Timing Constraint Error in LabVIEW FPGA 8.6

Primary Software: LabVIEW Modules>>FPGA Module
Primary Software Version: 8.6
Primary Software Fixed Version: N/A
Secondary Software: Driver Software>>NI-RIO

Problem:

I tried to compile a LabVIEW FPGA VI but it fails with a timing constraint error similar to this;

 

=======================================================================

Timing constraint: TS_ TheWindowx_RioClk40Derived29x23ClkFXFromDCM1

= PERIOD TIMEGRP        

"TheWindowx_RioClk40Derived29x23ClkFXFromDCM1"        

TS_RioClk40pin / 1.26 HIGH 50%;

 

20 items analyzed, 2 timing errors detected. (1 setup error, 1 hold error)

Minimum period is 26310.429ns.

-----------------------------------------------------------------------

 

How do I fix this error?



Solution:
To fix this error, extract the attached zipped file to
labview\rvi\HDL\NiCores\ClockBoundaryCrossing\Source\DoubleSync.
Select  Yes when prompted to replace the existing file.
