PROFILE
Ana Mokan
Over five months, Amokan enhanced the tenstorrent/tt-llk repository by expanding API test coverage, improving simulation reliability, and strengthening firmware stability. He developed parameterized test infrastructure in Python and C++ to validate the eltwise unary datacopy API, increasing scenario coverage and reducing regression risk. Amokan addressed hardware synchronization issues by refining TRISC reset handling and mailbox signaling, which stabilized simulation workflows and reduced flaky test outcomes. He also improved data format handling and test automation, ensuring robust cross-architecture support. His work demonstrated depth in embedded systems, low-level programming, and CI/CD, resulting in more maintainable and reliable validation pipelines.

Oct 1, 2025Oct 2025 Monthly Summary for tenstorrent/tt-llk focusing on high-impact fixes, stability improvements, and expanded testing. Delivered targeted bug fixes and strengthened test coverage across TRISC reset handling and data formatting, driving reliability and predictable behavior in firmware. Key outcomes: - Unintended TRISC resets fixed by adjusting the TRISC reset mask to target three TRISCs per chip architecture, improving system stability and uptime across affected hardware variants. - UntilizeGolden data format handling corrected to pass the correct data format argument to the untilize function and expanded pack_untilize tests to cover more combinations, while skipping a problematic Int32 case to preserve destination accumulation correctness. - strengthened test coverage and instrumentation around UntilizeGolden and pack_untilize to reduce regression risk and improve maintainability. - Code changes tied to two committed fixes in the tt-llk repo (fef355e81843ceb311e74616744c4bc115711120; 61bec9e7e49fa12d584f91f5036163568ab648a5), demonstrating robust firmware practices and cross-architecture considerations. Business value and impact: - Enhanced stability reduces maintenance overhead and unplanned downtime in production environments. - More reliable data handling across architectures lowers risk of data corruption and improves diagnostic clarity. - Improved test coverage accelerates future development by catching edge cases earlier and decreasing regression risk. - Evidence of core skills: embedded firmware changes, architecture-aware masking, data formatting, and test automation.

Jul 1, 2025July 2025 — tenstorrent/tt-llk: Delivered simulator testing support and enum cleanup to improve test coverage, reliability, and developer clarity. Implemented simulator execution with CLI options for simulator and port, updated test configurations to enable simulated testing (including disabling arc_msg and adjusting backoff/timeout calculations). Cleaned the DstSync enum by removing deprecated SyncTile16 and SyncTile2 variants to simplify synchronization logic. These changes, backed by two commits, enhance CI stability and reduce configuration risk, accelerating validation of new features.

Jun 1, 2025June 2025 monthly summary for tenstorrent/tt-llk: Implemented critical simulation correctness fixes to improve reliability and test stability. Key changes include BRISC-TRISC synchronization (BRISC reset released before TRISC) and relocation of TRISC kernel running status signaling to device.py to ensure correct mailbox updates after Tensix operations, preventing premature test completion. These changes reduce flaky simulations and improve workflow reliability.
