In this paper, we present the design of a GALS wrapper used in Network on Chip (NoC) based on standard cells. The GALS wrapper includes two communication ports, 4-phase handshake circuits, data buffer and signal synchronizer. The detailed design methodology of GALS wrapper is given and the circuits are validated with Verilog-HDL and implemented in FPGA. The simulation results show that the wrapper provides fast and reliable asynchronous communication services for the subsystems working with different clocks in NoC.
