The invention discloses a programmable chip for realizing user design by using a rewiring layer, and relates to a programmable chip technology, and the programmable chip is obtained by packaging a bare chip and the rewiring layer. Input and output ports of the bare chip can be connected to corresponding pins on the lower surface of the rewiring layer through top metal wires in the rewiring layer so as to adapt to advanced packaging requirements; the programmable function modules in the bare chip or the programmable function modules and the input and output ports can be connected through a winding framework arranged in the bare chip and can also be connected through a signal leading-out hole and a top-layer metal wire, and a signal transmission path can be constructed by means of the top-layer metal wire in a rewiring layer. The route construction mode is flexible, and the conventional wiring mode is expanded, so that the development and design difficulty is reduced, the wiring difficulty in the bare chip can
