Compiling the Circuit Simulator kTechLab

I was searching for a circuit simulator for Linux and found kTechLab.

There is not a built package for Ubuntu (I’m using Ubuntu 16.04) then I compiled it from source code:

$ git clone
$ cd ktechlab/
$ sudo apt-get install libqt4-dev
$ sudo apt-get install kdelibs5-dev
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install

Then I just execute:

$ ktechlab

And kTechLab starts in all its glory!

  1. If you want to keep the installation inside your home directory, I recommend the following (replace ‘marcelo’ by your login account:

    cmake -DCMAKE_INSTALL_PREFIX:PATH=/home/marcelo/bin/ktechlab ..
    make install

  2. kTechLab is new to me. I’ve never been very successful with spice in the past, except for very simple circuits – critical components were always missing from the parts library. How complete is the kTechLab parts library?

  3. Hi Celem, kTechLab is pretty complete. Also basic components and logic blocks are present. The interface is very friendly, but there are some silly BUGs. Please take a look, maybe it will fit your needs.
