Description
The TomatoCube iCE40LP384 HollowClock IDE is a lightweight, cross-platform desktop application for writing, managing, and compiling Verilog HDL projects targeting the TomatoCube iCE40LP384 HollowClock FPGA Development Board.
Built around the APIO toolchain, a Python-based command-line tool that simplifies FPGA development by integrating the open-source iCE40 toolchain, allowing users to compile and prepare their Verilog designs for deployment to the FPGA board.

Technical Information
——————————————————————
The TomatoCube iCE40LP384 HollowClock Development Board is powered by the Lattice iCE40LP384 FPGA, a compact, low-power device featuring 384 Look-Up Tables (LUTs).
The board is designed as an accessible platform for learning digital logic, FPGA development, and Verilog HDL (Hardware Description Language) – a language widely used in the semiconductor industry to design and describe digital circuits.
