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).


  • Currently support several VHDL compilers: GHDL, FreeHDL, and nvc.
  • Templates for new VHDL files (main module and test bench).
  • Support for Verilog is planned with some free compiler.
  • Multi-language: the user can choose the IDE language: Spanish, English, Ukrainian, Arab, French, Chinese, Gallego, Valenciano, Russian, ...
  • Multi-platform: UMHDL has been developed in Java, and compiled to native executables using ExcelsiorJet; it has been tested in Windows (32/64-bit), Linux (32/64-bit) and Mac OS X.
  • Small footprint.
