# Wokwi Custom Chip Makefile
# Generated by wokwi-cli

# Usage:
# make - Build the chip
# make clean - Remove build artifacts
# make wokwi-api.h - Download the Wokwi API header

# Requirements:
# - WASI-SDK (https://github.com/WebAssembly/wasi-sdk)
# - Set WASI_SDK_PATH environment variable or install to ~/.wokwi/wasi-sdk
#
