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 call

The clearest difference is rating: C Compiler at 4.3 against VHDL Compiler's 2.7. C Compiler also leads on ratings volume (113 vs 7). VHDL Compiler's advantage is review sentiment (100% vs 59%) and iOS requirement (12.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. C Compiler sells 4 in-app purchases, starting at $2.99 per month and VHDL Compiler sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

C Compiler holds the better App Store score, 4.3 against 2.7. That said, the two scores are not equally well evidenced: C Compiler has 113 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 59% of C Compiler's written reviews are positive against 100% of VHDL Compiler's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

C Compiler ships an update every 4 months, VHDL Compiler every 2 months. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
