Integrated Development Environment (IDE) for learning HDL
UMHDL is an educational Integrated Development Environment (IDE) intended for learning digital designing with programmable logic devices using Hardware Description Languages (HDL) through simulation. It is an open-source application created at the Miguel Hernández University (UMH). The aim for the UMHDL development was to have a graphical application that allows learning the VHDL language without licensing restrictions (using some existing open-source tools) and requiring few resources. So, the interface developed acts as a front-end that allows writing code (with syntax highlighting), invokes an external VHDL compiler and simulator (such as GHDL), and displays the result of the simulation graphically as waveforms (invoking to GTKWave).

Make your own virtual FPGA system and profile deeply with CI.
TestDrive Profiling Master is a free simulation software for Verilog/SystemVerilog and C/C++. It supports a CI (Continuous Integration) activity for H/W & S/W engineers' cooperation. Run by MS Windows environment, its use is governed by MIT License(Profiles) and LGPLv3(TestDrive Profiling Master). Based on the powerful compiler Verilator and GCC, TestDrive Profiling Master provides a totally free virtual FPGA system environment with various dynamic documents for profiling in deep on your system design. It performs a seamless conversion to a real FPGA environment without any changes of your testing software. I hope you will accomplish a successful design with TestDrive Profiling Master.

Digital Circuits Design and Simulation
Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. In this software, circuit can easily be converted into a reusable Module. A Module may be used to built more complex circuits like CPU. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display and Digital Oscilloscope etc. provided in the software. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems. In this software, a circuit may be designed using graphical components or may be entered as Sum-of-Product Boolean form.

Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci
