Paolo Galfano focused on stabilizing the DMA crossbar rule generation logic in the pulp-platform/snitch_cluster repository, addressing a subtle hardware reliability issue. He identified that the index variable in the rule generation was being incremented unconditionally, which could cause incorrect DMA routing when the bootrom was disabled. By making the increment conditional on bootrom enablement, Paolo improved the correctness of DMA routing under various configurations. His work, implemented in SystemVerilog and leveraging his expertise in digital and hardware design, reduced the risk of unintended hardware behavior and laid a more robust foundation for future bootrom and aliasing feature development.
