PROFILE
Fabio Cappellini
Contributed to the EPFL-LAP/dynamatic repository by developing three core features over three months, focusing on compiler and hardware synthesis workflows. Delivered the NDWire operation in the Handshake dialect, enabling token propagation control with Verilog and VHDL models for accurate hardware representation. Enhanced buffer management by implementing an InitOp for single-slot buffers, allowing deterministic initialization and configurable token values through dialect and C++ updates. Improved build automation and reproducibility by integrating external binary dependencies for equivalence checking, updating CMake and scripting to fetch and utilize NuSMV and dot2smv. Demonstrated depth in compiler development, build systems, and hardware description languages.

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.
