July 2026: Implemented field width support for string format specifiers in ImportVerilog (llvm/circt). The change enables width, alignment, and padding in %s for $display, $write, and $sformatf, improving formatting usability and IEEE compliance in ImportVerilog. The work updates moore.fmt.string handling to carry width/alignment/padding through MooreToCore to sim.fmt.string; the no-width path remains unchanged for literals. Error handling was updated so width-based specs are supported (e.g., $write("%42s", ...)) and tests/errors adjusted. Commit: 21567ec2f3162b1f616e2b487ebd778e7e6acb85.

June 2026 monthly summary for llvm/circt: ImportVerilog improvements focused on correctness of port handling and enhanced simulation testing. Delivered a critical bug fix for port declaration order to prevent moore.verifier failures when interleaving interface-modport outputs with regular outputs, along with a regression test. Introduced command-line input support via test$plusargs and $value$plusargs, including Moore builtin ops and lowering to the core simulation path. These changes improve import reliability, reduce verification churn, and enable more flexible testing workflows.

May 2026 highlights: Targeted correctness fixes and regression enhancements across Circt and Verilator, with a focus on complex HDL elaboration scenarios, regression coverage, and robust type resolution. Demonstrated proficiency in Slang/elaboration behavior, hierarchical name handling, and cross-repo collaboration to deliver stable, business-ready changes.

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.

June 2025 highlights for pulp-platform/picobello focused on strengthening hardware-software integration and improving port safety in hardware tiles. The team progressed SystemRDL address map integration into the build, and completed a targeted network-interface port cleanup to reduce wiring risk and improve verifiability.

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)".
