Over a three-month period, this developer contributed to the pulp-platform repositories by delivering four hardware features focused on embedded systems and FPGA development. Their work included implementing a DRAM serial link interface for the Cheshire Tile in SystemVerilog, integrating SystemRDL-based address map generation into the build process, and modernizing register description workflows in snitch_cluster by migrating from Hjson/reggen to RDL/peakrdl. They updated build systems and CI pipelines using Makefile and YAML, improved hardware-software integration, and enhanced port safety and reproducibility. Their technical approach emphasized robust toolchain integration, maintainable RTL design, and consistent hardware-software interface generation across multiple repositories.
2025-07 Monthly summary for pulp-platform/snitch_cluster: Key feature delivered is the migration and modernization of the register description toolchain. We replaced Hjson/reggen with RDL/peakrdl to standardize register descriptions and strengthen the hardware-software interface generation, with cascading improvements to CI workflows, build scripts, and peripheral register definitions. Commit 201bba33a8a4937aaef122e7f2c02357a82b3826 documents the change. No major bugs fixed this month. Overall impact: more robust, scalable register models; improved CI reliability and maintainability; faster onboarding for new peripherals and features. Technologies/skills demonstrated: RDL, peakrdl, removal of Hjson/reggen, toolchain modernization, CI/build tooling, peripheral register modeling.

Month: 2025-05. Delivered a DRAM Serial Link Interface for the Cheshire Tile within the pulp-platform/picobello repository, establishing the foundation for enhanced DRAM communication and system integration. Key activities included updating the build system to reference the picobello-pd submodule commit and extending the Cheshire tile (cheshire_tile.sv) with the necessary ports and logic for the DRAM serial link, while configuring picobello_pkg.sv to integrate the new interface with the system. The work is captured in commit 5ba3de6d5dd6850491332ccbd419a906066bd700 with message: "Add additional serial link for dram (#33)".
