During September 2025, Olle contributed to the llvm/circt repository by enhancing the circt-test tool to support granular control over Verilog generation options. By implementing the acceptance and propagation of LoweringOptions, Olle enabled users to specify parameters such as disallowing local variables, directly impacting the determinism and compatibility of generated Verilog with downstream verification backends like SBY. This work, developed in C++ and leveraging expertise in compiler development and SystemVerilog, improved the reproducibility and fidelity of testing workflows. The feature addressed the need for configurable Verilog lowering paths, streamlining continuous integration and aligning outputs with backend requirements.
