With the appearance and usage of FPGA and CPLD in modern electronic circuits,as well as the higher integrity and the faster speed of electronic devices,more rigorous requirements for the stability of electronic circuits are presented,which manifest as,the rigorous requirements of system′s power supply integrity and signal integrity on hardware. In the view of signal integrity,the Altera Cyclone IV FPGA is studied emphatically by analyzing the problems which are easy to ignore by hardware and software engineers. The stability and robustness of FPGA/CPLD system are guaranteed by hardware.
