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.

Verdict
The clearest difference is in-app purchases: RTC Courses at none against VHDL Compiler's 1. RTC Courses also leads on ads (none vs shown). VHDL Compiler's advantage is iOS requirement (12.0 vs 15.6). On price, update cadence and device support there is nothing between them.
