A data acquisition, based on FPGA, was designed by programming with QuartusII simulation software and the function of validation. The system was analyzed deeply by adopting the method of the state machine. A data acquisition structure was designed in the system, which was achieved by designing inputs, analysis and synthesis, simulation and validation and so on. In the process of design inputs, the control of sampling to TLC5510 and D/A diversion were achieved by programming with VHDL language. The process of analysis and synthesis misarranged the design files. It also made a statistics of consumed sources in the system. The function and timing nature of the design was tested by simulation in the simulating and verifying process for validating the work here.
