  @article{steiner2025splitncover, abstract = {The development of safe hardware is currently a major concern in the automotive industry. Due to the high computational and memory requirements of advanced driver-assistance systems and autonomous driving, consumer hardware such as LPDDR DRAM is being deployed in safety-critical areas. Parts 5 and 11 of ISO 26262 define procedures and methods for the development of hardware to achieve a specific Automotive Safety Integrity Level (ASIL). However, consumer devices like LPDDR DRAMs were not originally intended for use in these applications, so they only achieve low ASILs. Additional safety measures can still be added at system level, but this often comes at the cost of reduced performance. In this paper, we present a novel methodology that combines the hardware metrics analysis of ISO 26262 with SystemC-based virtual prototyping. This enables the analysis of a system both from the safety as well as from the performance perspective using the same simulation setup. To show the applicability of this methodology, we model an LPDDR5 memory subsystem of a current state-of-the-art ADAS platform and evaluate both the ASIL as well as the performance impact of the safety measures. The new methodology is fully implemented in SystemC and provided as open-source.}, author = {Steiner, Lukas and Kraft, Kira and Christ, Derek and Uecker, Denis and Malek, Christian and Jung, Matthias and Wehn, Norbert}, journal = {International Journal of Parallel Programming}, keywords = {safety}, number = 3, title = {Split’n’Cover: ISO 26262 Hardware Safety Analysis with SystemC}, volume = 53, year = 2025 }

  @inproceedings{10.1145/3695794.3695797, abstract = {Data-driven applications are increasingly central to our information technology society, propelled by AI techniques reshaping various sectors of our economy. Despite their transformative potential, these applications demand immense data processing, leading to significant energy consumption primarily in communication and data storage rather than computation. The concept of processing-in-memory (PIM) offers a solution by processing data within memory, reducing energy overheads associated with data transfer. PIM has been an enduring idea, with recent advancements in DRAM test chips integrating PIM functionality, indicating potential market adoption.This paper introduces a virtual prototype of Samsung’s PIM-HBM architecture, leveraging open-source tools like gem5 and DRAMSys, along with a custom Rust software library facilitating easy utilization of PIM functionality. Key contributions include the first gem5 based full-system simulation of PIM-HBM, experimental validation of the virtual platform with benchmarks, and the development of a Rust library enabling PIM functionality at the software level. Our benchmarks evaluated speedup for PIM in the range of 6.0 \texttimes{}  to  17.5 \texttimes{} compared to a respective non-PIM system for different memory-bound workloads.}, address = {New York, NY, USA}, author = {Christ, Derek and Steiner, Lukas and Jung, Matthias and Wehn, Norbert}, booktitle = {Proceedings of the International Symposium on Memory Systems}, keywords = {myown}, pages = {26–33}, publisher = {Association for Computing Machinery}, series = {MEMSYS '24}, title = {PIMSys: A Virtual Prototype for Processing in Memory}, year = 2024 }
