Monthly work summary for 2025-09 focusing on verification and testing framework enhancements for Chips Alliance I3C core, with expanded coverage, multiclock simulation support, and improved RSTACT testing to reduce silicon risk and accelerate validation.

Month: 2025-05 — Focused on stabilizing and modernizing the dependency chain for chipsalliance/i3c-core by upgrading PeakRDL-Cocotb to be sourced directly from GitHub. This change removes the local copy, centralizes dependency management, and updates requirements to reference the GitHub source, enabling smoother updates and consistent environments across development, CI, and production. No major bugs were reported or fixed this month; the primary emphasis was on reliability, maintainability, and faster future iteration of testbench tooling. This work reduces maintenance overhead and positions the project for more rapid integration of upstream improvements.

April 2025 monthly summary: Delivered naming consistency across VeeR design artifacts and aligned tests with updated recovery sequence requirements. Key changes include: (1) Consistent Prefixing of Design Filenames with VeeR Macros in chipsalliance/Cores-VeeR-EL2; (2) Caliptra Recovery Sequence compliance in i3c-core, including Indirect FIFO Max Transfer Size reset to 0x40 and removal of write enable to enforce read-only; (3) Test adjustments to reflect new behavior by excluding a bypass CSR from CSR access tests and extending recovery test timeouts. These changes improve artifact traceability, spec conformance, and test resilience, reducing maintenance costs and risk in production.
