PROFILE
Xander Chin
Developed and stabilized the SWEmuleChip feature for the tenstorrent/tt-umd repository, enabling host-side software emulation of chip hardware for kernel program testing without physical devices. Leveraged C++ for both feature development and bug fixes, implementing memory-backed I/O and stubbing hardware operations to support seamless integration with tt-metal. Enhanced continuous integration workflows by introducing dedicated CI jobs and conditional build guards, ensuring robust validation of the emulation path. Addressed DRAM correctness by resolving memory routing and 64-bit address handling issues, improving test reliability and preparing for broader integration. Demonstrated depth in embedded systems, hardware abstraction, and software emulation throughout the project.

Jun 1, 2026June 2026 focused on DRAM correctness in SWEmuleChip for tenstorrent/tt-umd. Implemented two independent fixes addressing Blackhole/Whitehole memory routing and 64-bit address handling in l1_ptr. The changes stabilize DRAM core lookups and prevent address truncation, advancing reliability and preparing for tt-emule#41 integration. Commit 03c184227d78e00e08a41c0fb192dadf2ee620fc documents Fix 1; Fix 2 depends on widening Core::l1_ptr to uint64_t. Local verifications against pinned SHAs show meaningful improvements and the work is ready for review with CI validation to follow.

May 1, 2026May 2026 monthly summary for tenstorrent/tt-umd focused on stabilizing the UMD emulator integration and enhancing CI validation for the emulation path. Implemented a fix to ensure the SWEmuleChip header is consistently compiled when the emulation path is enabled, guarded the usage to avoid breakages in non-emulation builds, and introduced a dedicated CI workflow to validate the emulation path in parallel with the main device build. These changes reduce PR check fragility, accelerate end-to-end validation of tt-emule with UMD, and strengthen cross-repo integration between the UMD library and the emulation stack.
