Abstract Transmission line (TL) Parameter Identification (PI) method plays an essential role in the transmission system. The existing PI methods usually have two limitations: (1) These methods only model for single TL, and can not consider the topology connection of multiple branches for simultaneous identification. (2) Transient bad data is ignored by methods, and the random selection of terminal section data may cause the distortion of PI and have serious consequences. Therefore, a multi-task PI model considering multiple TLs’ spatial constraints and massive electrical section data is proposed in this paper. The Graph Attention Network module is used to draw a… More > Graphic Abstract

Abstract Interconnected cells, Configurable Logic Blocks (CLBs), and input/output (I/O) pads are all present in every Field Programmable Gate Array (FPGA) structure. The interconnects are formed by the physical paths for connecting the blocks . The combinational and sequential circuits are used in the logic blocks to execute logical functions. The FPGA includes two different tests called interconnect testing and logical testing. Instead of using an additional circuitry, the Built-in-Self-Test (BIST) logic is coded into an FPGA, which is then reconfigured to perform its specific operation after the testing is completed. As a result, additional test circuits for the FPGA board… More >
