Write VHDL code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! VHDL (VHSIC Hardware Description Language) is a hardware description language used in electronic design automation to describe digital and mixed-signal systems such as field-programmable gate arrays and integrated circuits. VHDL can also be used as a general purpose parallel programming language. This app uses the open-source GHDL simulator (http://ghdl.free.fr). GHDL is a VHDL compiler that can execute (nearly) any VHDL program. GHDL is not a synthesis tool: you cannot create a netlist with GHDL (yet). Features: - Compile and run your program - View program output or detailed error - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting and line numbers - Open, save, import and share VHDL files. Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - One file can be run at a time - All entities should be have the same name as their files.
