PROFILE

Stefan Rauch

Sebastian Rauch contributed to the GSI-CS-CO/bel_projects repository, focusing on embedded systems and FPGA development using C, VHDL, and Makefile. Over four months, he implemented hardware control features such as ComExpress power button integration and multi-core firmware initialization, improving power management and startup reliability. He enhanced build robustness by refining memory map handling and addressed hardware configuration by aligning SYS_PLL4 output frequencies to ASMI core specifications. Sebastian also configured GXB transceiver voltages for PCIe, ensuring signal integrity. His work demonstrated depth in hardware-software integration, addressing both feature development and critical bug fixes across firmware, build systems, and hardware design.

Work History

Jul 1, 2025

In July 2025, delivered a focused hardware alignment fix in bel_projects to ensure SYS_PLL4 outputs comply with the ASMI core spec. The change aligns the sys_pll4 output with the documented frequency (25MHz) per ASMI core manual 18.1, replacing the previous 50MHz setting. The work involved a VHDL update in monster.vhd and a targeted commit (cb871d4a1c1cf307aff7ee4dd6703c5df8e7482f) applying the ASMI-aligned frequency change. This fix reduces configuration drift, mitigates production risk, and streamlines integration with the ASMI standard for future hardware deployments.

April 2025 monthly summary for bel_projects: Implemented FG Firmware Enablement and Multi-Core Initialization and improved build robustness for SCU4SLIM. The FG feature re-enabled firmware with a 2-core initialization path, updated Makefile (SHARED_SIZE, USRCPUCLK, PATHSCU), added fg.c, and adjusted VHDL to support two cores and updated init file naming. The SCU4SLIM fix ensures the correct shared memory header is used, preventing build/runtime errors. These changes reduce deployment risk, improve startup performance, and lay groundwork for future multi-core scalability.
