Worked on the llvm/circt repository to address a critical issue in the FIRRTL lowering pipeline, focusing on attribute preservation during the conversion from WireOp to NodeOp. Using C++ and leveraging compiler design principles, implemented a fix that ensures sv.attributes, such as mark_debug, are correctly copied and retained for downstream processing. This change prevents silent loss of debugging and synthesis attributes prior to LowerToHW, improving consistency and reducing downstream rework. The solution involved modifying EliminateWires behavior and aligning conversion patterns with existing hardware description language workflows, demonstrating attention to detail in attribute handling and robustness in the lowering process.
