How to change name of XADC channels in hardware manager?

[sarman_1998]

Hi All,

  I'm using the XADC in a project and it would be really helpful if i could change the names of the channels as they appear in the Hardware Manager XADC window.  Is there a way to do this?

Also, it would be a really cool feature if you could enter a simple equation to be applied to readings.  This would allow the readings to be easily read if there is a voltage divider or some other device involved.

Thanks,

Eric

Hi @sarman_1998,

Do you mean changing the names such as Temp, VCCINT, VCCAUX as in the image below:

That unfortunately is not possible. Those are properties of the XADC and you can't change the names.

About the equations for readings, you can individually get the values (in decimal) for each property via TCL, and then use the TCL expr command to perform math on it.

As an example, below is a command to get a list of all the existent XADC properties:

report_property [lindex [get_hw_sysmons] 0]
Property                       Type    Read-only  Value
ADC_GAIN                       hex     true       0128
ADC_OFFSET                     hex     true       0141

lets say I'm interested in the values for VCCAUX. I can use the following command. Observe TCL returned me the value in Volts.

get_property VCCAUX [lindex [get_hw_sysmons] 0]
1.781

to perform calculations, I can actually store the value above into a variable, as below. And to read the value stored in that variable, I can use the $var_name:

set my_var [get_property VCCAUX [lindex [get_hw_sysmons] 0]]
1.781

$my_var
[1.781]

Now, I can do math with that variable using the command expr:

expr {$my_var * 2}
3.562

A list with all the possible math operations and examples in TCL is available here:

I hope that helps.

Thanks.

Hi Anunesgu,

  Adding the ability to rename those channels, either as a user defined "friendly name" in hardware manager, or in the IP wizard would be a great enhancement to Vivado.  I have seen other IP blocks that have a port renaming tab i wonder if that could be added to the XADC wizard?

Also, at least up to version 2018.1, i've noticed that in hardware manager, the Y axis of the graph for voltages won't go above 0.5V.  I understand that in one mode the XADC reads +- 0.5V but i'm using the mode that reads 0-1.0V.  It would be great if the Y axis would at least scale up to 1.0V or if the Y axis min/max could be set in hardware manager.

Thanks,

  Eric
