2026-04 Monthly Summary for pulp-platform/cheshire. Key delivery: Serial Link Version Upgrade and Hardware Interface Enhancement. Implemented a new version of the serial link across the Cheshire repository, updating dependencies and integrating hardware interface improvements to enhance reliability and performance. The principal commit (79a5f5c477241ea515ad5ba1cf55b550382ad950) drove: dependency bumps, new serial_link integration in hardware and Makefile, RDL integration, and parameterization of the serial link. A downstream fix also addressed obsolete serial_link packaging, improving maintainability. Impact: stronger hardware-software coupling, cleaner dependency management, and a more robust foundation for future Cheshire features. Demonstrated cross-team coordination (deps, vip, rdl, pkg) and improvements to build automation and packaging. Technologies/skills demonstrated: hardware-software integration, dependency/version management, build automation (Makefile), packaging and versioning, RDL integration, cross-repo coordination, and release hygiene.

March 2026 highlights focused on delivering a robust, maintainable register interface for Cheshire, strengthening build infra, and tightening dependency management. Key design shifts included migrating from macro-based access to type-safe, SystemRDL-driven interfaces, and automating header generation for safer SW access. The month also emphasized reproducible builds and code quality hygiene to support scalable development and faster iteration cycles.

February 2026 monthly summary: Delivered foundational platform improvements across two repos, focusing on feature delivery and build-system enhancements to boost integration readiness and future development velocity. Major actions include upgrading the CVA6 SDK submodule in Cheshire to the latest commit for new features and fixes, and reorganizing the build configuration in Snitch Cluster to improve clarity and maintainability.

January 2026: Focused reliability improvements in the synthesis/elaboration flow for the pul p-platform/snitch_cluster module, delivering stable builds and groundwork for future optimizations.

December 2025 hardware/FPGA software month focused on stability, performance, and configurability. Delivered dependency stabilization, cache and resource optimizations, and extended AXI-XBAR configurability. Also addressed an elaboration stability issue to improve build determinism. These efforts reduce maintenance burden, improve runtime efficiency, and broaden hardware design flexibility across two repositories.

Concise monthly summary for 2025-11 focused on business value and technical achievements for pulp-platform/snitch_cluster.

May 2025 (2025-05) summary: Implemented 4KiB page-boundary aware ELF preload in the Target Simulator and refactored the serial link preload to split transfers at page boundaries, improving robustness and compatibility when loading large binaries in the simulation environment. This enhances developer experience and reduces load-time failures in large-binary scenarios.

February 2025: Delivered a key refactor of hardware cluster generation in the pulp-platform/snitch_cluster repository, migrating the configuration format from Hjson to JSON5, standardizing configuration file extensions to .json, and tightening template usage and build system references. Core generation semantics were preserved, while maintainability and flexibility were improved to better support future tooling updates.

January 2025 performance summary for pulp-platform development, focusing on delivering GUI usability enhancements, robust default configurations, and foundational boot-time improvements for the snitch cluster. The work emphasizes business value through faster workflows, improved reliability, and scalable boot processes.
