PROFILE
Stefan Rauch
Worked on the bel_projects repository, delivering hardware and firmware enhancements for embedded and FPGA-based systems. Over four months, contributed features such as power management integration, multi-core firmware initialization, and PCIe transceiver voltage configuration, using C, VHDL, and Makefile. Addressed hardware-software alignment by updating build systems and hardware description files, ensuring reliable startup and compliance with specifications like the ASMI core manual. Fixed configuration issues, such as aligning PLL frequencies and improving memory map robustness, to reduce deployment risk. The work demonstrated depth in embedded systems, FPGA development, and hardware design, focusing on maintainability and scalable, standards-compliant solutions.

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.
