Voltage control and test system based on FPGA

A voltage control and test system based on FPGA is introduced. Using FPGA, the system completes communication with higher level system, receiving the command and data, converting command and data to control DA and AD, thus it can implement controling the output voltage of the circuit and testing.Using Verilog to program, FPGA makes data serial, exports to DA to control the output of circuit; then controls AD to sample the output of circuit, converting data and buffering for being read. In addition, there is a serial port, and FPGA can communicate wich PC software directly through the serial port, which makes debugging and parameter calibration of circuit more convenient.
