Stephen Tridgell developed a Bazel-based Vivado build integration for the bazelbuild/bazel-central-registry repository, focusing on modularizing FPGA tooling to support scalable, Bazel-driven development. He introduced a Bazel wrapper for Vivado, enabling improved build isolation, reuse, and testability within FPGA workflows. His approach included moving the Vivado wrapper to a central registry for better maintainability and adding configuration scaffolding to support module management and continuous integration validation. Working primarily with Bazel, JSON, and YAML, Stephen’s contributions streamlined the build process and enhanced the project’s architectural modularity, demonstrating depth in both FPGA development and module management within a collaborative environment.
