A developer has documented the complete process of designing a calculator on a field‑programmable gate array (FPGA) from the ground up, sharing schematics, code and testing results on a public forum.

What Happened

The project, posted on a technology news aggregator, outlines how the author selected an FPGA development board, wrote hardware description language (HDL) code to implement arithmetic logic, and integrated a simple keypad and display interface. The author provides links to the source repository, describes debugging steps, and reports that the calculator functions as intended for basic operations.
