  • Experiences in Using Open Source Software for Teaching Electronic Engineering CAD
    Experiences in Using Open Source Software for Teaching Electronic Engineering CAD Dr Simon Busbridge1 & Dr Deshinder Singh Gill School of Computing, Engineering and Mathematics, University of Brighton, Brighton BN2 4GJ [email protected] Abstract Embedded systems and simulation distinguish modern professional electronic engineering from that learnt at school. First year undergraduates typically have little appreciation of engineering software capabilities and file handling beyond elementary word processing. This year we expedited blended teaching through the experiential based learning process via open source engineering software. Students engaged with the entire electronic engineering product creation process from inception, performance simulation, printed circuit board design, manufacture and assembly, to cabinet design and complete finished product. Currently students learn software skills using a mixture of electronic and mechanical engineering software packages. Although these have professional capability they are not available off-campus and are sometimes surprisingly poor in simulating real world devices. In this paper we report use of LTspice, FreePCB and OpenSCAD for the learning and teaching of analogue electronics simulation and manufacture. Comparison of the software options, the type of tasks undertaken, examples of student assignments and outputs, and learning achieved are presented. Examples of assignment based learning, integration between the open source packages and difficulties encountered are discussed. Evaluation of student attitudes and responses to this method of learning and teaching are also discussed, and the educational advantages of using this approach compared to the use of commercial packages is highlighted. Introduction Most educational establishments use software for simulating or designing engineering. Most commercial packages come with an academic licence which restricts access to on-site computers.

Tarkoituksena oli myös selvittää, mitä avoimen lähde­ koodin ohjelmia, ohjelmistoja ja käyttöjärjestelmiä voidaan käyttää kaupallis­ ten sijaan. Valitsin aiheen oman kiinnostukseni mukaan. Kiinnostuin avoimesta lähde­ koodista, kun aloin itse käyttämään Ubuntua käyttöjärjestelmänä. Huomasin kuinka kehittyneitä avoimen lähdekoodin ohjelmat, ohjelmistot ja käyttöjärjes­ telmät ovat, joten halusin tutkia kuinka paljon näitä hyödynnetään alallani. Tutkimusmenetelmäksi valitsin lomakehaastattelun, jonka tein verkkokyse­ lynä Limesurvey ­ohjelmalla. Limesurvey on avoimen lähdekoodin ohjelma, jolla voi tehdä kyselyitä ja analysoida niitä.

    Home Forums Datasheets Lab Manual Testing Components Buy Project Kits Custom Search jojo November - 6 - 2011 31 Comments Hello friends, I hope you all got benefited with our previous article on Electronic circuit drawing softwares . Today we are bringing you a great collection of circuit simulators – which are at the same time can be used for circuit drawing, circuit design and analysis as well. The list is well structured as free circuit simulation softwares, open source circuit analysis and simulation software, simple and easy to use simulators, linux based simulator, windows based simulator etc. Finally after researching through all the list we have compiled a collection best circuit simulation softwares as well. So lets start our journey right below. Free and Open source circuit simulator software list:- 1 of 13 NgSpice – one of the popular and widely used free, open source circuit simulator from Sourceforge. NgSpice is developed by a collective effort from its users and its code is based on 3 open source software packages:- known as:- Spice3f5 , Cider and Xspice. Ngspice is a part of gEDA project which is growing every day with suggestions from its users, development from its contributors, fixing bugs and approaching perfection. As its a collaborative project you can suggest improvement of the circuit simulator and be a part of the development team. GnuCap - is another open source project, developed as a general purpose circuit simulator. Known widely as GNU Circuit analysis package, this linux based circuit simulator performs various circuit analysis functions as dc and transient analysis, ac analysis etc. Developers have incorporated spice compatible model for MOSFET, BJT and Diode.
