Worked on stabilizing vector operation validation within the pulp-platform/spatz repository, focusing on the Vector Functional Unit (VFU) pipeline. Addressed a validation bug by replacing vsew-based logic with ELEN-based validation for scalar and reduction contexts, which improved the accuracy of microoperations issued by the VFU and reduced invalid operation paths. This change enhanced runtime correctness and resilience of the hardware pipeline, laying the foundation for future ELEN-based improvements. The work involved SystemVerilog for hardware design and digital logic design skills, emphasizing careful validation logic updates to ensure more reliable vector processing in the context of open-source hardware development.
