Designing and Building Modern Modular SoCs w/ Open Source Federation Tools
summary
Federation tools bundle three open-source utilities for modular SoC construction and reproducible onboarding: wit, do, wake. The flow uses Docker, wit to resolve ~20–25 git repos, do to produce a JSON5 IP manifest and generate Scala wrappers, and wake to orchestrate builds and caching. The example onboards a simple PIO + VIP loopback peripheral into a Rocket-based test-socket, compiles drivers, runs a RISC‑V C test that writes then reads the device, and the simulation-based test completes successfully.
