The present application discloses a multi-die FPGA implementing a built-in analog circuit using an active silicon connection layer, and relates to the field of FPGA technology. The multi-die FPGA allows multiple small-scale and small-area dies to cascade to achieve large-scale and large-area FPGA products, reducing processing difficulties and improving chip production yields. Meanwhile, due to the existence of the active silicon connection layer, some circuit structures that are difficult to implement within the die and/or occupy a large die area and/or have a low processing requirement can be laid out in the silicon connection layer, solving the existing problems of making these circuit structures directly within the die. Part of the circuit structures can be implemented within the silicon connection layer and the rest in the die, which helps optimize the performance of FPGA products, improve system stability, and reduce system area.
