Description
Technical field
The present invention relates to fpga chip power supply debugging technique field, more particularly to a kind of power supply debugging apparatus based on FPGA
And method.
Background technology
Lower and lower with the core processor power consumption of electronic product, function is stronger and stronger, for the electricity of processor power supply
Source also becomes increasingly complex.One piece of processor may need a variety of different power supplys to power simultaneously for it, any one power supply is asked
Topic, processor may just can not work normally.
It is deficienter to the debugging method of power supply in the debugging process of electronic product, mainly using multimeter or show
Wave device measures the output of each power supply respectively, observation voltage whether normal, ripple whether in the reasonable scope.Therefore in measurement process,
The electric power thus supplied of one group of power supply can only be once measured, it is less efficient.And power supply persistently powers on, if there is the situation of short circuit, then PCB
Plate electrode is easily burnt, and extreme difficulties are brought for subsequent investigation work.
Invention content
In order to solve problems in the prior art, the present invention provides a kind of power supply debugging apparatus and method based on FPGA,
It uses pulsed to power on, other devices of pcb board can be protected not to be burned out in a short-circuit situation.
The technical solution adopted in the present invention is as follows：
A kind of power supply debugging apparatus based on FPGA, including FPGA chips, the control logic module that powers on of FPGA chips pass through
Power module on relay electric connection board, the element on the output end side connecting PCB board of the on board supply module, side
Pass through the voltage CL Compare Logic module of the A/D conversion chips connection FPGA chips.
The control logic module that powers on of FPGA chips passes through the I/O port connection relay.
A kind of power supply adjustment method based on FPGA, includes the following steps：
A, FPGA chips power on control logic module by I/O port, and control relay carries out pulsed on board supply and powers on；
B, after the output voltage of each group on board supply module is converted into 8 position digital signals by A/D conversion chips, it is transmitted to FPGA
The voltage CL Compare Logic module of chip；
C, fpga chip carries out discriminating comparison to collected voltage signal, to analyze the on board supply mould to go wrong
Block.
The advantageous effect that technical solution provided by the invention is brought is：
A kind of power supply debugging apparatus based on fpga chip of the present invention, by the I/O port of FPGA, control relay powers on plate
Source carries out pulsed and powers on, while after the output voltage of each group power supply is converted into 8 position digital signals by A/D conversion chips,
It is transmitted to fpga chip, fpga chip carries out discriminating comparison to collected voltage signal, to quickly find existing for power supply
Problem.Because being powered on using pulsed, other devices of pcb board can be protected not to be burned out in a short-circuit situation.
