Monthly work summary for 2025-08 focusing on delivering features and stabilizing the bedrock-rtl stack. Key contributions include modularizing ECCGen, hardening encapsulation for simulation/FPV targets, and aligning mock synthesis behavior with the production path. These efforts improve maintainability, reduce external usage risk, and ensure consistent artifacts across CI/builds.

July 2025: Delivered Flow Serializer consistency and validation improvements and reinforced BR simulation/assertion reliability in bedrock-rtl. Key activities included aligning the serializer with the deserializer, integrating a validation module, updating the build with a new dependency, and fixing simulation race conditions and assertion paths to improve reliability and data integrity.

May 2025: xlsynth/bedrock-rtl – Bug fixes improving toolchain compatibility and arbiter robustness; no new features delivered this month.

April 2025 monthly summary for xlsynth repositories (xlsynth-crate and bedrock-rtl). Focus was cross-platform release tooling reliability, dependency management, ECC reliability, and CI automation. Delivered macOS arm64 support and expanded binaries in download_release; centralized dependencies; corrected SECDED ECC decoder logic and expanded tests; improved ECC code generation with automatic ParityWidth derivation and packaging; and significantly enhanced Nightly JasperGold FPV CI with broader test coverage, sampling, timeouts, and logging. These efforts reduce release friction, improve build/test quality, and enable more robust validation of designs across platforms.

March 2025 monthly summary for xlsynth/bedrock-rtl: Delivered a robust CI/CD overhaul with Bazel and Verilog testing integrated into GitHub Actions, established granular CI jobs for Verilog tooling, and added iverilog and VCS test coverage to raise build quality and feedback granularity. Implemented a reproducible development/CI environment via a Rocky Linux 8-based Docker base image with comprehensive build-time dependencies and EDA tools. Improved FPV elaboration reliability by updating build configs, setting a default DataWidth for ECC modules, and adding a custom TCL header for elaboration tests, significantly reducing flaky outcomes. Enhanced project documentation and status visibility with verilog rules edits and dynamic CI/test badges, improving onboarding and stakeholder communication.

February 2025 monthly summary for xlsynth/bedrock-rtl: Delivered core stability fixes across runtime, TB elaboration, and plugin paths; implemented and verified br_ram_initializer; implemented tooling and environment improvements with Dockerfiles for IVerilog/Yosys and per-tool license resource tuning; and updated verification/CI workflows to improve reliability. Business value includes more robust simulations, fewer flaky builds, and faster feature validation, enabling more reliable hardware development and faster iteration cycles.

January 2025 focused on strengthening correctness, testability, and toolchain reliability in xlsynth/bedrock-rtl. Delivered macro-driven validation, stabilized elaboration, improved verilog/test tooling, extended ChipStack coverage, and hardened security and maintenance posture across the RTL stack. The work improves data integrity checks, CI reliability, and developer productivity, while keeping the codebase maintainable and aligned with FPV/test standards.

December 2024 performance summary for xlsynth/bedrock-rtl: delivered substantial hardware-RTL improvements across RAM emulation, ECC reliability, build infra, and data-path flexibility. The work accelerates simulation speed, enhances fault-tolerance, and strengthens CI/deployment. Key outcomes include faster testbenches via a mock flop-RAM, improved ECC decoding and testing, robust CI by way of Docker/Bazel tooling updates and relaxed Verilog constraints, and cross-width data transfer with br_flow serializer/deserializer.

November 2024 highlights for bedrock-rtl (xlsynth/bedrock-rtl): Strengthened verification infrastructure, expanded data-path capabilities, and standardized tooling/documentation to accelerate delivery and reduce maintenance burden. Key outcomes include Bazel FPV/test infrastructure improvements for br_delay and br_delay_nr, enhanced verilog test macros with no-sandbox support and an optional tool argument for Bazel rules, and a suite of macro refactors to reduce churn. Major features and improvements delivered: - Data-path and RAM: added br_ram_addr_decoder, br_ram_flops_1r1w, br_ram_data_rd_pipe (renamed br_ram_flops_1r1w_tile); implemented br_mux_bin; added demuxes br_demux_onehot and br_demux_bin; introduced a simulation unit test for br_ram_flops_1r1w. - Sandbox, lint, and policy: sandbox rules (rule_verilog_sandbox) and fixes; verilog_lint policy; runfiles and Bazel RC/lint hygiene. - Macro and assertion hygiene: implemented BR_ASSUME macro; enhanced BR_ASSERT_STATIC/logging; expanded BR_ASSERT_COMB usage and BR_ENABLE_ASSERT_COMB guard. - Cleanup and maintainability: tie-off macro cleanup; cleanup of BR_UNUSED_NAMED/BR_UNUSED_TODO; alignment with BR_TIEOFF macros. - Documentation and standards: README overhaul; Bazel docs and standardization (rename BAZEL_VERILOG_TEST_TOOL to BAZEL_VERILOG_RUNNER_TOOL); namespace packaging for PyPI; Plugin API version declaration; updated parity codes/readme and tooling docs. Overall impact and business value: faster, more reliable verification cycles; cleaner, more maintainable macro/data-path code; expanded hardware features and better onboarding through improved docs and tooling. Demonstrated technologies: Bazel FPV, Verilog test macros, sandboxing, macros and assertion framework, RAM/data-path modules, test simulations, and Python-based tooling/packaging."

2024-10 (xlsynth/bedrock-rtl) focused on reliability, onboarding, and workflow cleanliness. Fixed FPV test flakiness by updating tool identifiers in BUILD.bazel, expanded developer onboarding with Bazel Verilog usage guides and integration docs, and reduced commit noise by excluding generated Verilog rules from pre-commit formatting. These actions improved test stability, accelerated contributor onboarding, and improved CI/build hygiene.
