl), where you can find some inbuilt design of most common circuits which you can directly add to your project. Design rules (.dru) contain rules for track, drill and final copper with important notes and some information. Next is User Language Programs (.ulp) which is used to access data structure and to create an output file.
The user can build their own ULP file. Next is Scripts (.scr), which contains text files with eagle commands and it is very useful for automating a task like drawing a pattern, change of width of all traces. CAM jobs (computer aided manufacturing) (.cam) contains some standard CAM files and the last one is Projects which contains a list of the project with schematic and PCB layout file made by the user.You can also make a Gerber file with the help of eagle. Gerber file is a universal language for PCB designing and this is the last step of PCB designing.Multisim:Multisim is widely used by students and researchers because it contains a powerful research, teaching and circuit design software.
Multisim is advanced, powerful, industry standard, best in class SPICE simulation environment which is most popular world-wide because of their unique features and easy to implement circuit design. If you compare Multisim with eagle, the main advantage of Multisim is that it has a simulation environment which is not available in eagle but if you compare for only PCB designing purpose, eagle has good platform compared to Multisim.Multisim was developed by electronics workbench and interactive image technology. At that time, this software is just used to teach electronic programs in colleges, this software was not much used for industrial applications but after some features add by National Instrument and it has widely accepted by professionals and educators. Multisim is available in two additions; one is made for students and educators and second is made for professionals and industrial purposes.Multisim enhances powerful simulation technology with the ability to analyze analog, digital and power electronics across education, research, and design.

This software has functionality like all-new parameter analysis, integration with new embedded targets and simplified design with user-definable templates. Multisim Standard Service Program (SSP) customers also have access to self-paced online training.You can download the.EasyEDA:is a web-based Electronic design automation (EDA) tool. It is a web-based tool, so no need to download or install any software. To use EasyEDA, you have to open easyeda.com only, from any HTML5 capable web browser and it doesn’t matter that which OS you are using, it can be used in windows, Linux, MAC. Only you require is web browser like Chrome, Firefox, Safari, Internet Explorer and Opera but it is recommended to use this in chrome or firefox for better performance. This is the biggest advantage of EasyEDA.EasyEDA provides features like; simple, user-friendly and it is a very good platform if you don’t have much knowledge about PCB designing and it can use at anywhere, anytime and from any device.
One advantage of this site is, it has large numbers of open source projects, which is easily available from the internet and also very good tutorials are available in EasyEDA official website. Even we have developed many using EasyEDA here in CircuitDigest. It has more than 500000 libraries with symbol and footprint of components and also has a feature to create your own component if it is not available in the library with symbol and footprint. One more advantage is, it can support other software libraries and schematic which includes Altium, EAGLE, LTspice, and DXF.When you open this link, it will look like below screenshot. In this editor you find navigation panel, toolbar, workspace, drawing tools, writing tools any many more functions. The great ease of Eagle is the use of short-keys which are all custom definable. With your left hand on the function keys and right-hand on the mouse, you can make a PCB-layout much faster and easier then in Altium!Furthermore the portability of a Altium design to a different computer (at home) is very bad.

The stupid use of libraries is to complicated in Altium.The biggest mistake in Altium is to put all component parameters inside the Altium Library! As if it were an ERP.!So I'd say Altium is very un-flexible in use. I think it was made for project managers to show how well everything is integrated: 3D, BoM, ODB+ etcetera.But end of the day we use a 3D Cad program like solid-works or similar for 3D, and Excel in combination with an ERP for BoM. So to integrate this into one software is a dumb decision in my opinion!.
