Logisim useful for professional design work...

I used Logisim years ago, and what made it useful was it would allow you to program in the propagation delay in the gates to more closely simulate a real system.  At the time I bought a copy with manual for $30 (now about 8 years ago).  Nice to see the tool is still around ( and likely updated).

This is really a very nice open source initiative, thanks for sharing valuable information.

One more for your consideration: SIGROK signal analyzer. Sigrok is an analysis engine with PulseView doing the GUI. Sigrok uses over a dozen front ends, from the built-in sound cards reading analog signal at 20kHz up to 192 kHz in some cases, to dedicated hardware GPIO boards such as the cheap $8 EZ-USB boards (16 digital I/Os at 24 MHz).

Significantly, Sigrok has many protocol decoders (I2C, I2S, SPI, USB, EDID, CAN...) and can even stack decoders (decoding accelerometer protocol wrapped in i2c datastream).


In terms of flexibility for protocol analysis, sigrok actually looks nicer than the analysis packages on commercial scopes that I've tried.

Thanks a lot for bringing the collection of very nice and cool Free list of simulators many of them were not know to me, but now I will try many of them and will promote them as well. 

I would like to recommend the users the site http://www.osalt.com/, at any time if you are in need of a paid software but do not want to spend you can look for the open source alternative on this site.

SmartPhone Support and Explanation will Make Those Tools More Beneficial

I was looking Calculatoredge. This is indeed a good tool for high school and engineering students. But it will be more helpful if these tools can be ported in SmartPhone (like an andriod app). Also besides calculation if it can explain the logic behind the calculation then it will be great.

May be the above two will be applicable for the other tools also

Regards,

Barun

Re : Top Free DIY Tools Every EE Needs

I am a fun of free DIY tools and I am aware of several tools that are helpful and can be found for free. Nowadays there are many useless tools available on net and will not help you at all. They may be useless in the sense that they cannot posses the feature you are looking forward to use at that time. Some tools are worthy and are very effective. I think when designing a DIY tool, before you post it on net for free, you should make sure that it is perfect and can help in as many ways as possible.

Another suggestion for schematic capture, simulation and PCB design

EasyEDA is a free web-based EDA tool. It's still under heavy development and has a few rough edges but is pretty powerful stuff. It's quite unusual too because although it offers a very low cost PCB service, there's no tie-in them: users can  download Gerbers and have their PCBs made by any supplier.

Re: need a verilog simulator

There's a very simple text based simulator here: http://iverilog.com/

It has a sister site for netlist based ngspice simulation at: http://ngspice.com/

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
