It may have improved since then it's pretty much the only program in active development. Download part schematic, PCB footprints and 3D models for FREE + Add it to your ECAD Tool. Altium is also a decent option, though I found its PCB capabilities to be significantly worse than Orcad/Allegro last time I used it (~2006). Another option to consider is the Mentor tools, particularly for PCBs. The PCB tool is quite good, though it has a huge learning curve. Orcad has its learning curve, but it might just be the best bang for the buck, particularly for schematic entry. I've seen several boards ruined by Eagle's incompetent handling of ground planes, so definitely check your gerbers before sending anything out. Eagle is a slightly more sophisticated version of FreePCB, with an even clunkier UI and lots of useless features that tend to bite you in the ass (the "CAM Processor" is a case study on how not to design a piece of software). For simple PCBs, I like FreePCB, though it's got some issues and there's no matching schematic editor (I suppose there's tinycad, but it's kind of a piece of crap). Not sure about Kicad, haven't really used it. The PCB tool is straight from the 80s and is basically unusable. Geda is functional for schematic entry (if you are a unix geek), but is extremely primitive and quite buggy. One thing I'd say I don't like about Altium is having to go through the "execute changes" dialog box every time I make changes to the schematic to having those changes be reflected in the layout. Your Altium project can capture all the information needed to physically realize your PCB in one place, which is quite nice. It can also automatically purchase components at the next price break up if it ends up being cheaper to do so. One click and I have the BOM, component inventory counts, and price per board / 100 boards / etc. Multi-trace routing is sweet.īeing able to link supplier data from Mouser / Digikey / Etc to library parts is priceless. I can get cleaner, more compact trace layouts in less time compared to Eagle. Push-routing and the other numerous routing features are great. If you're designing compact devices where the 3D model of the PCB + components is important, Altium has very good 3D integration. There are many beginner youtube videos and tutorials online for learning Altium, which made it very easy to adopt. I went from Eagle to Altium Designer and couldn't be happier.

Power, electronics, electromagnetics, semiconductors, software engineering, embedded systems - all topics relevant to this field, professional or academic. In the menu bar of the circuit diagram, select PSpice > New Simulation Profile to open a new simulation profile. Next, link the library file (.lib) to the project. Double-click the part to place the symbol on the circuit diagram. Library updates may take up to 48 hours to appear.Discuss anything related to the field of Electrical and Computer Engineering. The added symbol file (.olb) is displayed in the Part List. This site is automatically generated and mirrors the latest library data available on the KiCad GitLab page. This can significantly save on bandwith usage and allows users to control which library versions they use. Even before PSpice had schematic entry I used Orcad to generate the netlists to feed into PSpice. simulation and PCB layout and will import Eagle, Kicad, Altium and LTSpice files. Cloning the library repositories means that users only need to download updates to the libraries, rather than re-downloading library files multiple times. In fact Digikey have number of design tools although some are restricted and not free. Users who wish to keep up to date with the latest libraries should clone the KiCad libraries using Git or SVN. The following library files are available: Library licensing information is available at. If you would like to contribute to the libraries, refer to the library contributing guide at. This site serves the latest KiCad libraries which are community contributed on the KiCad GitLab page.
