2025-08 Monthly work summary: Implemented hardware-aligned vector length optimization for the T1 family. No major bugs reported this period. Reduced VLEN from 4096 to 2048 across T1, T1emu, T1rocketemu, and T1RocketTile TOML configurations (blastoise and uxie). All changes tracked in a single commit to facilitate review and potential rollback if needed.

May 2025 (chipsalliance/t1) — Delivered a critical RTL bus address width fix and expanded metadata extraction for release JSON, delivering improved memory addressing reliability and richer release analytics. Key outcomes include corrected addressing logic using eLen to reflect extended length, preventing misaddressing and improving subsystem interaction, along with future-proofing the metadata pipeline. The work also established groundwork for analytics and tooling through enhanced JSON metadata across multiple components (T1, TestBench, T1RocketTile).

April 2025: Delivered targeted NTT test coverage for the vlen16k configuration in chipsalliance/t1 to validate correctness of the NTT path under high-vector-length scenarios. This strengthens test coverage, reduces risk in performance-critical transforms, and improves CI reliability. No major bugs fixed this month. Overall impact includes higher confidence in NTT correctness, smoother release cycles, and strengthened repository health. Technologies/skills demonstrated include test-driven development, high-length configuration testing, Git-based workflows, NTT validation, and CI-integrated test design.

January 2025 focused on correctness improvements and capability expansion across two repos. Delivered a critical bug fix in chipsalliance/t1 that ensures correct floating-point adder behavior by correcting a permutation reference, and added FIRRTL Layer Convention support in llvm/circt with a new enum and CAPI-ready API to manage layer attributes. These changes improve reliability, enable layer-aware optimizations, and lay groundwork for downstream tooling and interoperability.

December 2024: Focused on stabilizing core infrastructure, unifying module interfaces, and delivering safety-oriented enhancements across Circt, Chisel, and T1. Key outcomes include the rollout of the GeneralOM framework across multiple core components, safer Panama-related APIs, and reliability improvements in builds and documentation. These changes reduce maintenance costs, improve developer productivity, and enable faster, safer feature delivery.

November 2024 monthly summary for chipsalliance/t1 focused on delivering architecture-level improvements and broadening benchmarking coverage. Key features delivered include (1) Memory subsystem naming consistency and VRF/Cache refactor: renaming SRAM instances to descriptive names (dcacheTagSRAM, dcacheDataSRAM), renaming VRF rfVec to vrfSRAM, refactoring VRF SRAM instantiation using Seq.fill, and removing an unused rf variable, improving readability and readiness for physical design handoff. (2) Benchmark configuration expansion and tuning for the T1 architecture: adding and updating TOML configurations with new dLen and vLen profiles (including floating-point variants), enabling rv_m instruction set, and adjusting cacheable and vrfRamType parameters across testbenches to broaden testing scenarios. These changes collectively increase test coverage for performance evaluation and align benchmarks with architectural capabilities. Major bugs fixed and maintainability improvements are reflected in the config and naming cleanup: fixes to rookidee dLen, benchmark config adjustments, and streamlining configuration names to reduce misconfigurations across testbenches. Overall impact: Enhanced reliability and maintainability of the T1 workstream, expanded performance evaluation coverage, and stronger alignment between RTL refactors and benchmarking, enabling faster iteration and safer design handoffs. Technologies/skills demonstrated: RTL/Chisel Verilog refactoring, testbench and TOML configuration management, benchmarking automation, version-control hygiene, and architecture-aware design discipline.
