About

SchemaHD

This app allows users to draw circuit diagrams for logic circuits, generating Verilog HDL and performing simulations. It simplifies FPGA development by using schematics instead of complex programming languages, offering advanced security and high-performance parallel processing.

Highlights
  • Draw logic circuit diagrams
  • Generate Verilog HDL
  • Perform circuit simulations
  • Touch-based wiring
  • AXI bus interface support
  • JSON import/export
  • Offline network operation

FPGAs can dynamically generate logic circuits by means of configuration bit streams generated by languages such as Verilog and VHDL. The generated logic circuit cannot be changed by communication data. Therefore, it is very safe and cannot be attacked by hacking, which is a problem with CPUs, to execute arbitrary commands. In addition, the generated logic circuits are all running simultaneously, so the highest performance parallel processing is being performed. It can also generate logic circuits using configuration bitstreams at very high speed. Most of the processing that can be done by the CPU can be done by the FPGA alone. With advanced security and the highest performace, FPGAs are the perfect device for the modern age. However, it takes a lot of effort to learn languages such as Verilog and VHDL. There are other methods such as high-level synthesis from C/C++, but they require a lot of adjustments such as #pragma, and do not maximize the capabilities of the FPGA. Schematics, not programming languages, are needed to maximize the capabilities of FPGAs and to further improve developer productivity. Schematics allow you to grasp the whole picture at a glance, and can perfectly represent parallel processing. SchemaHD is to draw a circuit diagram of a logic circuit, and it's possible to do generation of Verilog HDL and a simulation. A made circuit diagram can be used by a different circuit diagram immediately. You can also install wiring easily by touch operation. A concept of interface is adopted as a terminal, so something structured of a AXI bus can also be used. A terminal it's also possible to distinguish sound argument reason, negative logic and characteristic wiring of a clock and a reset by interface, and which is different in interface, they don't seem able to connect, it is. You can input and output as a JSON file, so the made circuit diagram and interface are also capable of cooperation with other application. Verilog HDL generated from a circuit diagram contains a comment of a terminal name and an instance name, so it's capable of the correspondence which is at the time of problem occurrence. A network connection isn't needed, so it's also effective in information leak prevention. A simple simulation is offered in the present, but it's expected to enhance it early.

Verdict

The call

The clearest difference is rating: Termius at 4.7 against SchemaHD's 3.0. Termius also leads on review sentiment (81% vs 50%) and ratings volume (19K vs 2). SchemaHD's advantage is monetization model (free vs freemium) and iOS requirement (14.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Termius sells 4 in-app purchases, starting at $15.00 per month and SchemaHD sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Termius holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Termius has 19K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 81% of Termius's written reviews are positive against 50% of SchemaHD's.

UpkeepUpdate frequency

Termius ships an update fortnightly, SchemaHD every 10 days. The most recent releases landed on October 20, 2026 and October 10, 2026 respectively.
