**Circuit Design Software** On **Linux**: ------------------------------------------ As **Linux** OS have become one of the most popular opensource OS for Servers and Desktop, many software will release a **linux** version . It also applies to the **circuit design software** .Since we are using the Linux as our Operationg System , and We would like to search some **Circuit Design Software** Based On **Linux** . So let me introduce some types of Circuit design software in order to make readers more esaily choose their favorite Linux-based software . 1.**EasyEDA** . As a cross-platform **Circuit desgin software** , which is used on the browser and stored on the clound server . EasyEDA provides shematic capture , pcb layout , spice simulation and online pcb order functions which will give you an easy EDA design journey and make your circuit design work more easily and more productively . You could run it on windows , mac , **linux** or android platform ,as long as there is one brwoser on the OS and connecting to network. Let me have a preview of what EasyEDA provides : I.Schematic capture This is a most important function of the **circuit design software** ,almost every **circuit design software** provides schematic capture function . Because it is the basic entrance of understanding the circuit you design . What is more ,it could be used to be converted into pcb design file . Here is a screenshot of one scheamtic : ![enter image description here][1] One Schematic—Arduino 2560 Schematic II.Spice simulaton . There are many spice simulation tools such as Multisim , Proteus, Ltspice , KtechLab . EasyEDA provides many simulation models and the quick way to building models for Integrated circuits . Also ,EasyEDA provides Waveform viewer to preview the simulation results . ![enter image description here][2] Spice Simulation Example . ![enter image description here][3] Spice Simulation Waveform Viewer III.PCB layout Almost all circuit design softwares provide PCB layout function . This is the way to produce the PCB board and the basic tool. EasyEDA provides laying out unlimited pads , size of the boards , and more than 6 layrers of PCB Boards. ![enter image description here][4] PCB Layout IV.Import from third-party EDA Tools EasyEDA can import files from Altium Designer , LTspice ,Eagle, Kicad . V.Export Files EasyEDA can export EasyEDA source ,SVG source ,SVG file ,Image(png),and Pdf files. VI.PCB Order . EasyEDA provides online ordering PCB. When completing your Circuit PCB Design , if you do not want to spend much time on making your own PCB , you could order online PCB . ![enter image description here][5] 2.**DipTrace** The second most popular software running on **linux** I would like to introduce is DipTrace . DipTrace is an EDA software for designing schematic and PCB boards . It is based on Windows ,Mac , **Linux** . The Developers provide mutil-lingual interface and tutorials . DipTrace has 4 modules: Schematic Capture Editor, PCB Layout Editor with built-in shape-based autorouter and 3D Preview & Export, Component Editor, and Pattern Editor. There are some basic Features about DipTrace : I.Simple UI II.Multi-sheet and hierarchical schematics III.High-speed shape-based autorouter IV.Smart manual routing tools V.Wide import / export capabilities VI.Advanced verifications with real-time DRC VII.Real-time 3D PCB preview & STEP export VIII.Manufacturing output There are five modules for DipTrace . ![enter image description here][6] Schematic Capture ![enter image description here][7] PCB Layout ![enter image description here][8] 3D Preview and Export ![enter image description here][9] Component Editor ![enter image description here][10] Pattern Editor 3.**gEDA** gEDA is so important for it is firstly started in an effort to remedy the lack of free software EDA for Linux/Unix . And one of the long standing goal for gEDA is to provide a suite od EDA application for Linux . All applications in the gEDA suite compile and run on Linux. So it is the software that I could not miss on introducing circuit design software on Linux. There are three main features gEDA provides: I.gEDA provides schematic capture : ![enter image description here][11] II.gEDA provides PCB Editor ![enter image description here][12] III.gerber file viewer ![enter image description here][13] Here I should have to mention the term “gEDA Suite”. The term“gEDA”refers to all free software projects and applications that have asscioated with the gEDA project . These include： · gEDA/gaf - gschem and friends (the original project) · PCB - PCB layout program · Gerbv - Gerber file viewer · ngspice - a port of Berkeley SPICE · GnuCap - A modern electronic circuit simulation program · gspiceui - A GUI front end for ngspice/GnuCap · gwave - An analog waveform viewer · gaw - An analog waveform viewer a rewrite of gwave. Works with gspiceui. · Icarus Verilog - A Verilog simulator · GTKWave - A digital waveform viewer · wcalc - Transmission line and electromagnetic structure analysis For the importance of **Linux** to electronic design ,the open-source developers recognize it many years ago , and the gEDA is the proof of their early insight . The gEDA Project remains a federation of software tools developed by different (but sometimes overlapping) programmers. The thread which holds the project together is the shared vision of creating a powerful, community-based, open-source EDA toolkit. 4.**Qucs** Quite Universal Circuit Simulator (Qucs) is an open-source electronic circuit simulator software release under the GPL . It give you the ability to setup a circuit with graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit. Qucs supports a growing list of analog and digital components as well as SPICE sub-circuits. It is intended to be much simpler to use and handle than other circuit simulators like gEDA or PSPICE. ![enter image description here][14] 5**.Magic** Now let me introduce a very-large-integration layout tool originally written by John Ousterhout his graduate students at UC Berkeley during the 1980s. As a free and opensource software ,subject to the requirement of BSD Licence ,Magic continues to be popular because it is easy to use and easy to expand for specialized tasks . Magic is widely cited as being the easiest tool to use for circuit layout, even for people who ultimately rely on commercial tools for their product design flow. ![enter image description here][15] So far I have recommend several circuit design tools on **Linux** . There are also Kicad ,eagle ,Fritzing,Open Circuit Design, and some other kinds of software that can run on **Linux** . As for the restriction of article length, Here I do not list all the **circuit design software** with detailed descriptions . Hope you could enjoy the free and all-platform supported tools like Easyeda, the linux-originated software tool like gEDA, the very-large-integration layout tool like Magic etc .
