Ktechlab is described as 'KTechLab is an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its application circuit' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to Ktechlab for a variety of platforms, including Windows, Linux, Mac, Web-based and Flathub apps. The best Ktechlab alternative is Arduino IDE, which is both free and Open Source. Other great apps like Ktechlab are QUCS, Autodesk Tinkercad, LTspice and Proteus PCB design.
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
The Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.
Impossible to use digital circuits more advanced than gates. No way to use microcontroller like KTechLab or long-time simulation as performance of analog simulation of digital circuits (and it can't be changed).
Tinkercad is a super easy-to-use, browser based 3D design tool. With Tinkercad you can create 3D printable items: toys to play with, decoration to light up your home or jewelry to express yourself. You dream it, you can make it!
LTspice IV is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators.
Proteus PCB design combines the schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design.
Software for Simulating Voltage and Currents of a text file net-list of a electronics components such as Resistors, Capacitors, inductors, transisters, Diodes, Voltage and Current Sources, etc.
An open source ecosystem for IoT development. Cross-platform IDE and unified debugger. Remote unit testing and firmware updates.
Qucs-S is a spin-off of the Qucs cross-platform circuit simulator. "S" letter indicates SPICE. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI.
Multisim is industry-standard SPICE simulation and circuit design software for analog, digital, and power electronics in education and research.
Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. Ngspice is part of gEDA project, a full GPL'd suite of Electronic Design Automation tools.
No GUI, requires few hours to formulate a schematic (KTechLab uses this as backend and formulates schematic from user's design).
Simulink® is a block diagram environment for multidomain simulation and Model-Based Design. It supports simulation, automatic code generation, and continuous test and verification of embedded systems.
A virtual simulation environment for electronic circuits with support of digital and analog devices. It also provides virtual instruments and virtual debugging tools.
