PROFILE
Stefan Rauch
Sebastian Rauch contributed to the GSI-CS-CO/bel_projects repository by developing and refining hardware control features for embedded and FPGA-based systems. Over four months, he implemented power management integration, multi-core firmware initialization, and hardware-level voltage configuration, using C, VHDL, and Makefile to bridge software and hardware layers. His work included aligning system PLL frequencies to ASMI specifications and improving build robustness for memory mapping. By addressing both feature development and bug fixes, Sebastian ensured safer power sequencing, scalable multi-core support, and reliable PCIe transceiver operation, demonstrating depth in embedded systems, FPGA development, and hardware configuration throughout the project lifecycle.

Jul 1, 2025In 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.

Apr 1, 2025April 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.
