Worked on the tenstorrent/tt-exalens repository over four months, delivering features that enhanced debugging, test coverage, and build reliability for embedded systems. Developed a unified search utility across multiple modules, improved register inspection for the Wormhole architecture, and enabled hardware-based code coverage using GCov. Modernized the build system by introducing distinct debug and release configurations, updating Makefiles and CMakeLists.txt, and refining CI workflows. Leveraged C++, Python, and CMake to implement modular refactoring, extend unit testing, and optimize kernel binaries. These efforts improved observability, streamlined hardware testing, and accelerated development cycles, resulting in more robust and maintainable system integration workflows.

Aug 1, 2025August 2025 monthly summary focusing on hardware-ported Code Coverage (GCov) enablement for tt-exalens. Ported code coverage instrumentation to hardware, enabling robust test coverage on real devices. Updated build system to produce debug, release, and coverage binaries; implemented linker script changes; extended library tests; applied micro-optimizations for kernel binaries; fixed a minor callstack bug. These efforts improve observability, debugging efficiency, and overall product quality. Business impact: faster defect root-cause analysis, higher confidence in code coverage, and streamlined hardware testing workflows.

Jun 1, 2025June 2025 for tenstorrent/tt-exalens focused on cross-tool usability, stability, and test coverage. Key deliverables include a unified search utility across noc, debug-bus, and tensix-reg with a shared core and new unit tests; a robust Blackhole architecture PC read path with routing to blackhole_read_pc and simplified tests; and expanded NOC test coverage validating NOC0/NOC1 writes and transaction counters. These efforts improve debugging efficiency, cross-module data accessibility, and overall stability, enabling faster fault isolation and more reliable performance across the toolchain. Demonstrated skills include modular refactor design, cross-repo feature integration, architecture-aware fixes, and rigorous unit testing.
