Vivado CLOCK_DEDICATED_ROUTE

[Mell]

Hello everyone,

I use 1 pin of the pmod connector of the basys3 board for receiving a signal. So in the .xdc file i set every right but I need to say that the incoming signal is not a clock. In the help it suggests

"set_property CLOCK_DEDICATED_ROUTE value [get_nets net_name]".

I changed the net_name with the signal name "set_property CLOCK_DEDICATED_ROUTE value [get_nets echo_pin]" but u get this critical warning "Invalid option 'FALSEecho_pin' specified for'objects'.

anyone an idee? thank you

Hi @Mell,

I have moved your question to a more appropriate section of the Forum.

I'm slightly confused by the way you phrased your question. Is the signal you are providing to one of the pins on the Pmod connector of the Basys 3 a clock signal? Which pin are you using and could you provide your .xdc file so that we can look at it for ourselves?

Thanks,
JColvin

Hi @Mell,

Please attach your xdc file, hdl code and or block design and a text file with the error codes from vivado.

thank you,

Jon

@JColvin @jpeyron thank you for the interest.

I use 1 pin of the pmod connector namely the J1 pin of the pmod header JA as input for my program. All I have to do is see if that pin is high or low.

I found on the internet that the pmod standard expects a clock signal therefor it must be said that this is not a clock signal. See this video minute "17:00"

Here is my xdc file "Basys3_Master.xdc"

I use Vivado and i found this documentation. And this is the warning.

Hi @Mell,

Have you tried your project with the set_property CLOCK_DEDICATED_ROUTE FALSE [get_nets echo_pin] commented out. If so what is the error message you get. I would also suggest to look at this github project here that uses the SRF05 in VHDL.

thank you,

@jpeyron,

When I commented it out I get this error.

So I add the line that the error suggering and i only get this.

Hi @Mell,

Here is a xilinx forum thread that discusses the error you are getting. You will need to correctly name the pin that you want constrained. 

cheers,

Jon
