Neutron-Induced SEEs in the Xilinx Versal Prime

Abstract

Results from neutron testing of the Xilinx Versal Prime adaptive compute acceleration platform (ACAP) are presented. The Xilinx Versal is an adaptive computing platform that is designed to do high-speed artificial intelligence calculations, which could be useful for deployed digital and image processing systems that need higher performance computing than radiation-hardened microprocessors but do not want to create a full field-programmable gate array (FPGA) design. The Versal VMK180 evaluation board was irradiated in August 2021 at LANSCE in the ICE House II flight path. This test shows that the FinFET transistors used in the Versal Prime are 10-1000 less sensitive to SEUs than other microprocessors, due to the 7 nm FintFET transistors and the use of error correcting codes. The SEFI sensitivity remains predominantly unchanged from previous generation parts.
