This paper builds a system based on FPGA, which is used for USB 2.0 data monitor, simulate and verify system. To build the system, and construction of hardware experimental platforms and logical module programming with HDL are both required. The core of the system is FPGA and ULPI peripherals, which extend two external USB ports for FPGA. By using HDL to package ULPI core, generate data buffer and relays module, and build the connection between ULPI data transceiver. And the function of data monitor and collection will be accomplished. The cooperation simulations by using ISE and ModelSim is using for system analyzation, modification, and verification.
