FPGA code to program the shift register in the chip

I designed a contactless current sensor chip that utilizes a magnetic sensing element to detect current flow without requiring direct electrical contact. One of the components within this chip is a programmable shift register. The shift register can be serially loaded with digital data, allowing users to set various operational parameters such as gain settings. Once programmed, the register outputs control signals that adjust internal analog or digital circuitry accordingly.本研究设计的非接触式电流传感芯片（contactless current sensor chip），依托磁传感元件（magnetic sensing element）完成电流检测，无需与被测电路建立直接电气连接。该芯片内置的核心组件之一为可编程移位寄存器（programmable shift register）。该移位寄存器支持串行加载数字数据，使用者可借此配置增益设置等多项运行参数。完成编程后，移位寄存器将输出控制信号，对芯片内部的模拟或数字电路进行针对性调节。
