OpenCircuitX is a free, open-source EDA (Electronic Design Automation) platform
for VHDL and Verilog: the hardware description languages (HDL) used to design
digital logic. It is developed by OpenLabX and unifies an IDE-quality
HDL editor, a visual circuit canvas, an RTL schematic viewer, a
waveform viewer, and a full FPGA toolchain in one window, for hardware
engineers, students, and FPGA hobbyists alike.
