Worked on the verilog-to-routing/vtr-verilog-to-routing repository to enhance FPGA routing guidance and reliability. Developed a distance-based lookahead feature using C++ that loads and queries cost maps from memory, supporting both CSV and Cap’n Proto formats, and integrated this functionality into the command line interface with improved error handling and documentation. Addressed nondeterminism in the Parallel Router by introducing floating-point tolerance, ensuring consistent routing outcomes. Further improved code maintainability by refactoring the router lookahead’s cost map from a global to a static variable, increasing encapsulation and testability. The work emphasized algorithm implementation, optimization, and robust software engineering practices.

Aug 1, 2025August 2025: Delivered a targeted encapsulation improvement in Router Lookahead for verilog-to-routing. By changing the simple_cost_map from a global to a static variable in router_lookahead_simple.cpp, the change limits visibility and side effects, improving isolation of the lookahead state, testability, and overall stability of routing cost computations. No major bugs fixed this month. This work enhances reliability for downstream routing results and provides a safer foundation for future optimizations.

Jul 1, 2025July 2025 monthly summary for verilog-to-routing/vtr-verilog-to-routing focused on delivering distance-based lookahead capabilities and ensuring deterministic routing outcomes. Highlights include a new SimpleLookahead with memory-based cost-map loading and distance queries, CLI support, and expanded data format interoperability (CSV and Cap'n Proto), along with a fix to guarantee deterministic post-target pruning in the Parallel Router through floating-point tolerance. The work improves routing guidance, debuggability, and reliability, with implications for faster route planning and more predictable performance in parallel execution environments.
