Over a three-month period, Scheremo contributed to the llvm/circt and pulp-platform/snitch_cluster repositories, focusing on hardware modeling and developer tooling. He enhanced Verilog and Moore dialect support by implementing runtime features, assertion translation, and robust import flows using C++ and MLIR. His work included refactoring the Verilog LSP infrastructure for improved indexing and reliability, as well as addressing edge cases in Verilog import and function capture. In snitch_cluster, he fixed DMA Crossbar rule ordering to ensure correct memory access sequencing. Scheremo’s contributions demonstrated depth in AST manipulation, IR transformation, and hardware description languages, resulting in more reliable toolchains.
