PROFILE
Fabio Cappellini
Fabio Cappellini contributed to the EPFL-LAP/dynamatic repository by developing three core features over three months, focusing on compiler and hardware modeling enhancements. He implemented the NDWire operation in the Handshake dialect, introducing token propagation control with Verilog and VHDL models to improve hardware synthesis and verification. Fabio also designed the InitOp for single-slot buffers, enabling deterministic initialization and configurable hardware mappings. Additionally, he automated equivalence checking by updating CMake build scripts to fetch external tools like NuSMV and dot2smv. His work demonstrated depth in C++ development, build systems, and hardware description languages, addressing reproducibility and synthesis challenges.

May 1, 2025May 2025: Delivered a foundational capability for robust equivalence checking in the Dynamatic project by enabling external binary dependencies and updating the build pipeline. Implemented automatic download and use of NuSMV and dot2smv, with CMake/build scripts updated to fetch these tools for ElasticMiter. The change improves automation, reproducibility, and accuracy of equivalence checks across releases, reducing manual setup and enabling faster validation.

Mar 1, 2025March 2025 — EPFL-LAP/dynamatic: Implemented a targeted enhancement to the Handshake dialect by adding a new InitOp for single-slot buffers with an initial token. This enables deterministic initial state, supports specific rewrites, and allows configuring the initial token value via INIT_TOKEN in hw.parameters. The change is defined in HandshakeOps.td and implemented in HandshakeOps.cpp, with the commit 926449bdbb9a723e846c9ba125fb05db826b5f0d. Business impact: improves buffer management efficiency and configurability in hardware synthesis flows, reducing manual intervention and enabling more predictable hardware mappings. Technical achievements: MLIR/Handshake dialect design, C++ implementation, dialect ops, and traceable commits.

Feb 1, 2025February 2025: Delivered the NDWire feature in the Handshake dialect with token propagation control, including both sleeping and running state transitions, and corresponding Verilog/VHDL models (dataless and parameterized). Updated Handshake dialect and HW conversion to support NDWire, enabling accurate hardware synthesis and verification. This work strengthens synchronization primitives and hardware modeling capabilities in dynamatic.
