| Abstract: |
| In view of the larger FPGA capacitance and longer configuration time, a
point of view that using regular design may cause the failure of the system fun
ction is presented. All kinds of Xilinx FPGA configurations are deeply described
and the advantage and disadvantage for the configuration are expatiated.At the s
ame time,the power-on timing analysis and FPGA I/O pin′s status are detailed
，which illustrates the serious influence of FPGA power-on on circuit function.
Finally,reference for the FPGA peripheral circuit design is suggested. |
