"LabVIEW FPGA: The compilation failed due to timing violations, but there is no path information because the timing violations are not of type PERIOD

[Pidename]

After removing the clock from project exploer, should we reinstall it again? I guess the porject needs a leat one colock.

Hello Pidename,

I would recommend adding at least one clock to your FPGA target. You can do so by right clicking on your FPGA target and navigating to New=>Base FPGA Clock.

Thanks J_bou, you are right because it cannot work without at least one clock.  The problem here is that my FPGA is set to run at 40 Mhz but for me to meet time requirement a need 15 Mhz. I can compile with 15 Mhz but when running it crashes without any output.

Hey Pidename,

Can you give me a little more infromation on the crash? Does it give you an error at all? It may be helpful if you can attach a screenshot of your code.

Hello guys,

I'm getting the same error here. Some info:

LabVIEW 2012

Target: FPGA Target (RIO0, cRIO-9082)

Compilation Tool: Xilinx 13.4

I have tried both with the local compiler and the Cloud compiler service. It's odd that sometime I am able to compile (although it was taking much longer than normal (~2h), but now it goes on to ~1h30 a gives the said error: "The compilation failed due to timing violations, but there is no path information because the timing violations are not of type PERIOD."

Is there any info from Xilinx log that you would like to see, so that it would help?

Thank you in advance,

Thank you Brian.

I assumed it was implicit, I had already tried those. None worked, unfortunately.

BR,
