An integrated circuit (IC) design includes configurable circuits arranged in a mesh structure to facilitate routing of signals between different platforms or logic blocks within the design. Each configurable circuit has a semiconductor element with input and output terminals in a first semiconductor layer, input/output (I/O) ports corresponding to directions of the mesh structure in a second semiconductor layer, configurable input vias to allow a signal traveling in a first direction to be received, and configurable output vias that allow an output signal to be output from the configurable circuit in a second direction.
