PROJECT TITLE :

An FPGA-Based Transient Error Simulator for Resilient Circuit and System Design and Evaluation

ABSTRACT:

Error detection and correction (EDAC) has become a lot of necessary with continued device scaling. We propose a field-programmable gate array (FPGA)-based simulator to accelerate the transient simulation of pipeline-level EDAC circuits and their interactions with circuits under test (CUTs). The simulator incorporates the CUT delay profile, the CUT error profile, and the EDAC model. The FPGA-primarily based simulator captures the fine-grained interactions between the CUT and EDAC for the evaluation of the effectiveness of EDAC and its tuning. The simulator is built primarily based on parameterized models, making it general purpose and widely applicable. We demonstrate the capability of this simulator in the evaluation of 2 common pipeline-level EDAC styles, i.e., preedge EDAC and postedge EDAC, using synthesized processors that operate beneath generic error and noise models. The proposed error simulator uncovers key insights to assist guide EDAC styles.
