Sampling voltages inside FPGA

[Gyud0]

Hey,

I would like to know how can I sample some inside FPGA's voltages? There are some internal ADCs that I connect them and read the samples from them?

For example,  The FPGA's supply voltage.

Thank you very much

可以的，使用FPGA自带的温度传感器IP，配合Nios程序即可读取6个FPGA的供电电压和2个ADC输入电压。。。

That would totally depend on which FPGA you are referring to, and you don't say at all.

Generally speaking this is not a feature FPGAs provide.

Hey,

my FPGA is Cyclone v

Hi @Gyud0 

For CycloneV, there is no Voltage/Temperature sensor circuitry/IP.
Only Arria10 and Stratix10 devices has it.

Can you give me the IP's name for the Arria10 and Stratix 10?

thank you

You can find more about the voltage/temp sensor and which device support it. Document links below.
