Timing constraints to asynchronous output

I have outputs from one FPGA to another FPGA. Outputs are clocked out of one FPGA and is completely combinational in the other FPGA. Can I set false path to these outputs.

Yes. Set false paths to any input or output signals that you don't need the timing analyser to consider.

Cheers,

Hi Thanks for the Reply.

How can we determine the signals that doesn't require timing analysis?
