PROFILE
Philippe Sauter
Philipp Sauter contributed to the pulp-platform/croc repository by developing and integrating hardware features such as GPIO and UART peripherals, modernizing build and CI/CD workflows, and enhancing documentation for maintainability. He migrated the UART interface from APB to OBI, updated drivers, and implemented loopback testing to improve hardware-software integration and validation. Using SystemVerilog, Verilog, and Python scripting, he refactored build systems to adopt yosys-slang, streamlined simulation and synthesis flows, and improved artifact handling in CI. His work addressed both hardware and software reliability, reduced onboarding time, and enabled reproducible builds, reflecting a deep understanding of digital design and automation.

May 1, 2025May 2025 monthly summary for pulp-platform/croc: Key features delivered include initial parasitic extraction in the OpenROAD flow with a new rule file and build integration, and the OBI interconnect update (new obi_cut module and refinements to components like obi_atop_resolver and obi_demux). Also refreshed the Common Cells library to v1.38.0 and updated the Verilog assertion framework; added documentation and tooling enhancements for ETHZ icdesign and the 1.1 release notes with an SRAM timing fix. Major bugs fixed include CI artifact path correction in GitHub Actions, LVS netlist simplification by excluding filler cells and bondpads, and configurable A_DLY SRAM pin via soc_ctrl; plus removal of the unused PERIOD_PS variable across Tcl scripts and Makefiles. Overall impact includes improved build reliability and artifact handling, more accurate parasitic/timing analysis, streamlined LVS checks, and clearer tooling for external users. Technologies demonstrated encompass OpenROAD, OBI, Verilog, TCL, Yosys, build automation, CI/CD, and comprehensive documentation practices.
