PROFILE
Eric Dubberstein
Eric Dubberstein developed core automation and parser tooling for the tathagatasrimani/codesign repository, focusing on C and Verilog code transformation and design analysis. He built a Python-based parser leveraging clang to replace C operators and variables with C-Core abstractions, improving operator handling and variable safety. Eric enhanced Verilog and SystemVerilog parser robustness, refactoring grammar and state machines to support complex constructs and benchmarks. He introduced YAML-driven configuration for technology parameters, enabling accurate 130nm process modeling and automated design exploration. His work demonstrated depth in AST parsing, compiler internals, and hardware description languages, resulting in improved maintainability and simulation fidelity.

Feb 1, 2025February 2025: Delivered foundational C-Core automation in codesign. Implemented a Python-based parser (clang) to replace standard C operators and variables with C-Core function calls, and added a header defining C-Core components including a Register class. This enables consistent operator handling, safer variable management, and easier future instrumentation. No critical bugs fixed this month; focus on stabilization and enabling future features.
