| الوصف: | In recent years there has been a surge of interest in designing custom accelerators for power-efficient high-performance computing. However, available tools to simulate low-level RTL designs often neglect the target system in which the design will operate. This hinders proper testing and debugging of functionalities, and does not allow co-designing the accelerator to obtain a balanced and efficient architecture. In this paper, we introduce gem5 + rtl, a flexible framework that enables simulation of RTL models inside a full-system software simulator. We present the framework’s functionality that allows easy integration of RTL models on a simulated system-on-chip (SoC) that is able to boot Linux and run complex multi-threaded and multi-programmed workloads. We demonstrate the framework with two relevant use cases that integrate a multi-core SoC with a Performance Monitoring Unit (PMU) and the NVIDIA Deep Learning Accelerator (NVDLA), showcasing how the framework enables testing RTL model features and how it can enable co-design taking into account the entire SoC. This research was supported by the European Union Regional Development Fund within the framework of the ERDF Operational Program of Catalonia 2014-2020 with a grant of 50% of total cost eligible under the DRAC project [001-P- 001723], by the Spanish goverment (grant RTI2018-095094- B-C21 CONSENT), by the Spanish Ministry of Science and Innovation (contracts PID2019-107255GB-C21) and by the Catalan Government (contracts 2017-SGR-1414, 2017-SGR705). This work has also been supported by the European Community’s Horizon 2020 Framework Programme under the Mont-Blanc 2020 and EPI projects (grant agreements n. 779877 and n. 826647); and by the Arm-BSC Center of Excellence.
